Product Name: CATV Laser 1550nm Direct Modulation Optical Transmitter with Double Power Switch Model NO.: ST1550I Condition: New Certification: CE, ISO Type: Fiber Transceiver Optical Audio Transmitter Application: Hfc, CATV, FTTX Fiber Optical Transmitterswavelength: 1550nm Network Interface Port: RJ45 RS232 Power Supply: 90-265V AC or 48VDC Optional Fiber Optical Transmitters Color: Black Optic Fiber Connector: FC/APC, Sc/APC or E-2000 Trademark: SOFTEL Transport Package: Standard Export Package Specification: 55x55x14cm Origin: Zhejiang, China Product Description CATV Laser 1550nm Direct Modulation Optical Transmitter with Double Power SwitchSummary1550nm Internal Modulation Optical Transmitter has been widely used in the applications of themulti- channel transmission. When the laser's chirp effect is reacting to the link dispersion of thefiber, there will be distortion on the receivers. While working with the EDFA, there will be seriousCSO deterioration. The distortion and deterioration will increase with the distance getting longerand channels getting more. This series of 1550nm internal modulation CATV optical transmitter haschirp and dispersion compensation inside, which makes the system index perform excellently. Itcan be used as a transition solution, such as a town where the fund is in shortage and the areacoverage is less than 10Km.CharacteristicLaser OMI AGC/MGCDual power supply inside backup.Low chirp effect, high linearity DFB laserIntuitional modulation status displayDual Module therefore drive, chirp compensationFull-automatically swicthFull-automatically control of casing temperatureParametersPerformanceIndexSupplementOptic featureLaser wavelengthnm1550±10Linearity widthMHz≤1λEquivalent noise intensitydB/Hz≤-160RIN 20~1000MHzSide mode suppression ratiodB≥35SMSRExtinction ratiodB≥20XpOutput powerdBm2×71×7,1×10,2×6,2×7SBS restraindBm≥17Return lossdB≥60Optic fiber connectorFC/APCSC/APC or E-2000RF featureWork bandwidthMHz45-862Input leveldBmV18~28AGCFlatnessdB≤±0.7545~862MHzReturn lossdB>1645~750MHzInput impedanceΩ75link featureTransmit channelPAL-D/60chCNRdB≥5110Km optic fiber,0dBm receiveCTBdB≤-65CSOdB≤-60General featureNetwork interface portRJ45,R232Support I.E. & SNMPPower supplyV90~265 city power-48VDC optionalPower ConsumeW≤50Single power worksWork temp.°C-5~65Machine temp controlled automaticallyStorage temp.°C-40~85Work relative temp.%5~95Size"19×10×1.75WxDxHCompany informationShipping & PackageCustomer feedbackFAQ1.
