Embodiment Construction

[0042] Reference will now be made in detail to the exemplary aspects of the invention illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0043] Figure 1-4 A telecommunications module 10 is shown having features according to an example of an inventive aspect of the present disclosure. The telecommunications module 10 may also be referred to herein as a fiber optic wavelength division multiplexing (WDM) module 10 because one of the telecommunications devices housed by the module 10 is a fiber optic wavelength division multiplexer / demultiplexer. The WDM module 10 is configured to be plugged into a telecommunications chassis similar to that shown and described in U.S. Patent Application Serial No. 11 / 975,905 (filed October 22, 2007, entitled "Wavelength Division Multiplexing Module") Internally, this disclosure is hereby incorporated by reference in its entirety. As ...

Abstract

A telecommunications module includes an optical wavelength division multiplexer / demultiplexer configured to demultiplex a first optical signal input into the telecommunications module into a plurality of different wavelengths, a fiber optic splitter configured to split a second optical signal input into the telecommunication module into a plurality of optical signals, and a plurality of optical add / drop filters, each of the optical add / drop filters configured to combine one of the optical signals that has been split by the fiber optic splitter and one of the wavelengths that has been demultiplexed by the optical wavelength division multiplexer / demultiplexer into a combination output signal that is output from the telecommunications module.
