　　Understanding of the cam and groove coupling is not much, except for some people who use it regularly . Therefore, this article is to introduce people to cam and groove coupling.

　　Cam and groove coupling feeders used in the microwave and radar technology . It usually has multiple ports , you can connect a lot of lines. It consists of two parts and the light emitting source composed . It is the light source and the light assembly in the same closed housing , isolated from each other with a transparent insulator. Light source as an input , the output of the optical receiver is a common light source is a light emitting diode , the light is a photodiode.

　　Cam and groove coupling works. At the input cam and groove coupling of the light source so that light emission on signal intensity of the light depends on the size of the excitation current , when the light is irradiated together with the package on the light , a photoelectric effect due to the photocurrent generated by the light receiving the output of lead , thus achieving an electro-optical power conversion. Under certain light emission current IF, yo very important relationship between the bias voltage VCE of photodiodes , and the output current IC. When IF = 0 , the light emitting diode does not emit light called dark current of the output current is generally small . When the IF> 0 , the effect under certain IF , IC, and VCE unconnected.
