Flexible Optical Networking

Networks are not all architected the same. Many factors, including access to physical media (that is, fiber, coaxial, etc.), CapEx budget, time to

market, etc., may influence the final design of a network. To accommodate the wide deployment needs, the Cisco ONS 15454 was designed

with a flexible, plug-and-play card architecture and comprehensive optical operating software, helping enable support for multiple capabilities

from a single platform type, including:

• Flexible bandwidth and restoration options – Network bandwidth can be matched to user demand with plug-in optical cards, with support

from 155 Mbps to 10 Gbps. In-service bandwidth upgrades provide the assurance that the network will meet today’s as well as future

demands. The platform is easily provisioned to support all SONET/SDH protection protocols, including unidirectional path switched

ring/subnetwork connection protection (UPSR/SNCP), 2- and 4-fiber bidirectional line switched ring/multiplex section-shared protection

ring (BLSR/MS-SPR), 1 + 1 automatic protection switching/linear multiplex section protection (APS/LMSP) as well as Japan APS.
