Extreme Networks Consolidated Hardware Guide 10-7
Configuring I/O Modules
Extreme Networks recommends that you reserve 3 dB for losses due to cable splices,
connectors, and operating margin. Table 10-2 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.
Software Requirements
The GM-WDMi module requires that you load ExtremeWare version 6.1.8 or later and
BootROM 6.5 or later on your switch.
Note: See “I/O Module LEDs,” on page 10-18 for information on LED activity.
Channel 4 wavelength 1555 nm 1561 nm 1567 nm
Receiver
Optical input power sensitivity -17 dBm
Optical input power maximum -1 dBm
Fiber Optic Cable

Table 10-2: GM-WDMi Maximum Transmit Distances
Cable Attenuation Cable Budget Maximum Distance
0.20 dB/km 9 dB 45 km
0.25 dB/km 9 dB 36 km
0.30 dB/km 9 dB 30 km
