The MikroTik S-85DLC05D is an industrial-grade 1.25G Multi-Mode SFP optical transceiver engineered for high-speed local area networks, enterprise building interconnects, and data center fiber aggregation. Operating over standard multi-mode OM2/OM3/OM4 fiber optics at an 850nm VCSEL wavelength, it provides high-throughput transmission over distances up to 550 meters with minimal latency.
Equipped with a Dual LC connector interface, the module supports full Digital Diagnostic Monitoring (DDM / DOM), allowing network administrators to monitor critical operational metrics in real time through RouterOS or network management platforms. Housed in a compact, hot-swappable metallic casing, the S-85DLC05D is fully compliant with MSA (Multi-Source Agreement) standards and IEEE 802.3z 1000BASE-SX specifications, ensuring seamless plug-and-play interoperability across MikroTik routers, switches, and third-party network gear.
