MikroTik SFP+ module 10G SM 10km 1310nm Dual LC-connector

Features

The S+31DLC10D is engineered for stable 10 Gbps transmission over single-mode fiber up to 10 km using the standard 1310 nm wavelength. The duplex LC connector provides independent transmit and receive paths, matching the requirements of most modern switches and routers. Built to industrial standards, the module handles prolonged operation under elevated temperatures and vibration.

Digital diagnostics monitoring (DDM) enables real-time tracking of critical parameters: laser output power, received optical power, module temperature, laser bias current, and supply voltage. These values are accessible via the standard SFP interface, allowing integration into network management systems. Continuous monitoring helps identify signal degradation or approaching threshold limits early.

Without 25G SFP28 support, the S+31DLC10D offers a cost-effective alternative to higher-speed modules while remaining fully compatible with MikroTik devices and other 10G SFP+ equipment. An MTBF of approximately 100,000 hours supports its reliability in continuous-use environments.
