Teltonika PR4LC21K SFP Transceiver — 1.25Gb 20KM

The Teltonika PR4LC21K BiDi SFP Transceiver delivers reliable long-distance fiber connectivity with 1.25 Gb/s data transmission speeds over distances up to 20 kilometers. This bidirectional (BiDi) transceiver uses a single fiber strand to simultaneously transmit and receive data, reducing fiber infrastructure costs while maintaining professional-grade performance. Designed as an accessory for Teltonika’s industrial networking equipment and compatible with standard SFP ports, this module provides a cost-effective solution for extending network connectivity across campuses, between buildings, or in remote deployment scenarios where running multiple fiber strands isn’t practical.

• 20KM transmission range enables long-distance connectivity without signal degradation
• BiDi technology uses a single fiber strand, reducing cabling costs and complexity
• 1.25 Gb/s throughput supports gigabit network speeds for bandwidth-intensive applications
• Standard SFP form factor ensures compatibility with a wide range of networking equipment

This transceiver is particularly valuable for IT professionals and system integrators working on distributed network installations where fiber connectivity is essential but infrastructure costs must be controlled. The BiDi design’s ability to operate over a single fiber strand makes it ideal for upgrading existing installations or deploying new links where fiber availability is limited, while the 20-kilometer range ensures reliable connectivity for rural locations, industrial sites, or multi-building deployments that exceed the reach of standard copper or short-range fiber solutions.
