MikroTik S-31DLC20D 1.25G SFP 1310 nm Transceiver 20 km

The MikroTik S-31DLC20D is a high-performance 1.25G SFP optical transceiver designed for long-distance fiber connectivity up to 20 kilometers over single-mode fiber (SMF). Operating at a 1310 nm wavelength, it features a dual LC connector and supports Digital Diagnostics Monitoring (DDM) for real-time performance and fault detection.

Engineered for reliability, low power consumption, and wide compatibility, the S-31DLC20D is fully compliant with SFP Multi-Source Agreement (MSA) standards and has been tested with popular MikroTik routers and switches including RB260GS, RB2011 series, and CCR1036-12G-4S. It also operates seamlessly with non-MikroTik SFP-compliant devices, ensuring flexibility across diverse networking environments.
