The GM-WDMi module has one 4 Gbps port, which supports four full-duplex Gigabit Ethernet
channels. The port transmits over a single mode fiber cable using wavelength division multiplexing.
The port uses an SC-APC simplex connector with a spring-loaded safety cover. APC connectors are
polished at an 8 angle to minimize loss and reflections over extended transmit distances.

The default configuration of the GM-WDMi module is as follows. The port:
• Is added to the default VLAN as untagged.
• Inherits the properties of the default VLAN (protocol type, VLANid, and so forth).
The GM-WDMi module transmits bi-directionally on the fiber cable and then multiplexes these
wavelengths over the single-mode optical fiber.
