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.

Abstract: The present invention provides an apparatus and method for preserving a frame sequence and distributing traffic in a multi-channel link, which efficiently distributes frame traffic while preserving the transmission sequence of frames in a link composed of multiple channels, and to a multi-channel transmitter using the apparatus and method. The present invention determines whether the preservation of a sequence of frames is required using information about received frames, predicts a frame transmission service finish time on the basis of the length of frames if the sequence preservation is required, determines a sequence preservation service time (SPST) on the basis of the predicted transmission service finish time, stores the frames in a sequence preservation buffer for the SPST, and distributes the frames to idle transmitters at a termination point of the SPST, thus maximizing the efficiency of channel use.

Abstract: The present provides a method of dynamically managing multicast groups and allocating multicast service wavelengths for the highest channel efficiency. According to the present invention, the share indices of wavelengths of all multicast service groups, which employ broadcasting wavelengths and data wavelengths, are periodically ascertained on the basis of IGMP snooping-based technology in a WDM-PON. Based on the ascertainment results, if the channel share index of the group that employs the broadcasting wavelength is smaller than the channel share index of the group that employs the data wavelength, the share index of the wavelength of the multicast group that employs the broadcasting wavelength is maximized by dynamically changing allocation of the wavelength of the multicast group, so that a maximum multicast service can be provided within limited resources.
