Chapter 6: Optical routing design

Use the Avaya optical routing system to maximize bandwidth on a single optical fiber. This section
provides optical routing system information that you can use to help design your network.

Optical routing system components

The Avaya optical routing system uses coarse wavelength division multiplexing (CWDM) in a grid of
eight optical wavelengths. CWDM Small Form Factor Pluggable (SFP) and Small Form Factor
Pluggable Plus (SFP+) transceivers transmit optical signals from Gigabit Ethernet ports to
multiplexers in a passive optical shelf.
Multiplexers combine multiple wavelengths traveling on different fibers onto a single fiber. At the
receiver end of the link, demultiplexers separate the wavelengths and route them to different fibers,
which terminate at separate CWDM devices.
Important:
The Avaya Ethernet Routing Switch 8800/8600 switch no longer supports CWDM Gigabit
Interface Converters (GBIC).
The following figure shows multiplexer and demultiplexer operations.
Important:
For clarity, the following figure shows a single fiber link with signals traveling in one direction
only. A duplex connection requires communication in the reverse direction as well.
