## Long description

The MikroTik S-55DLC80D is an industrial temperature grade SFP transceiver module designed for long-distance optical links up to 80 km. Operating at a wavelength of 1550 nm and featuring a dual LC connector, this 1.25G module is compatible with MikroTik devices that provide SFP or SFP+ cages and is intended for reliable point-to-point fiber connections in demanding environments.
Advantages
This module supports an industrial operating temperature range from -40°C to +85°C, ensuring stable performance in extreme conditions. With a 1.25G data rate and a wavelength of 1550 nm it provides low-loss transmission over single-mode fiber for extended distances. The dual LC connector design simplifies integration into standard fiber patching and the module is directly compatible with MikroTik equipment that accepts SFP/SFP+ transceivers.
Suitable for
Long-distance point-to-point fiber links up to 80 km
Industrial and outdoor network deployments operating in extreme temperatures
Connecting remote sites, base stations or backbone segments
Replacement or upgrade of SFP ports in MikroTik switches and routers
