1.25 Gbit SFP BiDi, 1310nmTX/1550nmRX, 20km, LC-Simplex, Singlemode, Set of 2
The Teltonika PR4LC21K is a matched pair of bidirectional SFP transceivers supporting data transmission at up to 1.25 Gb/s. Both modules feature a simplex LC interface and support link distances of up to 20 km over G.652 single-mode fibre. The first transceiver operates with a 1310 nm transmit and 1550 nm receive wavelength, while the complementary module transmits at 1550 nm and receives at 1310 nm.
Power consumption remains below 0.8 W per module. An extended operating temperature range from −40°C to +85°C supports deployment in demanding professional environments. Fully metallic enclosures help minimise electromagnetic interference and provide enhanced protection against electrostatic discharge. The transceivers are RoHS and REACH compliant and specified for operating humidity levels from 5 to 85%.

The Teltonika PR4LC21K is designed to establish bidirectional fibre links between two compatible network devices equipped with SFP slots. BiDi technology transmits and receives data at different wavelengths over the same single-mode fibre, allowing an existing single-fibre connection to support a full point-to-point network link.
Typical applications include inter-building connections, campus networks, industrial sites, remote technical rooms and distributed network infrastructure. A transmission distance of up to 20 km supports connections between geographically separated switches and other network components. Host-device SFP compatibility and the use of suitable G.652 single-mode fibre should be verified before deployment.
