S2B710402RxF is a high-performance transceiver module for up to 25 Gigabit Ethernet data links over a single mode fibre. The maximum reach is 40km. The transmitter is a 1270nm Distributed Feedback (DFB) laser, the receiver is a 1310nm Avalanche Photodiode (APD). Consequently, a module with a 1310nm transmitter and a 1270nm receiver is required at the opposite side of the link. The recommended counterpart is S2B170402RxF.
