Abstract: A timing interface module installs within a rack to increase bandwidth. The timing interface module receives a reference timing signal and outputs the reference timing signal to an optical multiplexer. The optical multiplexer also receives multiple data streams of different formats, and the optical multiplexer synchronizes the multiple data streams to the reference timing signal.

Abstract: Systems, methods, and computer-readable media for propagating a timing signal over a Dense Wave Division Multiplexer fiber optic network by polarity modulation of the Optical Service Channel are provided. The systems, methods, and computer-readable media may make the timing signal available for use by devices that require a reference timing source.

Abstract: A timing interface module with daughter timing reference modules. The timing modules are provided in a rack platform to eliminate routing problems and which is compliant with all relevant industry standards. The timing reference module includes a face plate having first and second substantially rectangular openings, the face plate further comprising mounting slots for receiving mounting hardware therein and first and second timing modules, the first and second timing modules disposed within the first and second substantially rectangular openings. The first and second timing modules provide timing terminations for timing reference signals for network elements of a synchronized optical network.
