Optical Hubbing: Dynamic Networking Across any Topology

Multiple, small rings Additional Fiber pairs required Costly OEO between rings Manual Fibering Between Rings Non-integrated spurs

Single growable structure Only 1 fiber pair between any

two sites No OEO between rings Automated connectivity between

rings Integrated spurs

Technology Breakthrough – Wavelength Selective Switch (WSS) Single, integrated device Replaces optical demultiplexer, multiplexer and optical switches Removes unnecessary loss on thru path -> more nodes, more reach,

more savings Any wavelength or any group of wavelengths to any/multiple ports Enables optical hubbing and arbitrary network topologies

“In one small region, we would have to do 30,000 individual fiber jobs without using ROADMs,” “…

transition to Ethernet becomes easier with a ROADM infrastructure because we can react

quickly.” G. Keith Cambron, SVP of AT&T labs at OFC 2006.


Automatic Power Balancing

Maintains equal channel output power in face of wavelength assignment/rearrangement/network failure

Enables software provisionable wavelength add/drop/thru and reconfigure

No manual adjustments anywhere

All wavelength power levels equal
