The MikroTik S-31DLC20D is a 1.25Gbps single-mode SFP transceiver designed for long-distance fiber optic networking. It supports fiber connections of up to 20km using a 1310nm wavelength and a Dual LC UPC connector. The module is suitable for extending network connectivity between buildings, switches, routers, server environments, and other network infrastructure over single-mode fiber. Built-in Digital Diagnostic Monitoring allows compatible equipment to monitor important optical operating parameters, helping network administrators identify potential link issues. The standard SFP form factor makes the S-31DLC20D easy to install in compatible SFP ports, while its broad operating temperature range makes it suitable for demanding networking environments. It is also compatible with non-MikroTik SFP equipment that meets the required standards.
