The MikroTik S+31DLC10D is a reliable, industrial-grade 10G SFP+ module designed for long-distance single-mode links up to 10 km. It uses the widely supported 1310 nm wavelength and a dual-LC connector for full- duplex operation, making it a perfect fit for backbone links, campus networks, industrial deployments, and ISP infrastructure.

This new model delivers all the essential features of our popular XS+31LC10D, but at almost half the price for customers who don’t need the 25G SFP28 support. A smart, budget-friendly choice for 10G networks.

The module includes built-in digital diagnostics (DDM) for monitoring optical power, voltage, temperature, laser bias current, and other key parameters. These functions help detect abnormal activity or when customizable operating limits are exceeded. Monitoring makes it easier to plan ahead, make informed decisions, and schedule upgrades or maintenance based on real performance data.
