Abstract: Provided are extendable loop-back passive optical network (PON) and scheduling method and apparatus for the same. The loop-back type PON includes an OLT (optical line terminal) including a wavelength-tunable optical transmitter and a wavelength-locked optical receiver, and an RN (remote node) including an optical coupler/splitter, the optical coupler/splitter receiving optical signals from the wavelength-tunable optical transmitter and splitting the optical signals by wavelength so as to transmit the optical signals to corresponding ONTs (optical network terminals). Each of the ONTs transmits upstream data to the OLT using the same wavelength as the wavelength of the optical signal received from the OLT through the RN. Since the optical network makes use of the TDM and WDM communication schemes, the optical network can be maintained and upgraded at lower cost.

Abstract: Provided is a method of increasing the number of subscribers using a time division duplexing (TDD) technology in a wavelength division multiplexing (WDM)/Ethernet passive optical network (WE-PON) system, and more particularly, a method of increasing the number of subscribers admissible per wavelength using a TDD technology. In an existing WE-PON, due to an amplitude squeezing effect (ASE) in an optical network terminal (ONT) and an optical output power restriction in an optical line terminal (OLT), there is a disadvantage in that 4 or more subscribers cannot be simultaneously accommodated per wavelength. However, the present invention enables accommodation of a maximum of 16 subscribers per wavelength by applying a TDD technology to a medium access control (MAC) protocol.

A PCS layer transmits and allocates wavelength information such that wavelengths for setting a link between an OLT and an ONT are allocated, optical wavelengths within the ONT are observed while a system operates to allow continuous control so that operating of the system can be stably maintained.
