With the development of car electronics, an increasing number of ECUs have been introduced to enginecontrols, brake controls (ABS), and navigation systems, etc. For further development of data communication units such as navigation systems as well as integration of car control systems, large capacity of data must be transmitted or received among ECUs in real-time processing. Optical communication, featuring niose resistance and high-speed processing, can meet the these requirements.
Naturally, there is a need for the development of optical couplens, which are essential for the construction of optical fiber networks.
For this reason, we developed optical star couplers to be basically connected with plastic fibers. This couplers will represent high performance at reasonable cost.
