摘要

Passive optical network and transmission method in passive optical networks. Passive optical network (200) for the transmission/reception of digital contents provided by an operator offering a set of digital contents, comprising: an optical line terminator equipment (202) connected to an ip network (224) and a multiplexer equipment/demultiplexer in wavelength (208); transmission equipment (206) on distribution lambda configured to transmit, on an optical carrier around 1550 nm, digital contents provided by said ip network (224) to an optical or electrical input port, where said optical output port is connected to said multiplexer/demultiplexer equipment in wavelength (208), in turn configured to add on a single optical fiber (209) the optical signals coming from the optical line terminator equipment (202) and the transmission equipment (206) ); optical network terminals (210) configured to make digital content requests to said optical line terminator (202) on an optical channel and to receive said digital contents; a fiber optic distribution network (209). The transmitting equipment (208) is configured to distribute said digital contents in multicast mode. (Machine-translation by Google Translate, not legally binding)
