Abstract
An optical link power management scheme takes the best advantage of a dynamic connection environment, where ports may be connected and disconnected at any time, and where data flows may start and stop as needed by the applications using the high speed data links. Power consumption is optimized, eye safety standards are met, and robust connection detection is preserved.
Claims7
A method, comprising:
- sending from an optical module periodic low speed optical pulses (LSOPs) when the optical module is disconnected for a Standby State;
- connecting the optical module to a connection port;
- sending a number of consecutive LSOPs for a Connected Standby State at a first duty cycle rate;
- sending LSOPs at a second higher duty cycle rate for a Connected Idle State;
- sending a shorter duration LSOP to initiate a Resume State;
- and
- entering an active state to transmit high speed data.
