MikroTik HS-85DLC05D SFP Module 1G/2.5G Multi-Mode 850 nm

Increasing bandwidth over existing fibre links without redesigning the optical plant is a common requirement in campus networks, industrial sites, and ISP nodes. A multi-mode SFP module that runs at both 1G and 2.5G addresses this need, allowing uplink ports or inter-switch links to be upgraded over distances of up to 550 m. HS-85DLC05D uses the 850 nm wavelength and a duplex LC connector, serving as an upgrade option for networks that need additional throughput over already installed cabling.

The module operates at 1G and 2.5G rates over multi-mode fibre, providing a migration path without replacing fibre or patch panels. Built-in digital diagnostics (DDM) monitor optical power, voltage, temperature, and laser bias current, flagging abnormal activity or breaches of configured operating limits. This data supports maintenance and upgrade planning based on real performance rather than estimates.

The standard SFP form factor and duplex LC connector ensure compatibility with switches and routers that support 850 nm SFP optics over multi-mode fibre. HS-85DLC05D carries over the functionality of the S-85DLC05D and adds 2.5G support, making it a direct replacement where higher bandwidth is required on the same infrastructure. It fits into uplink links, traffic aggregation, and inter-switch connections in mixed 1G/2.5G networks.

The module is aimed at system integrators, infrastructure engineers, and IT teams operating enterprise networks, industrial deployments, and ISP nodes. It suits uplinks between distribution and access switches, fibre links across office buildings or production halls, and capacity expansion at ISP points of presence. DDM support makes it particularly useful in environments where proactive monitoring of optical links reduces diagnostic time and schedules interventions before faults occur.
