1.25G SFP Fibre Transceiver 1310nm 40km Single-Mode Duplex LC DDM (SFP-GE-EX40)

The SFP-GE-EX40 is a 1.25Gbps SFP fibre optic transceiver for Gigabit Ethernet links of up to 40km over single-mode fibre. It operates at 1310nm and connects with a duplex LC patch lead, using one fibre to transmit and one to receive. It suits longer Gigabit fibre runs than a standard 10km LX module can cover, such as links between sites, campus backbones and ISP or wireless-network backhaul.

The module fits any compatible SFP slot on switches, routers, servers and media converters, and is hot-pluggable, so it can be installed or replaced without powering down the host. Digital Diagnostic Monitoring (DDM) lets supported equipment report the module's temperature, voltage and optical power levels, which makes it easier to monitor the link and troubleshoot faults.

Fit a matching 1310nm 40km module at the other end of the link. Achievable distance depends on the total loss of the fibre route, including splices and connectors. Check that your switch or router accepts generic SFP modules before ordering.
