1.25G SFP Fibre Transceiver 1550nm 120km Single-Mode Duplex LC DDM (SFP-GE-ZX120)

The SFP-GE-ZX120 is a 1.25Gbps SFP fibre optic transceiver for Gigabit Ethernet links of up to 120km over single-mode fibre. It operates at 1550nm and connects with a duplex LC patch lead, using one fibre to transmit and one to receive. It's designed for extended-reach Gigabit links in service-provider, metropolitan and backbone fibre networks, where 10km to 80km modules can't cover the distance.

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 1550nm 120km 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.
