摘要： The invention relates to an Ethernet-based all-optical carrier sense multiple access/collision detection apparatus and method, and more particularly, to an apparatus and method capable of checking by using mutual gain saturation whether distortion occurs in two or more optical signals due to mutual interference when the optical signals pass through a semiconductor optical amplifier (SOA) at the same time, amplifying the optical signals transmitted in the upward direction when no distortion occurs in the optical signals, and monitoring the occupation of a plurality of subscribers with respect to a common network when the plurality of subscribers want to use an optical Ethernet network. The Ethernet-based all-optical carrier sense multiple access/collision detection apparatus according to the invention includes: a plurality of optical network units (ONUs) that carry different optical signals on upstream waves λ and transmit the upstream waves λ; a power splitter (PS) that multiplexes the optical signals and transmits the multiplexed optical signals; and a central office (CO) that checks whether the multiplexed optical signals are distorted, amplifies some of the checked optical signals, returns the other optical signals, and monitors the occupation of the plurality of optical network units with respect to a common network. According to the invention, it is possible to dynamically check whether a collision between the optical signals passing through the common network occurs and whether the optical signals are successfully transmitted. Further, since the invention uses an all-optical type, the existing electric media access control (MAC) device is not needed, which results in a high-speed operation. In addition, the invention can be used for a plurality of subscribers using an inexpensive light source. Thus, the invention can be effectively used for an optical communication industry.

摘要： 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.
