The SFF is a legacy form factor transceiver line. The SFF comes in 2x5 and 2x7 pin configurations, the latter providing digital diagnostic capabilities for the device. COTSWORKS offers both multimode and singlemode SFFs, in standard duplex and single fiber configurations, as well as dual transmitter and dual receiver options. SFF transceivers support 100Mbps-3Gbps in singlemode, and 100Mbps to 4Gbps in multimode.
