OptiX OSN 1800Commissioning and Configuration Guide 3 Preparations


3-1

3.1 Preparing DocumentsFor a deployment of the OptiX OSN 1800 equipment, you need to prepare documents, includingstation bar code return table, engineering design documents, and product manuals, according tothe actual project.

Station Bar Code Return TableThe station bar code return table is used to collect the bar codes of the sets of equipment installedat a station.After all sets of equipment at a station are installed, you need to record the bar codes of theequipment in the station bar code return table. The station bar code return table shows themapping relationships between bar codes and station names. Therefore, it must be kept properlyfor future identifying the station where an NE is located when the ID and name of the NE arechanged according to the customer planning.

Engineering Design DocumentsThe engineering design documents are important inputs for equipment commissioning.Generally, the following contents are covered:l Network diagrams: describe the module types, number of add and drop wavelengths, NE

types and quantity, and NE IDs of each station, distance between adjacent stations, lineattenuation between stations, and network topology.

l Amplifier configuration diagrams: describe the amplifier configuration and line attenuationat each station.

l Wavelength allocation diagrams: describe the wavelength numbers at each station, servicerelationships between stations (add, drop, or pass-through), and wavelength protectionrelationships.

l Fiber connection diagrams: describe the internal and external fiber connectionrelationships, and slots, optical interfaces on the chassis and ODF terminals at each station.

Product ManualsThe product manuals of the OptiX OSN 1800 equipment cover the equipment functions, features,and guides to the installation, commissioning, configuration, maintenance, and troubleshootingof the equipment.In the equipment deployment phase, you are recommended to read this manual, that is, OptiXOSN 1800 Compact Multi-Service Edge Optical Transport Platform Commissioning andConfiguration Guide. The reference manuals are as follows:l OptiX OSN 1800 Compact Multi-service Edge Transport Platform Product Descriptionl OptiX OSN 1800 Compact Multi-service Edge Transport Platform Hardware Descriptionl OptiX OSN 1800 Compact Multi-service Edge Transport Platform Quick Installation and

The path is Documentation > Optical Network > OpticalNetwork Product Line > WDM > OptiX OSN 1800.

3.2 Preparing Tools, Meters, and MaterialsYou are recommended to use the Web LCT for the commissioning and configuration of theOptiX OSN 1800 equipment. The version of the commissioning tool must match the equipmentversion.

Commissioning ToolYou can use either the T2000 or the Web LCT for the commissioning and configuration of theOptiX OSN 1800 equipment.Compared with the T2000, the Web LCT has lower requirements on the computer hardware andcan be started quickly. Therefore, the Web LCT is recommended at the commissioning andconfiguration phases. The Web LCT, however, does not support query or configuration ofnetwork-level functions. Therefore, the query and configuration of network-level functions mustbe performed on the T2000.You can log in to the Web site http://support.huawei.com to download the required version ofthe T2000 and Web LCT. The path is Software Center > Version Software > Optical NetworkProduct Line > Optical Network Management System.

NOTE

The versions of the T2000 and Web LCT must match the version of the equipment. For the matchingproduct versions of this document, see About This Document.

NOTE

When you use the T2000 for the commissioning and configuration, you must be an NM user with "NEoperator" authority or higher.

Commissioning MetersAn optical power meter and an optical spectrum analyzer are mainly used for optical powercommissioning. The optical spectrum analyzer may be used only for commissioning of a networkthat is configured with optical amplifier (OA) boards.The optical power meter can be used for testing the total optical power of multiplexed signalsand optical power of the optical transponder unit (OTU) boards. The optical spectrum analyzercan be used for testing the optical power, optical signal-to-noise ratio (OSNR), and centerwavelength of a single wavelength of the multiplexed signals.You are required to test the optical power of a single wavelength of the multiplexed signals byusing the optical spectrum analyzer because the test result is more accurate and the impact ofthe noise does not need to be considered. The meters must be calibrated before being used.

4.1 Commissioning a System Without Optical AmplifiersWhen commissioning a system without optical amplifiers (OAs), pay attention to the receiveoptical power of OTU boards.

General RequirementsThe general requirements for commissioning the optical power of a system without OAs are asfollows:l The optical power after commissioning must be within the permitted range.l A certain optical power margin must be reserved to ensure that optical power fluctuation

in a certain range does not affect the existing services.

Requirements on OTU Optical PowerThe output optical power of an OTU board must conform to the optical power specifications ofthe OTU board. For details on the optical power specifications of the OTU board, see theHardware Description.After commissioning, the receive optical power of the OTU board must satisfy the followingformula: Lower threshold of the receive optical power Receive optical power of the OTUboard Upper threshold of the receive optical power. It is recommended that the receive opticalpower of an OTU board after commissioning is equal to the average value of the upper and lowerthresholds in practical application.The optical power on the WDM side of the OTU board must satisfy the following formulas:l Lower threshold of the receive optical power = Receiver sensitivity + 3 dBl Upper threshold of the receive optical power = Receiver overload point - 5 dBThe optical power on the client side of the OTU board must satisfy the following formulas:l Lower threshold of the receive optical power = Receiver sensitivity + 2 dBl Upper threshold of the receive optical power = Receiver overload point - 2 dB

General Commissioning MethodsIn general, commission a system without OAs along the signal flow, that is, from the upstreamdirection to the downstream direction, according to the requirements on the OTU optical power.Measure the receive and transmit optical power of an OTU board by using an optical powermeter, or query the receive and transmit optical power of the OTU board on the Web LCT orT2000.

CAUTIONIn the commissioning process, ensure that the input optical power of an OTU board (either theWDM or client side) is lower than the optical power at the overload point to prevent the receiveroptical module from being damaged or prevent the existing services from being affected.Exercise caution especially when an APD receiver optical module is used because the overloadpoint of such an optical module is only -9 dBm. Hence, connect a fiber loosely or do not connecta fiber to the input optical interface on the OTU board before measuring the actual input opticalpower.

If the receive optical power on the WDM side of the OTU (recorded as P1) fails to meet theoptical power requirement, do as follows:l If P1 is higher than the upper threshold of the receive optical power, attach an appropriate

fixed optical attenuator to the receive optical interface (point B in Figure 4-1) on the WDMside of the OTU board to ensure that P1 meets the optical power requirement.

l If P1 is lower than the lower threshold of the receive optical power, substitute a fixed opticalattenuator with lower attenuation for the existing fixed optical attenuator or remove thefixed optical attenuator attached to the receive optical interface (point B in Figure 4-1) onthe WDM side of the OTU board. If P1 still fails to meet the optical power requirementafter the fixed optical attenuator is removed, check whether the fiber attenuation on the lineis proper and whether the network design data is correct.

If the receive optical power on the client side of the OTU (recorded as P2) fails to meet theoptical power requirement, do as follows:l If P2 is higher than the upper threshold of the receive optical power, attach an appropriate

fixed optical attenuator to the receive optical interface (point A in Figure 4-1) on the clientside of the OTU board to ensure that P2 meets the optical power requirement.

l If P2 is lower than the lower threshold of the receive optical power, substitute a fixed opticalattenuator with lower attenuation for the existing fixed optical attenuator or remove thefixed optical attenuator attached to the receive optical interface (point A in Figure 4-1) onthe client side of the OTU board. If P2 still fails to meet the optical power requirement afterthe fixed optical attenuator is removed, check whether the transmit optical power of theupstream equipment is within the permitted range, whether the fiber attenuation on the lineis proper, and whether the network design data is correct.

If the output optical power of the OTU board fails to meet the optical power requirement onOTU boards, replace the corresponding optical module.

Tools, Meters, and MaterialsOptical power meter, Web LCT or T2000, fiber jumpers (two FC/PC-FC/PC, LC/PC-LC/PC,and LC/PC-FC/PC fiber jumpers), several fixed optical attenuators (3 dB, 5 dB, 7 dB, 10 dB,and 15 dB), fiber adapters, fiber cleaning tissue or cassette cleaner, and compressed air cleaner.

4.2 Commissioning a System with Optical AmplifiersWhen commissioning the optical power of a system with optical amplifiers (OAs), pay attentionto the output optical power of OAs, the receive optical power of corresponding OTU boards,and the input optical power of the DCM module.

General RequirementsThe general requirements for commissioning the optical power of a system with OAs are asfollows:l The optical power after commissioning must be within the permitted range.l A certain optical power margin must be reserved to ensure that optical power fluctuation

in a certain range does not affect the existing services.l The optical power after commissioning must meet the requirements on system expansion.

Requirements on OTU Optical PowerThe output optical power of an OTU board must conform to the optical power specification ofthe OTU board. For details on the specifications of the OTU board, see the HardwareDescription.After commissioning, the receive optical power of the OTU board must satisfy the followingformula: Lower threshold of the receive optical power Receive optical power of the OTUboard Upper threshold of the receive optical power. It is recommended that the receive opticalpower of an OTU board after commissioning is equal to the average value of the upper and lowerthresholds in practical application.The optical power on the WDM side of the OTU board must satisfy the following formulas:l Lower threshold of the receive optical power = Receiver sensitivity + 3 dBl Upper threshold of the receive optical power = Receiver overload point - 5 dBThe optical power on the client side of the OTU board must satisfy the following formulas:l Lower threshold of the receive optical power = Receiver sensitivity + 2 dBl Upper threshold of the receive optical power = Receiver overload point - 2 dB

Requirements on OA Optical PowerThe average output optical power of the wavelengths of an OA must be equal to the nominaloutput optical power for a single wavelength. In this case, the following requirements must bemet:




Issue 02 (2010-09-30)

l The average output optical power of the wavelengths of an OA is measured by connectingan optical spectrum analyzer to the OUT optical interface on the OA.

l Nominal output optical power for a single wavelength = Maximum total optical power ofthe OA - 10lgN (N represents the maximum number of wavelengths permitted by thesystem). For example, the maximum total optical power of the OA is 17 dBm. If the systemis designed as a 40-channel system, the nominal output optical power for a singlewavelength is 1 dBm as calculated by using the preceding formula.

The output optical power of a single wavelength of the OA should be equal to or close to thenominal output optical power for a single wavelength.

Requirements on DCM Optical PowerIf a DCM module is configured in a system, the optical power of a single wavelength input tothe DCM module must be equal to or lower than -3 dBm.

General Commissioning MethodsIn general, commission a system with OAs along the signal flow, that is, from the upstreamdirection to the downstream direction, according to the requirements on the OA optical power,OTU optical power, and DCM optical power.The optical power of an OTU board is commissioned in the same way regardless of in a systemwith OAs or a system without OAs. For the detailed methods of commissioning the optical powerof an OTU board, see 4.1 Commissioning a System Without Optical Amplifiers.

CAUTIONIn the commissioning process, ensure that the input optical power of an OTU board (either theWDM or client side) is lower than the optical power at the overload point to prevent the receiveroptical module from being damaged or prevent the existing services from being affected.Exercise caution especially when an APD receiver optical module is used because the overloadpoint of such an optical module is only -9 dBm. Hence, do not connect a fiber or connect a fiberloosely to the input optical interface on the OTU board before measuring the actual input opticalpower.

Connect an optical spectrum analyzer to the OUT optical interface on an OA, and then measurethe output optical power of a single wavelength and the average output optical power of thewavelengths of the OA. If the output optical power of a single wavelength of the OA fails tomeet the optical power requirement, adjust the optical attenuator at the WDM-side output opticalinterface on the upstream OTU board or adjust the optical attenuator at the input optical interfaceon the OA to ensure that the optical power of the OA meets the optical power requirements.See Figure 4-2. In the case of OA1, do as follows:l If the average output optical power of wavelengths is higher than the nominal output optical

power for a single wavelength, increase the attenuation of the optical attenuator at the inputoptical interface (point as D in Figure 4-2) on the OA to ensure that the average opticalpower of wavelengths is equal to the nominal output optical power for a single wavelength.

l If the average output optical power of wavelengths is lower than the nominal output opticalpower for a single wavelength, decrease the attenuation of the optical attenuator at the inputoptical interface (point as D in Figure 4-2) on the OA to ensure that the average opticalpower of wavelengths is equal to the nominal output optical power for a single wavelength.

l In the case of the output optical power of a specific wavelength, adjust the optical attenuatorat the output optical interface (point C in Figure 4-2) on the corresponding OTU board toensure that the output optical power of this wavelength from the OA is equal to or close tothe nominal output optical power for a single wavelength.

In the case of OA2, adjust the optical attenuator at point E in Figure 4-2 to ensure that the averageoptical power of wavelengths is equal to the nominal output optical power for a singlewavelength. If the average output optical power of wavelengths cannot be equal to the nominaloutput optical power for a single wavelength after the attenuation is adjusted to 0, remove theoptical attenuator. If the optical power requirement is still not met, check whether the networkdesign data is correct.In the case of OA3, adjust the input optical power of the MUX2 board at the upstream station,and then adjust the optical attenuator at point F in Figure 4-2 to ensure that the average outputoptical power of wavelengths of the OA is equal to the nominal output optical power for a single




Issue 02 (2010-09-30)

wavelength. The methods of commissioning the input optical power of the MUX2 board are asfollows:1. Measure the optical power of each pass-through wavelength at the input optical interface

on the MUX2 board and then calculate the average optical power of these pass-throughwavelengths. In the case of a multiplexed pass-through wavelength, measure the averageoptical power by using an optical spectrum analyzer. In the case of a single pass-throughwavelength, measure the optical power of this pass-through wavelength directly by usingan optical power meter.

2. Measure the optical power of a single add wavelength at the input optical interface on theMUX2 board and identify the add wavelength with the lowest optical power.

3. Do as follows to adjust the optical power of corresponding wavelengths:l If the average optical power of the pass-through wavelengths is lower than the lowest

optical power of the add wavelengths, adjust the optical attenuator at point G in Figure4-2 to ensure that the optical power of each add wavelength is equal to the averageoptical of the pass-through wavelengths.

l If the average optical power of the pass-through wavelengths is higher than the lowestoptical power of the add wavelengths, install one optical attenuator on each pass-throughchannel between the DUX1 and MUX2 boards to ensure that the average optical powerof the pass-through wavelengths is equal to the lowest optical power of the addwavelengths. In addition, adjust the attenuation of the optical attenuators at the outputoptical interfaces on other OTU boards used to add wavelengths. This is to ensure thatthe optical power of each add wavelength is equal to the lowest optical power of theadd wavelengths as measured at the input optical interface on the MUX2 board.

TIPIf the OPU board is configured with SFP EVOA, the attenuation value can be adjusted on the NMS.

If a DCM module is configured in the system, measure the total input optical power of the DCMmodule by using an optical power meter. Then, calculate and ensure that the actual input opticalpower of a single wavelength is equal to or lower than -3 dBm.

Tools, Meters, and MaterialsOptical power meter, optical spectrum analyzer, Web LCT or T2000, fiber jumpers (two FC/PC-FC/PC, LC/PC-LC/PC, and LC/PC-FC/PC fiber jumpers), several fixed optical attenuators(3 dB, 5 dB, 7 dB, 10 dB, and 15 dB), fiber adapters, fiber cleaning tissue or cassette cleaner,and compressed air cleaner.

5 Commissioning and Configuring theNetwork

About This Chapter

You can commission and configure the network after the equipment at each station on thenetwork is powered on and the stations are interconnected with fibers.

5.1 Searching for and Creating NEsYou can search for and create NEs when the NEs are connected to the NMS computer and thecommunication between NEs and the NMS is normal.5.2 Creating Optical NEsOn the T2000 the WDM equipment is allocated to different optical NEs for management.5.3 Changing the ID and Name of an NEThe ECC protocol uses an NE ID to uniquely identify an NE. When planning the network, youmust assign a unique ID for each NE. If an NE ID conflicts with another one, ECC routingcollision is caused. In this case, certain NEs cannot be managed.5.4 Changing the IP Address of an NEIn the case of a gateway NE, change the IP address of the NE according to the customer planning.In the case of a non-gateway NE, you do not need to change its IP address.5.5 Configuring Ethernet Extended ECCWhen there is no OSC or ESC communication between two or more NEs, the Ethernet ports ofthe NEs can be used to achieve the extended ECC communication. By default, the OptiX OSN1800 series NEs take the auto-extended ECC communication. When the number of NEs that usethe extended ECC communication exceeds nine, you must set the extended ECC communicationto specified mode.5.6 Configuring IP over DCCWhen the network planning adopts the IP over DCC mode for communication, you need toconfigure the DCC channel and check whether the IP routes are correct in the commissioningand configuration.5.7 Configuring Board Parameters

Different boards implement different functions, and therefore you need to configure differentparameters in the commissioning and configuration for deployment. Set parametersappropriately for each board according to the actual network.5.8 Creating FibersYou are recommended to create fibers in graphic mode in the Main Topology or signal flowview.5.9 Configuring Cross-Connection ServiceThe LQG and LQM2 boards support configuration of cross-connections and the methods ofconfiguring cross-connections on the two boards are the same. By default, a cross-connectioncreated on the LQG and LQM2 boards is a direct cross-connection.5.10 Configuring Services in Service Package ModeThe service package module enables you to configure services on an NE in a one-click manner.This configuration method is easier and quicker. The OptiX OSN 1800 supports two types ofservice packages: GE service package and GE/STM-1 integrated service package. The LQM,LQM2, and LWX2 boards support the function of configuring services in service package mode.5.11 Configuring SW SNCP ProtectionSW SNCP protection can be implemented by using convergence OTU boards that support cross-connections. This type of OTU boards includes the LQM2 and LQG boards.5.12 Configuring Port ProtectionOn the port protection user interface, you can configure intra-board 1+1 protection, optical lineprotection, client-side 1+1 protection, and inter-subrack 1+1 optical channel protection.Configure protection of an appropriate type according to the network design.5.13 Synchronizing the NE Time with the NMS TimeWith the time synchronization function, the NE time is kept consistent with the NMS time. Inthis way, the NMS is able to record the correct time when alarms and abnormal events arereported by NEs.5.14 Starting NE Performance MonitoringEnabling the performance monitoring function is a precondition for querying the performanceevents. If the current NE time is in the performance monitoring time range as set before, the NEmonitors its performance events automatically. If the performance monitoring time range is notset or if the current NE time is not within the performance monitoring time range, the NE doesnot monitor its performance events.5.15 Searching and Creating WDM TrailsAfter configuring services on an NE, search for WDM trails on the NE so that you can manageservices based on WDM trails.5.16 Checking Configurations in the Commissioning ProcessCorrect setting of each system parameter is the precondition for ensuring normal networkoperation.5.17 Backing Up the NE Database to the SCC BoardBy backing up an NE database to an SCC board, you can ensure that the NE automaticallyrestores to the normal state in case a power failure occurs. When you back up an NE databaseto an SCC board, you actually back up the NE data to the flash memory of the SCC board. Aftera power-off reset occurs on the NE, the SCC board automatically reads the configuration datafrom the flash memory and applies the data to the boards on this NE.5.18 Checking Optical Power of BoardsBy checking the optical power of a board, you can ensure that the transmit and receive opticalpower of the board is within the normal range. When commissioning the OptiX OSN 1800, you

5 Commissioning and Configuring the NetworkOptiX OSN 1800



Issue 02 (2010-09-30)

can adjust the optical power of a board at the site by adding, replacing, or removing a fixedoptical attenuator (FOA) or adjusting a variable optical attenuator (VOA) before an opticalinterface.5.19 Querying Bit Errors Before and After FECThe count of bit errors before and after FEC is a key specification for measuring the systemoperation quality.5.20 Viewing Current Alarms on an NE and Removing Abnormal AlarmsViewing the current alarms on an NE helps you to intuitively and quickly locate an exceptionon the network. This helps you to identify a fault on the network.5.21 Testing Protection SwitchingIn the commissioning or configuration phase, you can run a manual switching command to checkwhether protection switching can be performed normally.5.22 Querying and Saving the Networkwide Optical Power and Alarm DataAfter commissioning a network, you need to query and save the optical power and alarm dataof the entire network. This type of data can help you analyze and understand the operating statusof the network in future.5.23 Backing Up NE Data to the NMS Server or ClientYou can manually back up the data of one or more NEs of the same type to an NMS server orclient.
