Parts of the optical routing system

The optical routing system includes the following parts:

•Gigabit interface converters (CWDM GBICs)

•Optical add/drop multiplexers (CWDM OADMs)

•Optical multiplexer/demultiplexers (CWDM OMUXs)

•Optical shelf to house the multiplexers

Table 1 shows the parts of the optical routing system, and the color matching used to distinguish the eight wavelengths.

Gigabit interface converter description

Nortel Networks* coarse wavelength division multiplexed Gigabit Interface Converters (Figure 2) convert signals in a switch to laser light for connection to a fiber optic network. A CWDM GBIC transmits and receives optical signals at one of eight specific wavelengths.

Nortel CWDM GBICs use Avalanche Photodiode (APD) technology to improve transmission distance and optical link budget.
