The MikroTik HS-31DLC20D is a high-performance 1G/2.5G SFP optical transceiver module engineered for reliable long-distance connectivity over single-mode fiber. Operating at a 1310nm wavelength with a Dual LC connector, it supports transmission distances of up to 20 kilometers, making it ideal for enterprise, ISP, campus, surveillance, and Metro Ethernet deployments.

Designed as an upgrade to traditional Gigabit fiber modules, the HS-31DLC20D supports both 1 Gigabit and 2.5 Gigabit Ethernet, allowing organizations to increase bandwidth without replacing their existing fiber infrastructure. Integrated Digital Diagnostics Monitoring (DDM) provides real-time monitoring of optical parameters including temperature, voltage, transmit power, receive power, and laser bias current, simplifying network maintenance and troubleshooting. MikroTik positions this module as an easy bandwidth upgrade for existing fiber networks.
