Power management implementation in an optical link

摘要

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.

主权项

1. An apparatus to communicate over an optical link, the apparatus comprising:
an optical module to:
transmit a first set of optical pulses at a first duty cycle via the optical link; andreceive a determined number of optical pulses of a second set of optical pulses at the first duty cycle via the optical link; and a control module coupled with the optical module, the control module to:
determine that a communicative connection over the optical link is established based on the receipt of the determined number of optical pulses of the second set; andcause the optical module to transmit a third set of optical pulses at a second duty cycle via the optical link, wherein the second duty cycle is greater than the first duty cycle.
