Title:
MULTICARRIER LIGHT TRANSMITTER, MULTICARRIER LIGHT RECEIVER, AND MULTICARRIER LIGHT TRANSPORT METHOD
Document Type and Number:
WIPO Patent Application WO/2015/198571
Kind Code:
A1
Abstract:
Multicarrier light transceivers each have a restricted flexibility in allocating light transport frames to light subcarriers and hence have a drawback that it is hard to configure a multicarrier light transport system having a high efficiency. Therefore, a multicarrier light transmitter of the present invention comprises: a transmission signal generation unit that incorporates a client signal into a light transport frame and then divides the light transport frame for output to a plurality of lanes; a light transport frame multiplex process unit comprising a plurality of multiplex units each of which time-division multiplexes the light transport frame inputted from a respective predetermined input lane included in the plurality of lanes and outputs a respective multiplexed light transport frame; and a light transmission unit that uses the plurality of multiplexed light transport frames to modulate the respective ones of a plurality of light subcarriers and that sends out a multicarrier light signal in which the plurality of modulated light subcarriers have been multiplexed.
