1.Cable distances are based on fiber loss. Additional factors, such as the number of splices and the optical quality of the fiber, can affect cabling distances. The minimum cabling distance for optical X2 transceiver types (LX4, SR, LR, and ER) is 6.6 ft (2 m) according to the IEEE 802.3ae standard. The minimum cabling distance for the X2-10GB-LRM is 1.6 ft (0.5 m) according to IEEE 802.3aq standard.
2.The Cisco X2-10GB-CX4 transceiver supports link lengths of up to 49.2 feet (15 m) on CX4 cable. Cisco offers four CX4 cables: CAB-INF-28G-1= (1 meter cable), CAB-INF-28G-5= (5 meter cable), CAB-INF-28G-10= (10 meter cable), and CAB-INF-26G-15= (15 meter cable).
3.The Cisco X2-10GB-LX4 transceiver supports link lengths of 300 meters on standard Fiber Distributed Data Interface (FDDI) grade multimode fiber (MMF). To ensure that specifications are met, the transmitter output should be coupled through a mode conditioning patch cord. Cisco offers two mode conditioning patch cords: CAB-GELX-625= (mode conditioning patch cable, 62.5 microns, dual SC connectors) and CAB-MCP50-SC= (mode conditioning patch cable, 50 microns, dual SC connectors).
4.The Cisco X2-10GB-LRM transceiver supports link lengths of 220 meters on standard Fiber Distributed Data Interface (FDDI) grade multimode fiber (MMF). To ensure that specifications are met over FDDI-grade, OM1 and OM2 fibers, the transmitter should be coupled through a mode conditioning patch cord. Cisco offers two mode conditioning patch cords: CAB-GELX-625= (mode conditioning patch cable 62.5 microns, dual SC connectors) and CAB-MCP50-SC= (mode conditioning patch cable 50 microns, dual SC connectors). No mode conditioning patch cord is required for applications using OM3.
5.Requires a 5 db 1550 nm fixed loss attenuator for cable distances less than 12.43 miles (20 km). The attenuator is available from Cisco Systems (p/n WS-X6K-5DB-ATT=)
