Contract testsAutomotive communication standard conformance tests
Automotive optical transmission system evaluation and
standard conformance tests
Standards such as automotive optical Ethernet 1000BASE-RH determine the test point (TP) of the electrical domain and the optical domain. In additon, ISO21111-3,-5 describe conformance test items and interconnection test items as well as the methods. ISO21111-4 specifies test methods for optical components with reference to IEC standards. In addition to conducting these tests, our laboratory proposes new test methods (ex IEEE P802.3cz and IEEE P802.3dh) if necessary.
