We are looking for the values for Transmit launch signals and Receive input signals for FDDI fiber MIC ports. An installer asked us this question specifically for the DECswitch 900EF. We have also been asked this several times for other products. Are the values the same for all FDDI MMF device ports? I have checked the 900EF FDDI port specification, the functional hardware specification, and other resources. The values will be in -dBm. Thanks! Rick Blanchette TCC Network Products Support

Subject: Optical Power Detail Budgets for FDDI products
The optical power budgets for FDDI Products are as follows:
Multimode PMD:
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.
Single-mode PMDs
Transmitter Minimum Optical Power: -8 dBm
Transmitter Maximum Optical Power: -2 dBm
Receiver Minimum Sensitivity: -30 dBm
Receiver Maximum Optical Input Power: -14 dBm
Resultant Optical Power Budget = 12 to 22 dB.
