MikroTik S-4554LC80D par SFP modula – jednomodni, 80 km

A pair of industrial temperature grade (-40°C to +85°C) SFP modules for single-mode fiber links up to 80 km. The set contains one S-45LC80D (T1490nm/R1550nm) and one S-54LC80D (T1550nm/R1490nm). Both modules operate at 1.25 Gbps, use LC connectors, support DDM and are compatible with MikroTik devices that provide SFP or SFP+ cages.

Advantages

Designed for industrial temperature ranges, these single-mode SFP modules support long-distance links up to 80 km and provide digital diagnostic monitoring (DDM) for real-time fiber transceiver status. The matched Tx/Rx wavelengths (1490/1550 nm and 1550/1490 nm) allow straightforward deployment in point-to-point fiber connections while LC connectors ensure wide compatibility with networking equipment.

Suitable for

• Point-to-point long-distance fiber links up to 80 km
• MikroTik routers and switches with SFP or SFP+ cages
• Industrial environments requiring -40°C to +85°C operating range
• Network segments needing monitoring via DDM

How to use

Install one module in each end of the single-mode fiber link so that the Tx wavelength of one module matches the Rx wavelength of the other (S-45LC80D ↔ S-54LC80D). Insert the SFP modules into SFP or SFP+ cages on compatible MikroTik devices, secure the modules according to the device manual, and connect LC-terminated single-mode fiber cables. Verify link status on the network device and monitor transceiver parameters through DDM where supported.

Recommendations

Handle the modules by the housing, avoid touching the fiber connector end faces, keep dust caps on until connection, and follow the host device guidelines for hot-plugging. For reliable long-distance operation, use ITU-compliant single-mode fiber and check link budget for losses and splices before deployment.
