Abstract
A system for providing bi-directional RF services over a point-to-multipoint Passive Optical Network (PON). A system that can transport upstream RF signals generated by devices such as a set top box or a cable modem, through a passive Optical Network while simultaneously supporting downstream RF video and bi-directional base-band services on the PON.
Claims1
A node comprising:
- an upstream port for coupling to an optical fiber carrying optical signals in a bidirectional passive optical network;
- a second upstream port for coupling a downstream optical signal to an Three-Wavelength ONU that handles a plurality of wavelengths;
- an RF optical transmitter for receiving an upstream RF signal from a diplexer and transmitting an upstream RF optical signal over the bidirectional passive optical network;
- and
- a Wavelength-Division-Multiplexer (WDM), coupled to the RF optical transmitter and the upstream port, operative to multiplex the upstream RF optical signal with other upstream optical signals onto the bidirectional passive optical network.
