1.25G BiDi SFP Transceiver Pair 20km - TX1310/RX1550nm, Single Fibre LC (SFP-WDM-SM-0220A/B)

The SFP-WDM-SM-0220A/B is a matched pair of 1.25Gbps BiDi SFP transceivers that carries Gigabit Ethernet in both directions over a single strand of single-mode fibre, at distances of up to 20km. Ideal for links between buildings and sites, campus networks, CCTV backhaul and FTTB/ISP connections where only one fibre core is available.

BiDi (WDM) modules transmit and receive on different wavelengths, so one fibre core does the job of two. The A module transmits at 1310nm and receives at 1550nm, while the B module transmits at 1550nm and receives at 1310nm. Install the A module at one end of the link and the B module at the other.

Each module has a simplex LC connector and fits any compatible SFP slot on switches, routers and media converters. Check that your equipment accepts generic SFP modules before ordering.
