1972.0. "DEFPA-DA FDDI leds specifications." by MQOOA::LEDOUX (Vincent -- DTN 632-7908) Tue Mar 05 1996 15:39

    Where can I get precise data on the FDDI leds (and receiver)
    for the DEFPA-DA?  ie: power emited, amount of light to receive
    etc...
    
    I know it uses "SC" type connectors and it uses multi-mode
    fiber, but I need more than that. 
    
    This is for a military installation and they will use
    "their" fiber to make up the connections.
    
    I assume there must be some standard these NICs adhere to, but
    can someone give me a pointer?  
    
    
    Thanks,
    
    Vince.

     Subject:  Optical Power Detail Budgets for FDDI products

     Our DEFPA optical tranceivers meet the ANSI PMD requirements.
     The optical power budgets for FDDI Products are as follows:


     Multimode:

     	Transmitter Minimum Optical Power:	-20 dBm
     	Transmitter Maximum Optical Power:	-14 dBm

     	Receiver Minimum Sensitivity:		-31 dBm
     	Receiver Maximum Optical Input Power:	-14 dBm

        Resultant Optical Power Budget =       0 to 11 dB.
