Description

Fiber optic adapter

The present invention relates to a fiber optic adapter, and more particularly to a fiber optic adapter capable of transmitting electrical signals.

Optical fiber is a kind of light-conducting tool that allows light to be transmitted in the fiber made of glass or plastic by the principle of total reflection. It has the following advantages: 1. Low loss, high frequency width; 2. Light weight, small size, small bending radius ; 3. Non-conductive, non-radiative, non-inductive.

Low loss, high frequency width is characterized by the fact that the transmission loss of light in the optical fiber is much lower than that of the electric transmission in the wire, and the frequency band is wider, so that the data transmission can be carried out in a large amount and quickly; the weight is light, the size is small, and the bending radius is small. The small features make the fiber have considerable convenience in space utilization; the characteristics of non-conducting, non-radiating, and non-inductive are due to the fact that the fiber is made of a material of a non-metal medium, so it has an excellent anti-electromagnetic signal. The ability to interfere, so it can avoid the radiation interference caused by the use of metal as a transmission medium, ground loop and induction related problems.
