Modul switch de rețea MikroTik S-55DLC80D

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

How to use

Insert the S-55DLC80D module into an available SFP or SFP+ cage on a compatible MikroTik device while the device is powered down or following the manufacturer's hot-plug guidance. Connect single-mode fiber cables with LC connectors to the module's dual LC ports, verify correct fiber polarity, and configure the device's interface settings for 1.25G operation as required. Monitor link LEDs or the device interface status to confirm successful synchronization.

Recommendations

Use single-mode fiber rated for long-haul transmission and ensure clean LC connectors to minimize signal loss. Verify compatibility with the host device firmware and follow MikroTik guidelines for transceiver usage. For critical links, test end-to-end performance and consider protective enclosures for outdoor or harsh installations.
