Product information

Description

The Mikrotik S-31DLC20D is a 1.25G SFP transceiver module operating at a wavelength of 1310 nm with a dual LC connector. Designed for single-mode fiber links up to 20 kilometers, the module supports a maximum data rate of 1250 Mbit/s and includes Digital Diagnostic Monitoring (DDM) for link and module status monitoring. It is compatible with a range of MikroTik devices and can interoperate with non-MikroTik SFP ports that accept standard SFP modules.

Advantages

The S-31DLC20D provides single-mode fiber connectivity over distances up to 20 km while maintaining a standard 1.25G SFP form factor. Built-in DDM enables real-time monitoring of optical parameters. Its LC duplex connector and 1310 nm wavelength suit common long-reach fiber deployments, and the module is tested for compatibility with multiple MikroTik router and switch models.

Suitable for

  • Long-reach single-mode fiber links up to 20 km
  • Upgrading MikroTik RB260GS, RB2011 and CCR1036 series with SFP ports
  • Interoperable connections between switches and routers using SFP modules

Key specifications

  • Interface type: SFP
  • Data rate: 1250 Mbit/s (1.25G)
  • Wavelength: 1310 nm
  • Connector: Dual LC (duplex)
  • Reach: Up to 20 km (single-mode fiber)
  • Features: DDM (Digital Diagnostic Monitoring)

How to use

Insert the S-31DLC20D into a compatible SFP slot on the network device until it seats securely. Connect LC duplex single-mode fiber cables to the module, observing transmit/receive orientation. Verify link status and data rate through the host device interface; use DDM readings if supported by the host to check optical power and temperature. Remove the module by disengaging any retention latch and pulling it straight from the SFP port.

Usage recommendations

Use single-mode LC duplex fiber patch cables rated for the intended distance and verify compatibility with the host device firmware. Avoid bending the fiber beyond recommended radii and ensure dust caps are used when the module is not connected.
