Abstract
Embodiments of the present disclosure provide techniques and an apparatus for partitioning calibration data into line card and pluggable properties and processing the partitioned data using a processor of the line card. For example, calibration information corresponding to components in the pluggable module may be stored on the pluggable module and transferred from the pluggable optical module to the processor on the line card. The processor may combine the calibration information received from the optical module with calibration information corresponding to properties on the line card to obtain system calibration information. The system calibration information may be used to configure one or more components used to process electric signals sent to or received from the optical module.
Claims20
An apparatus, comprising:
- an electrical connector configured to connect an optical module to the apparatus;
- and
- at least one processor configured to:
- receive, from the optical module via the electrical connector, first calibration information corresponding to a first plurality of elements of a communication channel between the apparatus and an optical input and output of the optical module;
- combine the first calibration information with second calibration information to obtain system calibration information, the second calibration information corresponding to a second plurality of elements of the communication channel;
- calibrate one or more components configured to process electrical signals based on the system calibration information.
A pluggable optical module, comprising:
- at least one storage device comprising calibration information corresponding to a plurality of elements of a communication channel between an apparatus and an optical input and output of the optical module, wherein the optical module is configured to plug into a port of the apparatus;
- and
- a controller configured to:
- determine that the optical module has been connected to the apparatus;
- and
- transfer the calibration information from the optical module to the apparatus;
- and
- a transmitter configured to:
- receive an electrical signal from the apparatus, wherein one or more components configured to generate the electrical signal are calibrated based on the calibration information;
- and
- generate an optical signal based on the electrical signal from the apparatus.
A method, comprising:
- receiving first calibration information corresponding to a first plurality of elements of a communication channel between an apparatus and an optical input and output of an optical module, wherein the optical module is pluggable into the apparatus;
- combining the first calibration information with second calibration information to obtain system calibration information, the second calibration information corresponding to a second plurality of elements of the communication channel;
- and
- calibrating one or more components configured to process an electrical signal, based on the system calibration information.
