Abstract
Description
technical field
[0001] The present invention relates to the field of point-to-multipoint optical network communication technology, in particular to the application of broadband value-added services in point-to-multipoint optical networks, and specifically to a method and system for realizing dynamic allocation of bandwidth resources in point-to-multipoint optical networks . Background technique
[0002] Optical network is commonly referred to as optical fiber network, and its transmission medium is optical fiber. In an ordinary network, the data signal is carried by electricity, and 0 and 1 are distinguished by the voltage level, while in an optical network, the data is carried by a laser, and the laser transmitter emits lasers of different intensities to distinguish 0 and 1. and 1. Since ordinary twisted-pair wires use electrical signals, the transmission distance is limited. For example, the theoretical maximum transmission distance of Category 5 wires is about 100 meter...
