Description

1) RF: the RF input signal through the optical transmitter on the rear panel of the "RF / IN" connector input. Input signal is amplified to meet the needs of the driver laser level. 2) 2) Laser control circuit: This circuit is used to control the laser temperature, bias current and the signals, to obtain a stable optical power output. 3) Pre-distortion correction circuit: to facilitate long-distance transmission. 4) Network management circuit: optical transmitter microprocessor also provides communication interface, set the rear panel RS ***2 **5 computer industry standard interfaces and Internet port for network management and remote monitoring use. CATV addressable charge management system Nonlinear Editing System 5) Meet GY/T*******0 "cable television system of laser transmitter and receiver AM network technical conditions and methods of measurement" standard category A requirements of laser transmitter;
