The ProXtend compatible SFP-10G-ER SFP+ transceiver provides a maximum 10Gb/s throughput up to 40km over single-mode fiber (SMF), using a wavelength of 1550nm via an LC connector. The transceiver has been preprogramed, data traffic and application tested, guaranteeing that it is 100% compatible and will perform the same as the original Cisco equivalent.
