WDMi Module

Figure 120 shows the WDMi module.

Figure 120: WDMi module

The WDMi module has one 10 Gbps port, which supports eight full-duplex Gigabit Ethernet channels.

The port transmits over a pair of single mode fiber cables using wavelength division multiplexing. The

port uses an SC-APC duplex 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 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 WDMi module transmits bi-directionally on both fiber cables and then multiplexes these

wavelengths over the single-mode optical fiber.

Table 65 describes the specifications for the WDMi optical interface.
