MikroTik 1.25G Bidirectional Single-Mode SFP Module Pair, 80km, LC, DDM

The MikroTik S-4554LC80D is a high-performance pair of single-mode SFP modules designed for reliable long-distance fiber links up to 80 km. The set includes one S-45LC80D module (Tx 1490 nm / Rx 1550 nm) and one S-54LC80D module (Tx 1550 nm / Rx 1490 nm), enabling bidirectional communication over a single fiber strand. Each module supports data rates of 1.25 Gbps, features LC connectors, and provides Digital Diagnostic Monitoring (DDM) for real-time monitoring of parameters like temperature and optical power. Compatible with all MikroTik devices equipped with SFP or SFP+ cages, this pair is ideal for building cost-effective, long-range network links.

The S-4554LC80D modules are designed to perform flawlessly even in harsh and demanding environments, thanks to their industrial-grade temperature tolerance from -40°C to +85°C. This makes them suitable for deployments where temperature fluctuations are a concern. The compact design with LC connectors ensures easy integration into existing fiber infrastructure. With full compatibility across MikroTik routers, switches, and other devices, this SFP pair simplifies deployment and ensures stable, high-speed connectivity even in challenging conditions. Perfect for ISPs, enterprises, and critical infrastructure projects requiring robust, long-distance fiber links.
