Transmitter Distortion Figure of Merit (TDFOM)

Keysight Technologies

Keysight and KD jointly developed a Transmitter Distortion Figure of Merit (TDFOM) measurement and signal analysis metric validating PMD transmitter conformance based on IEEE 802.3cz and Open Alliance. As specified in IEEE 802.3cz, TDFOM uses a reference receiver that models typical IC implementation, ensuring transmitter interoperability for accurate optical compliance testing.

The companies have jointly developed a Transmitter Distortion Figure of Merit (TDFOM) measurement and signal analysis metric validating PMD transmitter conformance based on the IEEE 802.3cz and Open Alliance.

The newly developed TDFOM measurement and signal analysis metric represents a significant advancement in evaluating multigigabit optical signal quality in glass optical fiber transmission. As specified in IEEE 802.3cz, TDFOM measurements utilize a reference receiver that models typical integrated circuit (IC) implementation, ensuring transmitter interoperability through signal integrity validation. This metric is essential for calibrating reference transmitters and enabling accurate compliance testing of optical receivers.
