    Area of Science:

    • Optical networking
    • Signal processing

    Background:

    • Multiple reflections degrade signal quality in distance-multiplexed all-optical passive tree networks.
    • Existing reflection cancellation methods, like Faraday rotators, can be complex to implement.

    Purpose of the Study:

    • To introduce a new, simpler method for canceling multiple reflections.
    • To address signal integrity challenges in all-optical networks.

    Main Methods:

    • Development of the temporal orthogonalization technique.
    • Application of temporal orthogonalization within network nodes.

    Main Results:

    • Successful cancellation of multiple reflections in the studied network architecture.
    • Demonstration of a simpler implementation compared to Faraday rotator-based methods.

    Conclusions:

    • Temporal orthogonalization provides an effective and simpler solution for reflection cancellation.
    • This method enhances the feasibility of all-optical passive tree networks.
