The X2-10GB-LR is a Cisco 10GBASE-LR X2 module for 10 Gigabit Ethernet over standard G.652 single-mode fiber at 1310 nm, with links of 10 km. Minimum cabling distance is 2 m under IEEE 802.3ae. The connector is dual SC/PC, and only patch cords with PC or UPC polish are supported, not APC cords.
Transmit power is 0.5 dBm maximum and -8.2 dBm minimum across 1260 to 1355 nm. Receive power runs from 0.5 dBm maximum to -14.4 dBm minimum, and the receiver tolerates 1260 to 1565 nm, though the figures hold only for a signal inside the transmit range. The module is hot-swappable, measures 91 mm x 36 mm x 13.46 mm (D x W x H) and has a maximum power consumption of 4 W.
X2 ports on Cisco switches and routers accept it, including the WS-X6716-10GE module for the Catalyst 6500, where a unit with a serial number ending in -02 does not provide EMI compliance. It is among the X2 options for the Catalyst 4948-10GE, such as the WS-C4948-10GE. Multimode links use the X2-10GB-LRM instead, and more optics are in the Cisco interface card category.
