Embodiment Construction

[0019] It should be understood at the outset that although an illustrative implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of techniques, whether currently known or in existence. The invention should in no way be limited to the illustrative implementations, drawings, and techniques illustrated below, including the exemplary designs and implementations illustrated and described herein, but may be limited within the scope of the appended claims and their equivalents. Modify within the complete scope of the object.

[0020] Although TDM PON is considered a more advanced fiber optic access technology, coaxial cables are still widely used for last-mile broadband access. Coaxial cable has substantially higher bandwidth than twisted pair and has been widely adopted over the past twenty or thirty years. Due to the relatively high cost of FTTH, the full utilization of the bandwidth of existing coaxia...

Abstract

An apparatus comprising a time domain multiplexing (TDM) to Orthogonal Frequency Division Multiplexing (OFDM) or bounded Quadrature Amplitude Modulation (QAM) channels HOT PON converter configured to couple to an optical line terminal (OLT) via an optical fiber and to a plurality of network terminals (NTs) via a point-to-multipoint coaxial cable and configured to transmit TDM data from the OLT using OFDM or bounded QAM channels to the corresponding NTs, wherein the OFDM or bounded QAM channels transmission of TDM data maintains End-to-End (E2E) TDM passive optical network (PON) protocols, service provisioning, and quality of service (QoS).

Description

[0001] The present invention requires U.S. Provisional Patent Application No. 61 / 371,408 filed on August 6, 2010 by Dai Yuxin, titled "Hybrid Orthogonal Frequency Division Multiplexing Time Domain Multiplexing Passive Optical Network" and August 5, 2011 The prior application priority of the US patent application No. US13 / 204,286 filed by Yuxin Dai entitled "Hybrid Orthogonal Frequency Division Multiplexing Time Domain Multiplexing Passive Optical Network", the contents of which are cited in the manner incorporated into this text. technical field [0002] The present invention relates generally to network communications, and more particularly to passive optical networks. Background technique [0003] Over the past twenty to thirty years, coaxial cable lines have been widely deployed around the world. Although fiber-to-the-home (FTTH) architectures based on time-domain multiplexing (TDM) passive optical networks (PON) have emerged, coaxial cable lines still serve many broadba...
