Abstract
An optical coupler, a communication method, and a communication system are provided. The communication system includes N transmitters, M receivers, and an optical coupler, where both N and M are positive integers greater than 1. Each of the N transmitters is configured to send one first optical signal to the optical coupler. The optical coupler is configured to couple N first optical signals sent by the N transmitters into one second optical signal and to broadcast the second optical signal to the M receivers. Each of the M receivers is configured to receive the second optical signal sent by the optical coupler and to demodulate the second optical signal.
Claims20
A communication system, comprising:
- N transmitters, M receivers, and an optical coupler, wherein both N and M are positive integers greater than 1, and wherein:
- each of the N transmitters is configured to send one first optical signal to the optical coupler;
- the optical coupler is configured to couple N first optical signals sent by the N transmitters into one second optical signal and to broadcast the second optical signal to the M receivers;
- and
- each of the M receivers is configured to receive the second optical signal sent by the optical coupler and to demodulate the second optical signal.
An optical coupler, comprising:
- a coupling structure configured to be connected to N transmitters through an optical fiber and to couple N first optical signals sent by the N transmitters into one second optical signal, wherein N is a positive integer greater than 1;
- and
- a broadcast structure configured to be connected to M receivers through an optical fiber and to broadcast the second optical signal to the M receivers, wherein M is a positive integer greater than 1.
A communication method, comprising:
- sending, by each of N transmitters, one first optical signal to an optical coupler, wherein N is a positive integer greater than 1;
- coupling, by the optical coupler, N first optical signals sent by the N transmitters into one second optical signal and broadcasting the second optical signal to M receivers, wherein M is a positive integer greater than 1;
- and
- demodulating, by each of the M receivers, the second optical signal received from the optical coupler.
