Embedded parametric monitoring of optoelectronic modules
First Claim
1. In an opto-electrical module for converting and coupling information-containing signals with an optical fiber, a method of storing operational information about the opto-electrical module for failure analysis comprising:
- maintaining a total elapsed time the module has been operating;
sensing parameter of interest values during operation of the module;
during operation of the module, using data compression to store the total elapsed time and the parameter of interest values in a compressed format in a finite nonvolatile memory; and
overriding default settings on the module and setting the total elapsed time to a non-zero value.

Abstract
An optoelectronic module for converting and coupling an information-containing electrical signal with an optical fiber including a housing having an electrical input for coupling with an external electrical cable or information system device and for transmitting and receiving information-containing electrical signals over such input, and a fiber optic connector adapted for coupling with an external optical fiber for transmitting and receiving an optical signal; an electro-optic subassembly coupled to the information containing electrical signal and converting it to and/or from a modulated optical signal corresponding to the electrical signal; and parametric storage means disposed in said housing for storing environmental and/or operational data associated with the module.
