Extreme Networks recommends that you reserve 3 dB for losses due to cable splices, connectors, and
operating margin. Table 47 describes the cable attenuation, cable budget, and operating distance for a
variety of cable attentuation ratings for the GM-WDMi module.
A minimum of 2 dB attenuation is required to prevent saturation of the receiver.

The GM-WDMi module has the following LEDs:
•
