1. Product 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.

2. Performance Characteristics
  • High response PIN photoelectric conversion tube.
  • Optimized circuit design, SMT process production, optimized signal path, make the photoelectric signal transmission more smooth.
  • Specialized RF attenuation chip, with good RF attenuation and equilibrium linear, high accuracy.
  • GaAs amplifier device, power doubler output, with high gain and low distortion.
  • Single Chip Microcomputer (SCM) control equipment working, LCD display the parameters, convenience and intuitive operation, and stable performance.
  • Excellent AGC performance, when the input optical power range is -9~+2dBm, the output level keep unchanged, CTB and CSO basically unchanged.
  • Reserved data communication interface, can connect with the Ethernet transponder, access to network management system.
  • Return emission can select burst mode to sharply decrease the noise convergence and reduce the forepart receiver number.
  • ONU module optional. 

3. Technique Parameter

3.1 Link testing conditions
The technique parameters of this manual according to the measuring method of GY/T 194-2003 <Specifications and methods of measurement on optical node used in CATV systems>, and tested in the following conditions.
Testing conditions:
  1. Forward optical receive part: with 10km standard optical fiber, passive optical attenuator and standard optical transmitter composed the testing link. Set 59 PAL-D analog TV channel signal at range of 45/ 87MHz~550MHz  under the specified link loss. Transmit digital modulated signal at the range of 550MHz~862/1003MHz , the digital modulated signal level (in 8 MHz  bandwidth) is 10dB  lower than analog signal carrier level. When the input optical power of optical receiver is - 1 dBm , the RF output level is 108dBμV , with 8 dB  output tilt, measure the C/CTB , C/CSO  and C/N .
  2. Backward optical transmit part: Link flatness and NPR  dynamic range are the link indexes which is composed of backward optical transmitter and backward optical receiver.
Note : When the rated output level is the system full configuration and the receiving optical power is - 1 dBm , equipment meets the maximum output level of link index. When the system configuration reduce (that is, actual transmission channels reduce), the output level of equipment will be increased.
Friendly Notice : Suggest you setting the RF signal to 6 ~ 9 dB  tilt output in the practical engineering application to improve the nonlinear index (behind the node) of the cable system.
