Reach of up to 40 km on standard G.652 single-mode fiber is the main job of the X2-10GB-ER, a Cisco 10GBASE-ER X2 module operating at 1550 nm. Links longer than 30 km count as engineered links. Below 20 km the module needs a 5 dB 1550 nm fixed loss attenuator, available as the spare WS-X6K-5DB-ATT=, and the minimum cabling distance is 2 m under IEEE 802.3ae.
Transmit power is 4.0 dBm maximum and -4.7 dBm minimum across 1530 to 1565 nm. Receive power runs from -1.0 dBm maximum to -15.8 dBm minimum, and the receiver tolerates 1260 to 1565 nm, though specifications hold only for a signal inside the transmit range. The connector is dual SC/PC, with PC or UPC patch cords required and APC cords not supported. It is a Class 1 laser product, hot-swappable, 91 mm x 36 mm x 13.46 mm (D x W x H) and at most 4 W.
A caution applies to the WS-X6716-10GE: X2-10GB-ER units whose serial number ends in -02 do not provide EMI compliance there. The ER is among the X2 optics the Catalyst 4948-10GE accepts, as on the WS-C4948-10GE. Shorter multimode runs use the X2-10GB-LRM, and more optics are in the Cisco interface card category.
