Optical communication system simulation
Optical communication systems using optical fibers as transmission media have excellent EMC characteristics. We are constructing a simulator that estimates communication performance in consideration of fiber routing (length, connector axis deviation, bending). Various DSP (Digital Signal Processing) such as multi-level coding and error correction technology can be applied. We also design customized passive components and optical systems.
Optical transmission system evaluation and standard conformance test
Standards such as 1000BASE-RH for Automotive Optical Ethernet define test points (TP) for the electrical and optical domains. ISO21111-3, -5 describes conformance test items and interconnectivity test items and their methods. ISO21111-4 specifies the test method for optical components with reference to IEC standards. This laboratory conducts these tests and proposes new test methods that are required.
