	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. Richard Kirk Network Product Support
