Summary
WR1002JLED is a new modular two-output CATV network optical receiver. It adopts modular design,
use more flexible.
Microprocessor control, digital display the parameters, the engineering debug is especially easy.
It is the main equipment to build the CATV network.
Features
1. High response PIN photoelectric conversion tube.
2. Optimized circuit design, SMT process production, optimized signal path, make the photoelectric
signal transmission more smooth.
3. Specialized RF attenuation chip, with good RF attenuation and equilibrium linear, high accuracy.
4. GaAs amplifier device, power doubler output, with high gain and low distortion.
5. Single Chip Microcomputer (SCM) control equipment working, LCD display the parameters,
convenience and intuitive operation, and stable performance.
6. Excellent AGC performance, when the input optical power range is -9~+2dBm, the output level
keep unchanged, CTB and CSO basically unchanged.
7. Reserved data communication interface, can connect with the Ethernet transponder, access to
network management system.
8. Return emission can select burst mode to sharply decrease the noise convergence and
reduce the forepart receiver number.
9. ONU module optional.
