MikroTik S-4554LC80D 1.25G SFP Pair 80 km
The MikroTik S-4554LC80D is a pair of industrial-grade 1.25G SFP transceivers designed for long-distance single-mode fiber (SMF) communication up to 80 km. The package includes two complementary modules—S-45LC80D and S-54LC80D—operating at opposite wavelengths (1490 nm and 1550 nm) for bi-directional transmission over a single LC connector, effectively reducing fiber usage while maintaining high-speed connectivity.
Built for carrier-grade and harsh environments, each module supports a wide temperature range (-40°C to +85°C), ensuring stable operation in both indoor and outdoor deployments. Supporting Digital Diagnostic Monitoring (DDM), these modules allow real-time monitoring of parameters such as temperature, laser bias current, and transmit/receive power levels—making them ideal for ISPs, data centers, and enterprise fiber networks.
