HS-85DLC05D is a reliable, industrial-grade 1G/2.5G SFP module designed for multi-mode fiber links up to 550 m. It uses the widely supported 850 nm wavelength and an LC connector, making it a practical choice for enterprise networks, industrial deployments, and ISP infrastructure.


This new model delivers all the essential features of our popular S-85DLC05D, but now with 2.5G support at the same affordable price. A simple and cost-effective upgrade for networks that need more bandwidth without changing their existing fiber infrastructure.


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.
