Overview

What it is and who it is for

The MikroTik S-C51DLC40D is a 1.25 Gbps SFP CWDM optical module for single-mode fiber, transmitting on the 1510 nm CWDM channel with a reach of up to 40 km. It has a dual LC UPC connector and supports DDM (digital diagnostics monitoring).

It is part of the MikroTik CWDM system: with a CWDM-MUX8A at each end, up to eight links on different wavelengths from 1470 to 1610 nm share one fiber, and 1.25G SFP modules can be mixed with 10G SFP+ CWDM modules on the same system. Both ends of a link use the same 1510 nm module, and each module connects to the mux port for its wavelength.

  • Best for: Gigabit links over a CWDM system where several links share one single-mode fiber, up to 40 km.
  • System fit: MikroTik CWDM-MUX8A passive mux/demux, 1510 nm port; SFP cages on switches and routers.
  • Important to know: use a 1510 nm module at both ends of the link; reach is up to 40 km on single-mode fiber.
