Title:
MASTER STATION DEVICE, CONTROL DEVICE, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/022807
Kind Code:
A1
Abstract:
The present invention solves the problem of providing a master station device capable of reducing the time required for resuming normal data transmission/reception after the occurrence of a change in wavelength. The present invention is a master station device (OLT1) that accommodates one or more slave station devices (ONU101, 102, …, 109) and allocates one wavelength selected from among multiple candidates to each slave station device in order to communicate with the slave station devices. When a slave station device that requires a change in the used wavelength , the master station device instructs the slave station device to change the wavelength and causes the slave station device to notify terminal devices under the slave station device of the address of the slave station device.
