Document Type and Number:
Japanese Patent JP5650866
Kind Code:
B2
Abstract:
The invention relates to a communication system in which a master station device (10) is connected to a plurality of slave station devices (20) by an optical transmission line (30) and a plurality of wavelengths are used to perform at least one of downstream communication and upstream communication. The master station device (10) includes: a control unit (11) that assigns a wavelength to be used in communication to the slave station device (20), and that generates a control signal for notifying the slave station device (20) of the assigned wavelength; and an optical transmitter (14) that transmits the control signal generated by the control unit (11) to the slave station device (20). The slave station device (20) includes an optical receiver (23) and an optical transmitter (24) that carry out communication with the master station device (10) using the wavelength based on the control signal received from the master station device (10).
