1550nm TV Transmitter Externally Modulated CATV Fiber Optical Transmitter

 High Power Externally Modulated 1550nm Fiber Optical TransmitterProducts details :   Characteristic:ST1550E Optic transmitter is usually used for long-distance transmission. By ITU-T wavelength,access to a broadband PON Network is easily implemented, or applying to the FTTH Solution byWDM Technologies.Narrow bandwidth (Typ=1MHz), Lower noise, DFB continuous wave laser.Unique innovation technology; Providing excellent CNR, CTB, CSO, SBS.ITU standard wavelength is adjustable. Users can adjust and set the laser wavelength on thefront-panel with ±0.05nm stepping in the range of ±200GHz (±1.6nm), while executing networkupgrading and WDM System Expansion.AGC/MGC Mode is optional at spot; OMI can be optimized at spot.Perfect RS232 communications interface.SNMP network management optional.1+1 backup power supply optional.Excellent P/P ratio.Specifications:PerformanceIndexSupplementOptic featureLaser wavelengthnm1550±10Accordable with ITU-TG.692 StandardLinearity widthMHz≤1λEquivalent noise   intensitydB/Hz≤-160RIN 20~1000MHzOutput powerdBm2×72×5,2×9,1×7,1×5Return lossdB≥60 Optic fiber connector FC/APCSC/APC or E-2000RF featureWork bandwidthMHz45-862 Input leveldBmV18~28AGCFlatnessdB≤±0.7545~862MHzReturn lossdB>1645~750MHzInput impedanceΩ75 Link featureTransmit channel PAL-D/60ch CNR 1dB≥53.510Km optic fiber,0dBm receiveCNR 2dB≥52 CTBdB≤-65 CSOdB≤-60  SBS restrain dBm≥16.0 13,16,18 fixed or adjustable optionalGeneral featureNetwork interface port RJ45,R232Support I.E. & SNMPPower supplyV90~265 city power-48VDC optionalPower ConsumeW≤50Single power worksWork temp.°C-5~65Machine temp controlled automaticallyStorage temp.°C-40~85 Work relative temp.%5~95 Size"19×14.5×1.75WxDxH   /* 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
