Product Description

1. Product Summary
WR1001K optical receiver is the bidirectional  equipment that is specially developed for HFC structure bidirectional metropolitan area broadband network. Rely on several years' research experience for CATV HFC fiber transmitting equipment. Take full account of the FTTH (Fiber to the Home) network topology, the engineering technology problem of CATV bidirectional return channel noise collection and the high reliability network security transmission requirements of modern CATV business. The return path adopts the burst mode (open the laser when have return signal), which greatly reduced the noise collection.
 
2. Performance Characteristics

1. Laser control circuit adopts unique design, the work is reliable and stable.
2. Excellent AGC characteristic, when the input optical power range is -7~+2dBm, the output level remain unchanged, CTB and CSO basically unchanged.
3. Optimizing circuit design, SMT production process, optimizing the whole signal path, makes the photoelectronic signal transmission more stable, RF linear indicators higher.
4. Professional RF attenuator circuit, with good attenuation linear and high precision.
5. GaAs amplifier device, with good index, low distortion and high reliability.
6. The return path control adopts burst mode, which greatly reduced the noise collection.
7. The shell adopts aluminum die casting, cooling effect is good and the appearance is exquisite.
