LynxTechnik L-Band To Fibre Optic Transmitter 10km With Fibre LC Connectors

Product Code LYOTX1910
Manufacturer LynxTechnik

Request more information or contact us now for purchasing information.


The OTX 1910 is an effective solution for transporting analogue RF L-Band signals over long distances. The module supports RF signals within the extended L-Band range of 700MHz to 2300MHz.

The module is configured using the integrated dip switch. This allows the LNB power to be activated and switched to 13V or 18V to select horizontal or vertical polarization. Additionally, the internal 22kHz tone generator can be turned on and off to select the high or low frequency range.

When paired with the fibre optic receiver for RF signals (yellobrik ORX 1900) you have a very cost effective optical RF transmitter/receiver system for distances up to 10km
