Overview
YUK1000L series L-band optical transceivers are divided into YUK1000L-T series optical transmitters and YUK1000L-R optical receivers, which are used to realize optical transmission of L-band satellite signals (satellite intermediate frequency signals). The optical transmitter outputs the high-frequency head, connects to the L-band satellite signal through the coaxial cable, and converts it into an optical signal. The optical receiver receives the optical signal sent from the optical transmitter and provides RF signal output.
The RF input of the optical transmitter can provide operating voltage to the Ku-band or C-band downconverter (satellite tuner) connected outdoors through panel control, and can complete the horizontal (H) and vertical (H) of satellite reception on this machine. V) Polarization conversion, the optical transmitter has AGC control function.
