The ProXtend compatible DS-SFP-FC16G-LW SFP+ transceiver provides a maximum 16Gb/s throughput up to 10km over single-mode fiber (SMF), using a wavelength of 1310nm 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.
