45 - 860 mhz CCTV / RF Optical Transceiver For Video, Audio Transmission

>This machine use Gaas devices as a preamp, into the RF pre-distortion circuit, to improve the system of CTB,CSO,C/N index.

>The machine equipped with the Microprocessor software, have real-time condition monitoring transmitter operation, digital display, fault sound and light alarm, network management and other functions.
The optical receiver guarantee a higher CNR, when to receive a lower optical power was still able to. Along with the cooler to ensure the laser in shell temperature of –20℃～+70℃ degrees still can be maintained at setting temperature.

Features:
- Independent structure, apply to 1U aluminum rack for centralized management.
- Support system bandwidth: 45-860MHz
- Use imported high linearity, low noise of DFB laser, large transmission capacity, nonlinear distortion.
- RF input automatic gain control (AGC) and manual gain control (MGC) circuit.
- A comprehensive and reliable automatic optical power control circuit (APC) and laser thermoelectric cooler temperature control circuit (ATC).
- Once the laser’s operating parameters deviate from the permissible range set by the software, it will automatically disconnect the laser power and red light flashes.
- Support video lossless regenerative relay, so that video transmission up to 100km.
- Power and fiber-optic link, data status indicators of the LED can monitor system health.
- Industrial design, modular design allows reliable and flexible equipment.
