Small rectangular SFP transceiver module with dual LC ports and black finish

Mikrotik

Mikrotik S-85DLC05D SFP transceiver 1.25G MM 550m 850nm

SKU CH-PCQP-RJMBP

1.25G SFP transceiver with 850nm dual LC connector for 550m multi-mode fiber links and digital diagnostics

  • Device TypeTransceiver
  • 25G data rate for fast network links
  • 550 m reach over multi-mode fibre
  • 850 nm wavelength suits short-range deployments
  • Dual LC connector fits standard patch panels
  • DDM support enables real-time link monitoring

What this module is

The MikroTik S-85DLC05D is a 1.25G SFP transceiver built for short-range multimode fibre links. It suits network operators who need a hot-pluggable optics module for switches and routers with SFP cages.

Reach and wavelength decide fit

This unit uses an 850nm wavelength and a Dual LC connector to deliver up to 550 meter reach on multimode fibre. If your link exceeds that distance or runs on single-mode cable, a different transceiver is required.

DDM and broad compatibility simplify deployment

Digital Diagnostics Monitoring lets you watch temperature, voltage and optical power in real time. The module is tested with RB260GS, RB2011 and CCR1036-12G-4S hardware and also works with non-MikroTik SFP equipment.

Questions about this item

What does the 1.25G data rate mean once the S-85DLC05D is installed in a switch?

It provides a 1.25 Gbps optical link over multi-mode fibre, suitable for Gigabit Ethernet connections between MikroTik routers such as the RB2011 or CCR1036 series and other SFP equipment.

What does the Dual LC connector and SFP format cap in practice?

The Dual LC interface accepts standard duplex multi-mode patch cords, while the SFP form factor fits any SFP cage on compatible MikroTik models or third-party switches and routers.

What physical space and fibre type does the S-85DLC05D need to fit and work?

It occupies a single SFP slot and requires 850 nm multi-mode fibre with a dual LC patch cable to reach the rated 550 m distance.
