Four WWDM lanes near 1300 nm move the traffic on the X2-10GB-LX4, a Cisco 10GBASE-LX4 X2 module for multimode fiber. It supports links of 300 m on FDDI-grade multimode fiber, and the transmitter output must be coupled through a mode conditioning patch cord for the specifications to hold.
The overall wavelength range is 1269 to 1356 nm across the four lanes, with transmit power of -0.5 dBm maximum and -6.75 dBm minimum per lane. The connector is dual SC/PC with PC or UPC patch cords only, and minimum cabling distance is 2 m under IEEE 802.3ae. The hot-swappable module measures 91 mm x 36 mm x 13.46 mm (D x W x H) and has a maximum power consumption of 4 W.
It fits X2 ports on Cisco switches and routers and is among the X2 options for the Catalyst 4948-10GE, such as the WS-C4948-10GE. In the WS-X6716-10GE, units with a serial number ending in -01, -02 or -03 do not provide EMI compliance. For 220 m on FDDI-grade multimode fiber, the X2-10GB-LRM is the other multimode choice, and the Cisco interface card category covers the rest of the X2 range.
