Abstract
A Pulse Amplitude Modulated (PAM) optical device utilizing multiple wavelengths, features a communications interface having enhanced diagnostics capability. New registers are created to house additional diagnostic information, such as error rates. The diagnostic information may be stored in raw form, or as processed on-chip utilizing local resources.
Claims20
A method comprising:
- collecting data in a debugging memory of an optical transceiver of a module;
- communicating the data from the debugging memory to an engine of a master logic system;
- the engine of the master logic system processing the data to produce parametric information relevant for diagnostic purposes;
- and
- housing the parametric information in a new register of the master logic system.
