Full-Duplex Multi-Mode Fiber Communication

摘要

Techniques are presented herein to facilitate higher bandwidth communications in a data center using existing multi-mode fibers and full-duplex optical communication techniques. A first device transmits to a second device a first optical signal at a first wavelength on a first optical fiber. The first optical signal carries a first portion of Ethernet traffic. The first device receives a second optical signal transmitted at a second wavelength on the first optical fiber from the second device. The second optical signal carries a first portion of Ethernet traffic. On a second optical fiber, the first device transmits to the second device a third optical signal at a third wavelength. The third optical signal carries a second portion of Ethernet traffic. The first device receives a fourth optical signal at a fourth wavelength on the second optical fiber, the fourth optical signal carrying a second portion of Ethernet.

1. A method comprising:
transmitting from a first device to a second device a first optical signal at a first wavelength on a first optical fiber, the first optical signal carrying a first portion of Ethernet traffic from the first device to the second device; receiving a second optical signal at a second wavelength on the first optical fiber, the second optical signal carrying a first portion of Ethernet traffic from the second device to the first device; transmitting from the first device to the second device a third optical signal at a third wavelength on a second optical fiber, the third optical signal carrying a second portion of Ethernet traffic from the first device to the second device; and receiving a fourth optical signal at a fourth wavelength on the second optical fiber, the fourth optical signal carrying a second portion of Ethernet traffic from the second device to the first device.
