HI AABID
Thank you for replying.. I got it but can you tell me what is the minimum and maximum value of receiver sensitivity we can use for our design..I mean what actually is the permissible value of the receiver sensitivity..there must be some standard value for optical receivers upto which they are able to read signals..In optisystem 14 the default receiver sensitivity is taken as -30 dbm..and i think it might be around the standard value..
Thanks and regards
