Provides rapid turn up of new wavelengths and sites
Allows efficient creation of access / subtended DWDM
rings off backbone network
Does not require back to back DWDM nodes
DWDM Subtending Network
In-service installation
Add pair of optical amps to feed subtending network
Eliminates back to back WDM systems
Reduces cost of adding subtending DWDM network
92% reduction of cost associated at multi-degree site
Translates into 43% savings in adding 3 node 4λ ring

Transport network impact
Packet optics allows for efficient IPTV feeder distribution
Packet optics allows multicast of video
Packet optics allows statistical multiplexing of data communication
Reduces bandwidth demands by 60% to 85%
IP/MPLS core impact
Packet optics provides aggregation of GbE trunks to the core
Reduces line ports by 60% to 90%
Reduces core & transport capital requirements at initial phase
Greater levels of aggregation can be used until higher take rates
