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
An optical communication module comprising:
- an optical transmitter element and an optical receiver element configured to handle communication of optical data and electronic data including digital signal processing (DSP);
- and
- a master logic control comprising a first register storing a first DSP parameter captured by a debugging memory, the master logic control configured to,
- receive from the optical transmitter element or the optical receiver element, additional raw parametric information relating to the optical data or the electronic data,
- cause an engine to process first DSP parameter with the additional raw parametric information to create second diagnostic information, and
- store the second diagnostic information in a new register.
