MikroTik S-C53DLC40D Fibre Transceiver Module

The MikroTik S-C53DLC40D is an SFP fiber optic transceiver module designed for single-mode links. It supports a data rate of up to 1250 Mbit/s and operates at a wavelength of 1530 nm, providing connectivity over distances up to 40 km. The module features a dual LC connector and DDM (Digital Diagnostic Monitoring) for basic status reporting. Its compact SFP form factor and nickel-coloured housing allow straightforward integration into compatible network equipment.

Advantages

The transceiver delivers stable single-mode fiber transmission at 1530 nm with support for distances up to 40 km. Its SFP interface and dual LC connector ensure compatibility with a wide range of switches and routers. Built-in DDM enables monitoring of optical parameters, and the module’s standardized form factor simplifies replacement and installation.

Suitable for

• Long-distance single-mode fiber links up to 40 km
• Connections between switches, routers, and media converters
• Network segments requiring 1.25G (1250 Mbit/s) links

How to use

Insert the S-C53DLC40D module into a compatible SFP slot on your switch, router or media converter until it clicks into place. Connect single-mode fiber cables with LC connectors to the module’s dual LC ports, ensuring correct transmit/receive alignment. Verify link status on your network device and check DDM values through the host system when available. Remove the module by disengaging any retention mechanism and gently pulling it from the SFP port.

Recommendations

Use single-mode fiber rated for the target distance and inspect fiber connectors for cleanliness before connection. Match transceiver wavelength and fiber type at both ends of the link, and ensure compatible SFP slot support on your network equipment.
