CATV Fttc High Output Level Outdoor Optical Node Receiver Wr1004n-Hjs

1. Product SummaryWR-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 CharacteristicsForward 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 Parameter3.1 Link testing conditionsThe 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. 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.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.  3.2 Performance ParametersItemUnitPerformance ParametersForward Optical Receive PartOptical ParametersOptical AGC control rangedBm-8 ~ +2Optical return lossdB>45Optical receiving wavelengthnm1100 ~ 1600Optical connector type-FC/APC, SC/APC or specified by the userOptical fiber type-Single modeLink PerformanceC/NdB≥ 51-1dBm optical input, output level 108dBμV, EQ 8dBC/CTBdB≥ 65C/CSOdB≥ 60RF ParametersFrequency rangeMHz45/87 ~862/1003Flatness in banddB±0.75Rated output leveldBμV≥ 110Max output leveldBμV≥ 116Output return lossdB(85 ~550MHz) ≥16 / (550~1000MHz) ≥14Redundant receiver isolationdB≥75Output impedanceΩ75Electrical control EQ rangedB0~15 (1dB stepping)Electrical control ATT rangedB0~20 (1dB stepping)Reverse Optical Transmit PartOptical ParametersOptical transmit wavelengthnm1310±10, 1550±10 or specified by the userLaser type-DFB or FP laserOutput optical powermW1Optical connector type-FC/APC, SC/APC or specified by the userRF ParametersFrequency rangeMHz5 ~ 65 (or specified by the user)Flatness in banddB±0.75Input leveldBμV72~ 85Input return lossdB≥16Independent transmitter isolationdB≥60Input impedanceΩ75NPR dynamic rangedB≥15 (NPR≥30 dB)Use DFB laser≥10 (NPR≥30 dB)Use FP laser  RF Parameters of C-CMTS InterfaceCMTS_DSLevel of forward path insert portdBμV≥102CMTS_USGain of return path output portdB1±1Port ~ CMTS_US outputIsolation of forward path to CMTS_US return path output portdB≥70General PerformancePower voltageVA: AC(100~240)V;  B: AC (35~90)VFeed current throughA10Operating temperatureºC-40~+60Storage temperatureºC-40~+70Relative humidity%Max 95% no condensationConsumptionVA≤ 65Dimensionmm360 (L)×330 (W)×161 (H)ProcessCompany Profile  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
