(一)简介光纤光电耦合器是专门为短距离光导纤维通信系统而设计制作的光电转换有源连接装置,是传光型或光强调制型光纤传感技术的关键部件。西欧通称之为Optical Fiber Link,日本则称之为光纤有源连接器。光纤传感技术或光纤通信系统中,使用光纤光电耦合器时,则不必考虑光纤与光电器件的光学性能和光纤耦合、接续等技术问题,大大简化了系统的设计及施工程序。上海电缆研究所研制的 ELOFEL 型光纤光电耦合器采用了独特的耦合技术,将红外发光二极管和光检测管分别封装于光导纤维两端的标准型三芯电插塞
(A) Introduction Fiber Optocoupler is a photoelectric conversion active connection device specially designed for short-distance optical fiber communication system. It is a key component of optical transmission technology or optical fiber modulation technology. Western Europe known as Optical Fiber Link, Japan called the fiber optic active connector. Optical fiber sensing technology or optical fiber communication system, the use of optical fiber optocouplers, you do not have to consider the optical fiber and optoelectronic devices and optical fiber coupling, connecting and other technical issues, greatly simplifying the system design and construction procedures. The ELOFEL optical fiber coupler developed by Shanghai Electric Cable Research Institute uses a unique coupling technology, and the infrared light-emitting diode and the light-detecting tube are respectively packaged on the standard three-core electric plug
