Jig and calibration method

摘要

A jig for calibrating a light transceiver module includes a disposition region for the light transceiver module on which the light transceiver module is suitably disposed and an arc structure, which takes the position of the disposition region for the light transceiver module as a circle center thereof and includes reflective regions, light-absorbing regions and a feature region. The reflective regions and light-absorbing regions are alternately arranged, and the feature region is a region for reflection or for absorbing light. When the feature region is the region for reflection, the width of the region for reflection is different from the width of each the reflective region, and when the feature region is the region for absorbing light, the width of the region for absorbing light is different from width of each of the light-absorbing regions. A calibration method is also provided.

主权项

1. A jig, configured to calibrate a light transceiver module and comprising:
a disposition region for the light transceiver module, wherein the light transceiver module is suitable to be disposed on the disposition region for the light transceiver module; and an arc structure, taking a position of the disposition region for the light transceiver module as a circle center thereof and comprising: a plurality of reflective regions; a plurality of light-absorbing regions, wherein the reflective regions and the light-absorbing regions are alternately arranged; and a feature region, being a region for reflection or a region for absorbing light, wherein when the feature region is the region for reflection, a width of the region for reflection is different from a width of each of the reflective regions, and when the feature region is the region for absorbing light, a width of the region for absorbing light is different from a width of each of the light-absorbing regions.
