MikroTik S-85DLC05D 1.25G SFP 850nm Transceiver

The MikroTik S-85DLC05D is a 1.25G SFP optical transceiver engineered for high-speed Gigabit Ethernet connections over multimode fiber (MMF). Operating at an 850 nm wavelength, it delivers up to 550 meters of data transmission, making it ideal for short-to-medium distance backbone links, switch uplinks, and router interconnects in enterprise and ISP environments.

This transceiver adopts the standard SFP (Small Form-Factor Pluggable) form factor for seamless integration with compatible MikroTik devices such as RB2011, CCR, and RB260 series, as well as third-party equipment supporting MSA-compliant SFP modules. The Digital Diagnostics Monitoring (DDM) functionality enables real-time tracking of critical optical parameters such as temperature, voltage, and optical power — improving reliability and proactive maintenance of optical links.
