Product Description
1. Product Summary
WR-1004N-HJS outdoor optical node can be configured 2 forward path optical receiver modules, 2 return path optical transmitter modules, 1 Ethernet transponder module and 2 switching power supply modules at most. Adopts advanced optical AGC technology, the output level and output slope both adopt the electric control circuit. Add LED segment display function, the forward path output signal 116dBμV.
2. Performance Characteristics
  • Forward path optical receiving part adopts advanced optical AGC technology, the input optical power range extended to -8~+2dBm.
  • Forward path optical receiving part: RF operating bandwidth extended to 1GHz, each way maximum output level up to 116dBμv.
  • Full electric adjust attenuation and equilibrium control circuit, and achieve remote operation by NMS.
  • RF amplifier part adopts quick plug modular design, can quickly replace RF amplifier module without dismantling the RF cable connector.
  • Built-in perfect condition monitoring circuit, and support Ethernet transponder.
  • Reserved C-CMTS forward path and return path RF interface, support DOCSIS EOC networking scheme.
3. Technique Parameter
3.1 Link testing conditions
The performance 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.
  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 -1dBm, the RF output level is 108dBμV, with 8dB output slope, measure the C/CTB, C/CSO and C/N.
  2. Return optical transmit part: Link flatness and NPR dynamic range are the link indexes which is composed of return path optical transmitter and optical receiver.
Note: When the rated output level is the system full configuration and the receiving optical power is -1dBm, equipment meets the maximum output level of link index. When the system configuration degrade (that is, the actual transmission channels reduce), the output level of equipment will be increased.
Friendly Notice: Suggest you setting the RF signal to 6~9dB slope output in the practical engineering application to improve the nonlinear index of the cable system.
