MikroTik S-55DLC80D 1.25G Single-Mode SFP Module | 80km LC Transceiver
The MikroTik S-55DLC80D is a high-performance 1.25Gbps SFP optical transceiver module designed for ultra-long-distance fibre networking. Operating at a 1550nm wavelength, it supports single-mode fibre (SMF) connections over distances of up to 80 kilometres using a Dual LC UPC connector. Built with Digital Diagnostic Monitoring (DDM/DDMI), the module provides real-time monitoring of temperature, voltage, transmit power, and receive power for proactive network management. Designed for industrial environments, it operates reliably in temperatures ranging from -40°C to +70°C and is compatible with all MikroTik devices featuring SFP or SFP+ cages, as well as many third-party networking devices. The S-55DLC80D is an ideal solution for enterprise networks, ISPs, campus backbones, and long-distance fibre links.
