S+31DLC10D: 10G SFP+ Module, LC Duplex Connector, 1310 nm, Single-mode, 1G, 10G, 10 km

The 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 perfect for backbone links, campus networks, industrial installations, and ISP infrastructures.

This new model offers all the essential features of our well-regarded XS+31LC10D but at nearly half the price for customers who do not require 25G SFP28 support. A smart and economical choice for 10G networks. The module includes integrated digital diagnostics monitoring (DDM) for optical power, voltage, temperature, laser bias current, and other key parameters. These functions help detect abnormal activities or exceedance of customizable operating limits. Monitoring simplifies advance planning, enables informed decisions, and schedules upgrades or maintenance based on real performance data.
