The Cisco® CRS-1 Carrier Routing System offers continuous system operation, exceptional service flexibility, and system longevity. The Cisco CRS-1 is powered by Cisco IOS® XR 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 superior 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.
Product Overview
This data sheet provides detailed product specifications for an important element of the Cisco IP-over-DWDM solution, the Cisco CRS-1 4-Port 10GE Tunable WDMPHY Interface Module (Figure 1). This tunable DWDM interface module allows service providers to increase efficiencies, improve reliability, and reduce operational and capital costs through elimination of expensive and bulky optical transponder equipment, even as video-based applications rapidly increase traffic in their DWDM networks. The module supports both G.709 Generic Forward Error Correction (GFEC) and high-gain Enhanced Forward Error Correction (EFEC), extending reach up to 2000 kilometers (km) without requiring signal regeneration. The Cisco CRS-1 4-Port 10GE Interface Module is also completely tunable across the C band with 50-GHz spacing, and supports router-to-router SONET/SDH-like operations, administration, maintenance, and provisioning (OAM&P).
