Teltonika PR4LC21K BIDI SFP Transceiver

Teltonika PR4LC21K 1.25 Gb/s 20 km BiDi SFP Transceiver

When you need to stretch your network across longer distances or between buildings/cabinets where copper or short fibre won’t suffice, the PR4LC21K offers a plug-in SFP module tailored for the job. It supports bidirectional data transmission over a single fibre strand, simplifying installation and reducing fibre cabling costs.

Designed to integrate seamlessly with Teltonika SFP-enabled routers and switches, this module ensures compatibility and reliability. Its industrial ratings make it appropriate for use in remote sites, outdoor enclosures, campus networks, CCTV links, and any scenario where high-reliability fibre connectivity is required.
