1. Product Summary
WR8604DJ-1G is our new high-class 4-way output CATV network optical receiver. The pre-amplifier adopts all-GaAs MMIC, post-amplifier adopts GaAs module. Optimized circuit design coordinate with our 10 years design experience, the device achieve high performance index. Microprocessor control, digital display the parameters that make the engineering debug very convenience. It is the main products to build CATV network.
2. Performance Characteristics
  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, good RF attenuation and equilibrium linear, high accuracy.
  4. GaAs amplifier device, power doubly output, high gain and low distortion.
  5. Microprocessor control working status, digital 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, it is convenient to connect with network management transponder and access to network management system.
  8. Return emission can select burst mode to sharply decrease the noise convergence and reduce the forepart receiver number.
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 modulation signal at range of 550MHz~862/1003MHz, the digital modulation signal level (in 8 MHz bandwidth) is 10dB lower than analog signal carrier level. When the input optical power of optical receiver is -2dBm, the RF output level is 108dBμV, with 9dB 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 -2dBm, 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 6~9dB tilt output in the practical engineering application to improve the nonlinear index (under the node) of the cable system.
