MikroTik S+31DLC10D 10G SFP+ Single Mode Transceiver for Enterprise & Industrial Networks

S+31DLC10D is an industrial-grade 10G SFP+ module for single-mode optical connections of up to 10 kilometers, designed for backbone networks, campuses, and ISP infrastructures where 10-Gigabit long-distance connectivity over single-mode fiber is an essential requirement. It is the cost-effective alternative to the XS+31LC10D, delivering all the functionality needed for 10G networks without the cost of 25G SFP28 support.

The module operates at 1310nm wavelength with a Dual LC connector for full-duplex operation and includes comprehensive DDM (Digital Diagnostic Monitoring) — real-time monitoring of transmit and receive optical power, supply voltage, temperature, and laser bias current. This data enables early detection of anomalies, proactive maintenance planning, and informed infrastructure upgrade decisions based on actual performance metrics rather than estimates. Industrial-grade build quality and an MTBF of 100,000 hours ensure reliability for permanent installations in production environments.

S+31DLC10D installs directly into any standard SFP+ slot, compatible with MikroTik equipment and third-party devices with SFP+ ports. The 10km reach covers connectivity needs in metropolitan networks, between campuses, or between ISP network nodes, leveraging existing single-mode fiber infrastructure without additional cabling investment.

Recommended for ISPs and integrators building or expanding 10G backbone networks over single-mode fiber, for connections between campuses or distant buildings up to 10km, and for any infrastructure where advanced DDM and industrial-grade quality are operational requirements. The smart choice for 10G networks that do not require 25G support, delivering full performance at approximately half the price of the XS+31LC10D.
