Special  instructions:

  The  performance  parameters  of  this  manual  according  to  the 

measuring method of GY/T 184-2002 < CATV system analog optical fiber amplifier 
technical  requirements  and  measuring  method>,  and  tested  in  the  following 
conditions.   

Test  condition:

  With  standard  optical  fiber  and  standard  optical  receiver  composed 

the  test  link.  Set  59  PAL-D  analog  TV  channel  signal  at  550MHz  frequency  range 
under the specified link loss. Transmit digital modulation signal at range of 550 MHz 
~ 862MHz, the digital modulation signal level (in 8 MHz bandwidth) is  10dB lower 
than  analog  signal  carrier  level.  When  the  input  optical  power  of  optical  receiver  is 
-1dBm, measure the C/CTB, C/CSO and C/N.
