1550nm External Modulation Transmitter is a kind of 1550nm external modulation optical wavelength signal (DFB) transmitting equipment for HFC broadband transmitting network.Using direct modulate,on the demand of low operation input RF signal level,ensures it for the front of the channel.Under 860MHz.it can transmit TV signal and INTERNET digital signal.With MPU circuit,SBS and ALC circuit to control the working status of the Laser,it will display in the LCM/VFD on the front panel,Excellent non-linear can ensure products buildup multilevel fiber net,achieve the use-rsbestrow In a distance.it also can use RS232 for distance control.Features:(1) Frequency Range: 45~862MHz.(2) RF- input level: 75dBμV~85dBμV.(3) Optical power: >7dB (2 output).(4) Predistortion Circuit and LiNbO3 makes the productshave a good Non- linear Distortion.(5) ATC/APC circuit makes the stability of the functions.(6) MCU monitor the status, LCM/VFD display the status,Customer can test parameters at any time.(7) SBS >18(SBS option :13~18, or fixed).(8) RF input point and power supply with lightning protection,ensures safety.(9) 19 inch 1U design for installation.Electric Parameter: Bandwidth 42~862MHz Flatness ±1.0dB Input Return Loss 6/14dB(550/862MHz) Input Impedance 75Ω Noise wideband 5MHz RFInputSignalLevelRange 75dBμV~85dBμV OMI/CH 3%±0.25% RF test point -20dBμV±2dBμV@input RF Connector F-connector(mm/inch) Network connector RS232/485 Power consumption < 60 watt Power Supply 220V(110 -265V/50Hz) Optical Parameter: Laser Type DFB Optical wavelength 1550±10nm Optical wideband ≤0.3 MHz Output Optical Power ≥7dBm Optical output path 2 Noise level ≤-160dB/Hz SBS suppression threshold 13~18 Optical return loss ≥45dB Optical Connector FC/APC,SC/APC Path Parameter: CNR ≥53dB C/CSO ≤-65dB C/CTB ≤-65dB Environment Parametre: Storage Temperature -20~+65 temp Humidity ≤80% Op.T.
