The Teltonika PR4LC21K is an excellent two-way (BiDi) SFP transceiver operating at data rate of 1.25 Gb/s. It is specifically designed for single-mode fiber (SMF) connections, enabling efficient communication over distances of up to 20 km.

Utilizing wavelength division multiplexing (WDM) technology, this unit minimizes cabling costs while ensuring reliable performance. Key features of the Teltonika PR4LC21K include:

• Maximum transmission distance: Capable of covering 20 km over G.652 single-mode optical fiber.
• Socket type: Simplex LC, ensuring easy integration.
• Power consumption: Maximum power usage.
• Temperature tolerance: Operates efficiently between -40°C and +85°C.

Additionally, this unit features a fully metallic housing that offers low electromagnetic interference (EMI) and excellent electrostatic discharge (ESD) protection. This makes it not only durable but also compliant with RoHS and REACH standards, ensuring environmental safety.

In summary, the Teltonika PR4LC21K transceiver is an ideal solution for extending networks between buildings where traditional copper cabling or short-range optical fiber solutions may be insufficient.
