USL840 series 400 - 550 MHz RF-over-Fiber Transceiver
For analog and digital radio and intercom systems.
The basic model USL841-13/15 (by a distal end and a proximal end machine machine components) can achieve 1 to 1 communication.
The USL844-15 model enables multi-point communications (one machine and four proximal distal machine), and achieve a proximal end machine with up to eight Communication distal end machines.
Near and far end devices have the RF output gain adjustment, adjustable range is 32dB (1dB step). Transmission distance: a drag can reach 20KM; more than a trailer is up to 10KM. Each device has the alarm and radio alarm function.
Except the basic RF signal transmission, they also have built-in FSK transparent transmission channel, for network management, with RS232 signal transmission.

L-band Satellite 950~2150MHz RF-over-Fiber Transceiver
A set of optical transmitter and receiver work at 950~2150MHz. It converts all L-Band analog signals received by the satellite antenna tuner LNB into optical signals, and achieves high Quality, no distortion, long-distance transmission. It can be used for satellite building fiber distribution, satellite L-Band uplink/downlink.
Working frequency bandwidth (950~2150MHz), which can transmit all analog or digital signals of the entire satellite L-Band.
Transmission distance (optional 10Km, 40Km, 60Km).
Output optical power: 1mW~20mW (1310nm) for choice. Provide the industry's largest output optical power.
The optical transmitter has a built-in high linearity AGC to adapt to different levels of input positions.
The optical receiver is equipped with manual gain adjustment, which can compensate fiber loss at different distances.
The front LED provides status display and fault diagnosis.
Optical transmitter can provide +15V or +18V power supply for LNB through coaxial cable.
Strong anti-electromagnetic, radio frequency, lightning interference ability.
