1572.1ANSI PMD ConformantNPSS::KIRKFri Feb 03 1995 08:5314
    We conform to the requirements of the ANSI MMF PMD Specification.
    
    	Transmitter Output Power =  -14 dBm MAX to -20 dBm Minimum
    
    	Receiver Sensitivity     =  -14 dBm max to  -31 dBm minimum
    
    The minimum level combine to give the 11 dB budget for FDDI. The
    maximum levels are set so that the transmitter can not overdrive the
    receiver.
