Challenge The “10 x” Problem

10x Higher Speed Services 10x Higher Capacity 10x Greater Density 10x Reliability Simultaneously !

…and Why ?


Average Traffic per Month (Internet Household)

Complexity of technology & deployment

Type of FTTH as a green or brown field Network architecture P2P or P2MP. Local labor costs, local Regulatory , … Termination Point ( FTTH, FTTB, …)

The main factors affecting the infrastructure deployment are:

Which technology addresses better the requirement (...maybe a combination) ?

Bandwidth availability & capacity, Maintenance & fault isolation The use of existing infrastructure?


Layer 1 is the Bridge between

The network as a chain of dependencies

The Layer 1 could be your “weakest Link”

“Secure & Speed Transmission”

Highquality Products will determine the reliability of the network.


Consumers expect from superfast broadband:

Upgrade / extension

Modularity ensures extension of systems

Modular systems assure adaptation and extension

Scalability “grow as your investment”

Operation

Constant transmission throughout the entire service life

Maintenance with minimal effect on links in operation

Secure Fiber Management prevents performance loss

Challenges for FTTH Network

OPEX

Reduction of network downtime

Reduction of network maintenance

Product design which supports easy Installation

Trained persons


• From ODF=> P2P / SCM

• Subscriber Individual Fibers

• Maintenance with minimal effect on links in operation

• 4 Singlemode Fibers spliced in an OTO (Opical Outlet)

• CPE device customers - 4-Port Ethernet Switch - Optional Wireless ( > 160 Channels

• Physical separation of the subscriber (SCM) • Fiber in the Loop • Implementation of splitters • Labeling system ( Numbers and Colours)

Up to 72 Subscribers

The right selection depending on the technology und the area in use

FO Outlet Splice • Integrated individual dust covers • Slim design, only 15mm high (without lid) • Separate areas for fibers and couplers • Simple and fast installation (time saving)

FO Outlet “field” • Flat and thin design • Preterminated cables • Field installable connectors


Conclusion; Complexity as a Challenge

Modularity & Flexibility for Adaptation, Combination and Expansion Reliability and Security through Quality Products Don‘t forget the OPEX ( maintenance and troubleshooting) The Network is only as Good as the Investment
