The Cisco® CRS-X Carrier Routing System provides outstanding economical scale, IP and optical network convergence, and a proven architecture that's delivered 10 times the capacity over 10 years. The Cisco CRS-X 4-Port 100GE LAN/OTN Interface Module is powered by advanced forwarding application-specific integrated circuits (ASICs), a chipset architecture based on multidimensional engineering, and Cisco IOS® XR Software, a unique distributed operating system.
This Cisco CRS-X interface module (Figure 1) offers the following advanced features and benefits:
• 400-Gbps line-rate throughput per slot, increasing the Cisco CRS capacity to 12.8 Tbps in a single chassis
• Advanced forwarding ASIC to support 100-Gbps single-flow traffic processing with optimized power consumption
• Superior investment protection that maintains the existing Cisco CRS architecture, making it compatible with existing Cisco CRS-1 line cards, Cisco CRS-3 line cards, and physical layer interface modules (PLIMs).
• Support for transparent In-service migration from an existing Cisco CRS-1 or CRS-3
• Space, cost, and power savings with 100-Gbps Cisco CPAK™ optics
• Flexibility through Cisco AnyPort Technology, which introduces 100-Gbps to 40-Gbps and 40-Gbps to 10-Gbps breakout options
The Cisco CRS 4-Port 100 GE LAN/OTN Interface Module connects into an existing transport network and provides four ports with 100 Gbps of data per port, for 400 Gigabit Ethernet (GE) LAN physical layer (LAN-PHY) transport or Optical Transport Network (OTN) Transport Unit Level 3 (OTU-4) transport. The interface module requires a Modular Services Card (MSC) capable of 400 Gbps, a Forwarding Processor card, or a Label Switch Processor card for operation. It is supported across the Cisco CRS 8-slot, 16-slot, back-to-back, and multichassis systems, based on either an enhanced chassis or traditional chassis. The interface module can operate in either 400-Gbps or 200-Gbps mode. The 400-Gbps mode in a Cisco CRS enhanced chassis-based system allows the interface module to deliver full 400-Gbps line-rate throughput. In 200-Gbps mode, however, two of the four ports are shut down to conserve power.
Table 1 gives specifications of the Cisco CRS-X 4-port 100GE LAN/OTN Interface Module.
