Abstract:
An apparatus comprising a wavelength division multiplexer (WDM), an optical network unit (ONU) coupled to the WDM, a passive optical network (PON) data over cable service interface specification (DOCSIS) upstream proxy (PDUP) coupled to the ONU and configured to couple to a coaxial cable, and a downstream (DS) optical/electrical (O/E) converter coupled to the WDM and configured to couple to the coaxial cable. An apparatus comprising a WDM, an optical line terminal (OLT) coupled to the WDM, a cable model termination system (CMTS) coupled to the OLT via an upstream external physical (PHY) interface (UEPI), and a DOCSIS and a Quadrature Amplitude Modulation (QAM) unit coupled to the WDM and the CMTS.
