NOTE:

 

4

 

Typical  values  based  using  DFB  laser.  Optical  attenuator  supplied  for  when  optical 
path loss is less than 3dB for PIN detector and 9dB for APD detector. 

 

 

5

 

With  WDM  option  fitted  for  combined  use  on  a  single  fibre,  optical  path  loss  is 
reduced by approximately 2dB. 

 

 

With  WDM  module  fitted,  when  operating  as  a  pair,  one  DTR-4630  must  be  fitted 
with a 1310nm laser and the other a 1550nm laser.

 

 

Due to our policy of continuing development, these specifications are subject to change without notice.
