Accelerating New Application Adoption

SONET/SDH to Packet Optical Migration

ADTRANs ONE reduces typical packet optical network complexity

by uniquely packaging advanced optical transport technologies

allowing operators to accelerate next generation service

delivery and service migration strategies.

Application-optimized packet optical solution supports SONET/SDH services migration to IP/Ethernet and OTN

Service providers require cost-effective, simplified approaches

to effectively deliver, aggregate and transport a mix of growing

next-generation IP/Ethernet services and a large, incumbent

SONET/SDH service network.

Over a decade ago, TDM and PDH service expansion led to the deployment of SONET/SDH networks to support the ramp-up of new residential, commercial and mobile backhaul services. This expansion required circuit-based PDH/TDM access, such as T1, E1 and J1 services. This resulted in the deployment of many SONET/SDH networks to aggregate and transport these growing, circuit-based services, many of which continue to deliver significant, though declining, revenue streams. However, new next-generation services based on Ethernet are rapidly expanding as demand is increasing among almost every enterprise vertical ranging from healthcare and finance to education and are scaling to near gigabit per second levels. Many analysts forecast Ethernet service revenue will grow to $40 billion (USD) by 2015. However, it is not just enterprise verticals that are driving the demand for packet-based service and transport architectures. 1 Mbps DSL residential services are being replaced by 100 Mbps or more Fiber-to-the-Home (FTTH) deployment models. Businesses are no longer satisfied with sub-10 Mbps TDM/PDH-based access services and are demanding 100 Mbps and greater Ethernet LAN extension services to support cloud computing initiatives on a global level. Rich 4G mobile broadband applications are driving the need for bandwidth connections of 100 Mbps and beyond resulting in the need for gigabit Ethernet services at the cell site. With all of this service expansion, fiber infrastructure is being stressed. Wavelength Division Multiplexing (WDM) based on fixed optics has provided relief, allowing multiple virtual paths per fiber facility. However, the effort to change these predetermined virtual paths is operationally expensive and new service architectures demand services access and aggregation flexibility.

ADTRAN® developed the Optical Networking Edge (ONE) solution based on the latest packet optical technologies to enable service providers to dramatically simplify service delivery and network operation, while accelerating time to revenue. ONE provides agile photonics and enhanced multi-service delivery with the introduction of a right-sized, compact Reconfigurable Optical Add/Drop Multiplexer (mini-ROADM) system-on-a-blade. This is complemented by multi-service Optical Transport Network (OTN, ITU-T G.709) Switchponder, scalable Carrier Ethernet delivery with subtended networking and tunable/pluggable optics. This solution provide operators with flexible and efficient network architectures improving their market responsiveness to ever-changing service and network requirements driven by traffic growth and the transition from circuit to packet services.

ADTRAN’s OTN Switchponder is a multi-service unit that integrates an OTN switch with a DWDM transponder within a single module. It provides remotely configurable any-service to any-port operation. It delivers OTN mapping, switching, aggregation and transport capabilities, allowing operators to simultaneously transport SONET/SDH, Ethernet or other services such as Fibre Channel.

ADTRAN’s mini-ROADM delivers a system-on-a-blade including Wavelength Selective Switch (WSS), EDFA amplifiers, optical monitoring and auto power balancing all on a single module.

Right-sized, Agile Photonics and Switching for Services and Transport Flexibility

As SONET/SDH/fixed WDM photonic networks attempt to support the large influx of packet-based services from varying service segments the following issues result:

• Slowed revenue growth due to limited service scale and lack of next-generation service support

• Reduced service agility due to limited network flexibility

• Higher operational cost due to increased infrastructure costs

• Stranded revenue streams due to near-term, end-of-life network gear

Benefits of ADTRAN Optical Networking Edge• Integrated service delivery

and transport

• Right-sized optical networking: Carrier Ethernet, OTN, mini-ROADM

• Unmatched multi-service scalability

• Reduced network complexity

• Flexible service migration and delivery

• Pay-as-you-grow modularity

• Fast time to revenue

With legacy service migration and a new revenue expansion deployment model, the ADTRAN ONE architecture offers the following network and service delivery benefits:

• Expedited service delivery and transport network installation and upgrade

• Simplified remote provisioning and performance monitoring tools eliminating truck rolls;

• Reduced network complexity, space and power needs when compared to alternative ROADM architectures that typically require a multi-blade implementation and a separate service delivery platform.

• Increased access, aggregation and transport service capacity on demand (up to 44 x 10G DWDM channels with total capacity of 440G, scalable to 88 channels and 100G wavelengths)

• Improved network flexibility and simplified multi-service delivery (residential, business and backhaul) with integrated packet optical networking enabling service providers to extend packet optical aggregation and scalability to the network edge.
