SHELF AND WDM HOST MODULE
A bi-directional wavelength division multiplexer (WDM) system is available as an
accessory item for the Prism system.
If the Prism configuration does not require the use of a WDM system, skip this
section and proceed
to “Install Host in Equipment Rack” on page 66.
3.4.1 Wavelength Division Multiplexer System Overview
The Wavelength Division Multiplexer (WDM) system is an accessory product that is
used when it is desirable or necessary to combine the forward and reverse path
optical signals from one Prism system onto a single optical fiber. Each WDM system
consists of a Host and a Remote. At the Host there is a WDM chassis that contains the
WDM modules, and there is a WDM cable assembly within the Remote. Both the Host
WDM module and the Remote WDM cable assembly consist of a bi-directional
wavelength division multiplexer, as shown in Figure 3-4. Note that the WDM enables
up to three Prism RF bands to operate on a single OSP fiber.
