Professional Overview

The MikroTik HS-31DLC20D is an industrial-grade SFP transceiver module built for long-distance single-mode fibre links of up to 20 km. It operates at the widely deployed 1310 nm wavelength over 9/125 µm single-mode fibre and terminates in a standard duplex LC connector for full-duplex operation. Its dual-rate 1G/2.5G design makes it a versatile fit for backbone links, campus networks, industrial deployments and ISP infrastructure.

Compared with the popular 1G S-31DLC20D, the HS-31DLC20D adds 2.5G support at the same affordable price, giving operators a straightforward path to additional bandwidth while preserving their existing single-mode fibre plant. The transmitter delivers an output power of −5 to 0 dBm and the receiver offers sensitivity down to −20 dBm (OMA), providing the optical budget needed to reach the full 20 km span reliably.

Built-in Digital Diagnostics Monitoring (DDM) continuously reports optical transmit and receive power, supply voltage, module temperature and laser bias current. Customisable operating limits and alarm thresholds let network teams detect abnormal activity early, plan ahead and schedule maintenance or upgrades based on real performance data rather than guesswork.

With an MTBF of approximately 100,000 hours at 25°C, the HS-31DLC20D is engineered for continuous operation in demanding network environments. It is compatible with MikroTik routers and switches featuring SFP cages, as well as standard SFP-based equipment. Australian stock from ARC IP Networks.
