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 XENPAK 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 XENPAK-10GB-LRM is 1.6 ft (0.5 m) according to IEEE 802.3aq standard. 2. The Cisco XENPAK-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 XENPAK-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. ITU-T G.652 SMF as specified by the IEEE 802.3z standard. Even though dispersion-shifted optical fiber reduces signal dispersion, which allows the signal to travel farther, signal attenuation still limits its distance. 5. The Cisco XENPAK-10GB-LRM transceiver supports link lengths of 220m 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. 6. The XENPAK-10GB-LW (WAN PHY) supports a link length of 6.2 miles (10 km) on standard SMF (G.652). 7. 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=) B-10 Catalyst 6500 Series Ethernet Modules Installation Guide OL-6265-03
