CATV 1u Indoor Optical Receiver with Swicth

1. Product SummaryWR8602JDS/WR1002JDS is our new ring network self-healing 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 CharacteristicsHigh response PIN photoelectric conversion tube.Two-channel optical signal receive, mutually backup, arbitrarily set up the auto-switching conditions, also can be set to manual switching.Optimized circuit design, SMT process production, optimized signal path, make the photoelectric signal transmission more smooth.Specialized RF attenuation chip, good RF attenuation and equilibrium linear, high accuracy.GaAs amplifier device, power double output, 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.Temperature-controlled cooling fan with low noise and high reliability.Reserved data communication interface, can connect with the Ethernet transponder, access to network management system.3. Technique Parameter3.1 Link testing conditionsThe technique parameters of this manual according to the measuring method of GY/T 194-2003 , and tested in the following conditions.Testing 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 -2dBm, the RF output level is 108dBμV, with 9dB output tilt, measure the C/CTB, C/CSO and C/N. 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. 3.2 Technique ParametersItemUnitTechnical ParametersOptical ParametersReceiving Optical PowerdBm-9 ~ +2Optical Return LossdB>45Optical Receiving Wavelengthnm1100 ~ 1600Optical Connector Type FC/APC, SC/APC or specified by the userFiber Type Single ModeLink PerformanceC/NdB≥ 51 (-2dBm input)C/CTBdB≥ 67C/CSOdB≥ 63RF ParametersFrequency RangeMHz50 ~862/1003Flatness in BanddB±0.75Rated Output LeveldBμV≥ 98 (-9dBm~+2dBm)Max Output LeveldBμV≥ 104 (Output use FP-204)Output Return LossdB≥16IsolationdB≥70Output ImpedanceΩ75Electronic Control EQ RangedB0~10Electronic Control ATT RangedB0~20General PerformanceSupply VoltageVA: AC (150~265)V; B: AC (35~90)V;C: DC48VOperating TemperatureºC-40~60Storage TemperatureºC-40~65Relative Humidity%Max 95% no condensationConsumptionVA≤ 20Dimensionmm483 (L) × 345 (W) × 44 (H)Note: The forward RF parameters are tested under the condition of using GaAs 25dB double power module in the last stage.
