Fiber Optic Connector Application and its Terminal Consider Analysis

Fiber optic connector continues to develop

Fiber optic connector continues to develop with fiber optic technology gradual maturity. Copper connectors generally will not have great loss on the AV system signal, but the optical connection is different, which will play a very large effect on every interface in transmission system. Fiber optic transmission equipment may direct connections, but in some cases, most or almost all of the fiber-optic transmission connectivity options are artificially personally. The amount of signal loss by the optical fiber cable in the signal transmission process is decided primarily by the quality and type of the used optical fiber cable, each connecting terminal will produce a certain signal loss. According to different types of fiber optics connector selected by the user, the total amount of connecting terminal signal loss may exceed the amount of fiber optic cable signal loss.

Notes for the fiber optic system design

In the fiber optic system design, we achieve very good results if the system is capable of normal operation. In the system design, we need to consider some unexpected problems that may appear, and make the system to achieve the normal operation effect. The fiber optics manufacturer should keep this idea in heart. In system design, secure and stable system connection requires the fiber terminal to be smooth and square. The fiber optic connection has very stringent requirements for precision, so the connector must be very clean. Fiber optic connectors and accessories are usually mounted in a case, a finger print or external dust may seriously affect the performance of the connector, and even lead to transmission failure. Therefore, the connector should be stored in clean protective sleeve when it is not connected.

The primary determining characteristic of optical fiber connector

We should also wedge tightly the fiber optic connector at connection, which is carried out by "ferrule" among all optical fiber connector design to ensure the connector to be accurate when matching. The optical fiber terminal is inside the ferrule by adhesive or crimping tight hoop, which has become a permanent element. Ground the ferrule terminal smooth after inserting a built-in optical fiber, providing smooth connection interface for optical fiber splicer. Because the functional characteristics of the ferrule can be produced in accordance with the precision requirements, which becomes the primary determining characteristic of optical fiber connector. In connection ferrule, the spring container ferrule guarantees coaxial alignment between the fiber optic and LED or laser source.

Fiber optic connectors are rapid developing

With the technology development and expansion of application, fiber optic connectors are rapid developing. There are probably 12 or more fiber optic connectors used in the market, each of which is born to meet the specific needs, of course, there are also some technical limitations. Market trend develops toward compact connector mode development with a moderate price, which can support greater transmission density required by the new transmission distribution system. As users expect that the continuous development of the telecommunications industry also contributed to the large-scale application of the optical fiber, which is resulted by rapid growth in the demand of variety types of communications and entertainment services for the fiber-optic connection in large part.
