     Laser Transmitter  
 
       
   Introduction  
 
   HZD-8610 CATV optical transmitter is used at hea-
 dend of new generation CATV system. It can compare
 favorably with the same transmitter abroad by using
 high function DFB laser and GaAs module with best
 flatness and other high quality index. It applys
 functions of warning and monitoring working situa-
 tion by a microprocessor.Working specification can
 be read by a light VFD vacuum fluorescent screen.
 RS232 interface in it for network management and
 remote monitoring convenience.
    Features  
19″IU standard box, good-looking and reasonable
  design.
Bandwidth of 47-860MHz.
Using high function DFB laser from ORTEL company.
Using Philips gallium arsenide head amplified m-
  odule.
Imported bright vacuum fluorescent screen for I-
  ndicating.
Immediately monitoring the working situation by
  inserting a microprocessor.
220V high function switch power supply.
Providing interface of RS232 for network manage-
  ment and remote monitoring.
Inserting AGC RF controlling circuit for its no-
  rmally working in range of 75-85 dBuV RF input
  level.
Excellent linearity.
