Title:
ホストに報告する前の光送受信機のデジタル診断情報の補正
Document Type and Number:
Japanese Patent JP4558791
Kind Code:
B2
Abstract:
An optical transceiver configured to perform calibration of digital diagnostics prior to providing the calibrated values to a host computing system (hereinafter referred to simply as a "host") that is communicatively coupled to the optical transceiver. The optical transceiver includes a sensor that measures an analog operational parameter signal such as temperature or supply voltage. Each analog signal is then converted to digital samples by analog to digital converter(s). A processor executes microcode that causes the optical transceiver to perform calibration on the various samples to compensate for predictable error introduced into the analog signal prior to or during the analog-to-digital conversion. The optical transceiver may then make the calibrated result accessible to the host.
