CyberSWITCH CSX400 and CSX400-DC Installation Guide

The EPIM-F3 supports Single Mode Fiber Optic cabling. It has an internal Cabletron Systems 
FOT-F Fiber Optic Transceiver and is equipped with ST Connectors.

Transmitter Power decreases as temperatures rise and increases as temperatures fall. 
Use the Output Power Coefficient to calculate increased or decreased power output for 
your operating environment. For example, the typical power output at 25°C is 
-16.4 dBm. For a 4°C temperature increase, multiply the typical coefficient (-0.15 dBm) 
by four and add the result to typical output power (4 x -0.15 dBm + -16.4 = -17.0).

The transmitter power levels given above are Peak Power Levels after optical 
overshoot. You must use a Peak Power Meter to correctly compare the values given 
above to those measured on any particular port. If you are measuring power levels with 
an Average Power Meter, add 3 dBm to the average power measurement to correctly 
compare the average power values measured to the values listed above (i.e., -33.5 
dBm average + 3 dB = -30.5 dBm peak).
