XFP	Type	Max. Length	Connector
10GBASE-SR-XFP	62.5 um MMF 200Mhz/km	33 m (108 ft)	LC
	50 um MMF 400Mhz/km	66 m (217 ft)	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.
