Interface Module

The Cisco

CRS-1 Carrier Routing System is the first carrier router offering continuous system operation,

unprecedented service flexibility, and system longevity. The Cisco CRS-1 is powered by Cisco IOS

Software – a unique self-healing, distributed operating system designed for always-on operation while

scaling system capacity up to 92 Tbps. The innovative system architecture combines the Cisco Silicon

Packet Processor, the first programmable 40-Gbps application-specific integrated circuit (ASIC), with the

Cisco Service Separation Architecture for unprecedented service flexibility and speed to service. The

Cisco CRS-1 marks a new era in carrier IP communications by powering the foundation for network and

service convergence today while protecting investments for decades to come.

This data sheet provides detailed product specifications for an important element of the Cisco IP-over-DWDM

solution, the Cisco CRS-1 1-Port OC-768c/STM-256c Tunable WDMPOS (Wavelength Division Multiplexing Packet

over SONET/SDH) Interface Module (Figure 1). The module helps service providers to increase efficiencies, improve

reliability, and reduce operational and capital costs by eliminating expensive and bulky optical transponder

equipment, even as video-based applications rapidly increase traffic in their DWDM networks. The module connects

directly into any DWDM network and provides up to 40 Gbps of data throughput across existing 10-Gbps DWDM

systems. The module is completely tunable across the C band across every other wavelength on the ITU 50-GHz

grid. It includes an integrated tunable dispersion compensator (TDC) while offering a robust tuning range. It supports

high-gain Enhanced Forward Error Correction (EFEC), extending reach up to 2000 kilometers (km) without requiring

signal regeneration. For more information about the Cisco CRS-1 or about other interfaces available for the Cisco
