Understanding and optimising transceiver efficiency using internal metrics for improved power savings#

Speakers: not listed in the program.

• Why: Transceiver power is becoming a first-order constraint in DC design (often a large fraction of a port's total power budget), and a talk about driving savings from internal transceiver metrics — not vendor datasheets — is exactly the operational, measurement-driven optics content the PM values.
• What: A method for understanding and optimizing transceiver power efficiency using the transceivers' internal telemetry. (from title only)
• How: Presumably reads internal metrics (per-lane power, DSP/CDR state, temperature) from pluggable optics and tunes operating points for power savings — plausible given the title, but unconfirmed.
• Where applicable: Potentially broadly applicable since it works on standard pluggables; the savings and the specific metrics exposed depend on the transceiver vendors/generations tested, so note those constraints.
