Q1: Does this 40km single fiber SFP module need to be used in pairs? What’s the wavelength combination?

A1: Yes, it must be used in pairs. One module transmits at 1310nm and receives at 1550nm, while the paired unit transmits at 1550nm and receives at 1310nm. This bidirectional design achieves 1.25G gigabit transmission over a single fiber up to 40 km.

Q2: What devices is this SC square port SFP transceiver compatible with?

A2: It adopts standard SFP form factor, compatible with most switches, media converters and routers with SFP slots. The SC square connector is easy for field wiring. Widely used in long-distance surveillance, weak current engineering and rural fiber network projects.

Q3: What are the key optical parameters? Can you provide test reports for bidding?

A3: The maximum transmission distance is 40km. We can provide optical insertion loss and sensitivity test reports as well as relevant certificates for project bidding. Bulk orders are supported, and custom labels are available for large networking projects.
