Abstract
High-speed optical communication is very attractive to satisfy high throughput applications. In the meanwhile, it is also desirable to reduce the energy waste resulted from an idle state of the optical transceivers of the communication system. The present invention discloses that both the access point () and the end point device () can operate in at least two different operation states, a normal operation state and a low power state. The low power state is a default state, and the normal operation state is enabled only when a valid trigger is detected. To establish a high-speed optical link (), the end point device () first sends an optical trigger signal () to the access point () in the low power state. The access pint () switches to the normal operation state only when a valid trigger signal is identified after detecting the optical trigger signal ().
