	10GBASE-LR-XFP	SMF	10 km (6.21 mi)	LC

	10GBASE-ER-XFP1	SMF	40 km (24.85 mi)	LC

1.The 10GBASE-ER-XFP requires a minimum of 5 dB attenuation or a cable length of about 10 km.

The uplinks have one fiber‐optic interface with an LC connector. Depending on the XFP and fiber‐optic cable used, the signal can be driven to a maximum distance of 33 m (108 ft) to 40 kilometers (24.85 miles).

The device at the other end of the fiber optic connection must be a standards‐compliant product with a matching IEEE 802.3ae 10‐Gigabit Ethernet (10 GbE) interface transceiver.
