Cisco CRS 2-Port 40GE LAN/OTN Interface Module
Available Languages
Product Overview
This data sheet provides detailed product specifications for an important element of the Cisco® Ethernet Optimized solutions: the Cisco CRS 2-Port 40GE LAN/OTN Interface Module (Figure 1). The module connects directly into any 40 Gigabit Ethernet transport network, including traditional OC-768 transport networks, and provides two ports at 40 Gbps of data per port for 40 Gigabit Ethernet LAN physical layer (LAN-PHY) or Optical Transport Network (OTN) Transport Unit Level 3 (OTU-3) transport.
Challenge and Solution
Significant dense Packet over SONET (POS) deployments exist despite the overwhelming industry trend toward Ethernet. Operators are looking for POS-like operations, administration, and maintenance (OAM) functions at Ethernet price points with technologies such as OTN G.709 encapsulation. Some operators have traditional transponder systems that can operate only in OC-768 and OTU-3 modes.
In addition, bandwidth growth is leading all markets, including data center operators, to move to 40 Gigabit Ethernet the in aggregation layer to handle growth in the data center.
The Cisco CRS 2-Port 40GE LAN/OTN Interface Module addresses both these needs.
The 2-port 40 Gigabit Ethernet module in OTN mode with multirate serial C Form-Factor Pluggable (CFP) Fiber with Scrambled Encoding (FR) optics addresses the requirements for POS such as OAM functions at Ethernet prices, and the 2-port 40 Gigabit Ethernet module in LAN mode with CFP Long-Reach (LR) or CFP Short-Reach (SR) optics provides a dense 40 Gigabit Ethernet solution for data centers and 10 Gigabit Ethernet aggregation.
