Teltonika Single-mode LC-LC 20km Fiber Optic Cable, Grey

The Teltonika 1.25 Gb/s 20 km BiDi SFP Transceiver (PR4LC21K) is a compact bi-directional module for fiber-optic networks. It transfers data at 1.25 Gbit/s over single-mode fiber. Its BiDi functionality allows transmission and reception via a single optical strand, which reduces the cabling required for a link. The module supports distances up to 20 km and complies with the ITU-T G.652 standard for single-mode fiber. It is intended for access, aggregation, and industrial network segments that require stable gigabit links.

The module is housed in a grey metal casing, which provides integrated EMI shielding. It includes built-in electrostatic discharge (ESD) protection to safeguard the hardware during handling and operation. The transceiver features a standard LC optical interface for connection to fiber patch cables. Power consumption is at most 0.8 W during active operation. These modules are sold in pairs to facilitate a complete bi-directional link. The unit is RoHS compliant, meeting environmental safety requirements for electronic materials.
