External Tx CATV 1550nm Fiber Optical Transmitter Price for FTTH

FWT-1550ET Series, 1550nm Top Type External Modulated Optical Transmitter Product Description FWT-1550ET series is a model of 1550nm Externally Modulated Optical Transmitter according with current international industry technique standard. The device's light source adopts narrow line width(Typ.=0.65MHz), low noise and continuous wave DFB laser, which is propitious to reduce the influence of dispersion.Adopting the LiNbO3 external modulator specially developed and produced by USA Oclaro for CATV signal modulation, and independently developed and designed dual microwave source optimization control technology, which achieves transmission of more than 120KM, CNR≥53dB, CTB≤-65dB, CSO≤-65dB, 47 ~ 862 MHz, SBS: 13-19dBm continuous adjustable. Equipped with SNMP network management, 1 + 1 power supply backup, and chassis temperature automatic control.The FWT-1550ET series transmits 1550nm externally modulated optical transmitters over long distances, transmitting CATV signals in all bands, especially ensuring low-frequency and high-quality signals. With its high indicators, high reliability, and excellent performance-price ratio, it is suitable for large and medium-sized CATV station's headend, which then used for the trunk and distribution network trunk.Product feature1. Top quality: The original dual microwave source innovation technology and RF predistortion technology ensure the system has the perfect CTB, CSO and SBS indexes when CNR≥53dB.2. Flexibility: The phase modulation technology of the external modulator maximizes the optical power of the fiber to obtain long-haul transmission while ensuring the excellent CSO performance of the system, and the SBS threshold is continuous adjustable: 13-19 dBm; AGC / MGC mode selectable at site, OMI can be adjustable, suitable for different network transmissions.3. Suitable for long-haul transmission of backbone networks and metropolitan area networks.4. High bandwidth: up to 47-1000MHz working bandwidth.5. Reliability: 19" 1U standard rack, built-in high-performance 1 + 1 hot backup power supply, which can work at 86 ~ 265Vac city network. MS automatic switching, and chassis temperature automatic control.6. Intuitive: The external modulator and laser are the most expensive components of the device. The built-in microprocessor monitors the external modulator and laser working status, and the working parameters are displayed on LCD.7. Network management type: SNMP network management, can realize the network management WEB monitoring function.8. Passed EMC and LVD international standard CE certification.Technical ParametersItemsUnitParameterNoteLaser Model DFBOclaro (Made in USA)Wavelengthnm1550±10Specified Before OrderingOptical Modulation Method Externally Modulated Optical Output PowerdBm2x7Can Customize 2x8, 2x9,2x10SBS ThresholddBm19(Default)13~19 continuous adj.Optical Connector FC/APC or SC/APCSpecified Before OrderingFrequency RangeMHz47~1000 CNRdB≥53.0GY/T143-2000 6.2.3.5FlatnessdB±0.75GY/T143-2000 6.2.4RF Input LeveldBuV78~88AGC Automatic ControlC/CTBdB≥65.0GY/T143-2000 6.2.5C/CSOdB≥65.0GY/T143-2000 6.2.6RF Input ImpedanceΩ75 RF Input Return LossdB>16(47~550)MHz>14(550~862)MHzGB/T11381.1 4.2.2.2.5Power SupplyV90~265 VACOptional -48VDCPower ConsumptionW≤50Single Power Supply OperationWorking TemperatureºC0~50Automatic Temperature ControlStorage TemperatureºC-20~85 Working Relative Humidity%20%~85% Dimension″19″×11″×1.75″483(W)x280(D)x44(H)Network Management Interface RJ45Supporting Web Browser and SNMPProduct model seriesFWT-1550ET -2×7 (two outputs, ≥7dBm)                       FWT-1550ET -2×8 (two outputs, ≥8dBm)                        FWT-1550ET -2×9 (two outputs, ≥9dBm)FWT-1550ET -2×10(two outputs, ≥10dBm)                                                 Main technical indicatorsItemsParameterRemarkOptic  ParametersOperating wavelength(nm)1550±10 Output power(dBm)2×102×7, 2×8, 2×9 ,2×10 , 2×11, 2x12Return loss(dB)≥52 Optical fiber connector SC/APCOptional SC/APC,FC/APCRF  ParametersBandwidth(MHz)47~860 or 47~1080 Input level(dBmV)23±5AGCFlatness(dB)≤±0.7545~(862)1080MHzReturn loss(dB)>1645~750MHzInput Impedance(Ω)75 Link  ParametersChannels PAL-D/60ch CNR(dB)≥5365Km fiber, Receive 0dBmCTB(dB)≤-65 CSO(dB)≤-65 SBS(dB)≥16.013~19dB adj.General  ParametersNM interface RJ45 Power(V)90~265Optional -48VDCPower consumption(W)≤50 Working Temp(ºC)0~50Automatically casing temp controlStorage Temp(ºC)-20~85 Operating relative humidity(%)5~95 Size(")19×14.5×1.75(W)x(D)x(H)Products seriesFWT-1550ET -2×7    (two outputs, ≥7dBm)FWT-1550ET -2×8    (two outputs, ≥8dBm)FWT-1550ET -2×9    (two outputs, ≥9dBm)  FWT-1550ET -2×10    (two outputs, ≥10dBm)FWT-1550ET -2×11    (two outputs, ≥11dBm)FWT-1550ET -2×12    (two outputs, ≥12dBm)If you have another question, please feel free to contact me directly as below:Hangzhou Fullwell Optoelectronic Equipment Co., LtdAdd:A2-1305,Qimeng Science & Innovation Park,No.1899,Gudun Road,Hangzhou, ChinaContact person: Leo Yao "Design and manufacture
