VT-15XX 1550 CATV optischer Sender

VT- 15xx Indoor 1550nm CATV Optical 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 products have 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.
