Application of fiber optic connectors and terminals

Fiber optic connectors and A/V industry BNC connector commonly used by different, with fiber optic technology continues to mature and get progressive development. Effect of copper connector signal loss of AV systems are generally not large, but the optical connection is different, its transmission system in each interface will play a very big influence. Let's look at the physical fiber optic connection problems arising from optical fiber transmission equipment itself may direct connection, but in some cases, most or almost all connectivity options are all man-made fiber transmission personally. Semaphore fiber optic cable in the signal transmission process of the loss is mainly determined by the quality and type of use of fiber optic cables, each connecting terminal will have some signal loss. Depending on the type of fiber optic connector selected by the user, the connection end signal is lost a combined total may exceed the amount of signal loss of the fiber optic cable itself.

Maintain a normal operation

In the optical fiber system design, system to normal operation, it reached very good results, in the system design, we need to consider the system may occur some unexpected problems, and let the system has reached normal operating results. In the system design, we have to consider the worst system possible situation and plan accordingly, expecting better operating results. Fiber Optic Connector designer must keep in mind to this idea. In system design, security, stability, system connection requires smooth fiber ends, Founder. The connection between the client and the client must be accurate and correct, or even to achieve micron precision, millionths of a meter. Commonly used diameter multimode fiber from 50-62.5 microns and single-mode fiber is only 8-9 microns in diameter. This compared to the diameter of a human hair in diameter (17-180 microns), showing no trace of error can bring in catastrophic losses.

Precision optical fiber connection to the equipment requirements are very strict, so connector must be very clean. Fiber optic connectors and accessories are usually mounted on a set of house, a finger print or external dust might seriously affect connector performance, even lead to transmission failure, therefore, when the connector is not connected, it should be kept in clean protective cover in.

In connection, we should also be fiber optic connector wedge tight, in the present all the fiber optic connector design, through the "collar" to ensure accurate at the time with the connector. Viscose fiber terminals or by crimping the ferrule inside the confining, as a permanent member. After inserting a built-in optical fiber, put the smooth ferrule end mill for fiber optic connectors provide a smooth interface. Rings are usually made of relatively hard material such as ceramics, of course, it may be stainless steel, plastic or tungsten carbide material, SC, ST and FC common ferrule diameter 2.5 mm, LC universal ferrule diameter 1.25 mm. Since the feature rings can be produced in accordance with the requirements of precision, it will become the primary fiber optic connector to determine important characteristics. Among the many connections ferrule, the spring-loaded ferrule ensures the container is connected coaxially aligned between the optical fiber and LED or laser source.

With the expansion of technology development and application of fiber optic connectors are also developing rapidly. Fiber optic connectors used now on the market there are about 12 kinds and even more, each of which is to meet the specific needs and came into being, of course, there are some technical limitations. Now the market trend is mainly towards the moderate price, compact connector model development to support greater transmission density of new transmission distribution system requirements. As user expectations, as the continuous development of the telecommunications industry also contributed to the large-scale application of optical fibers is due to various types of communication and entertainment services on fiber-optic connections due to the rapid growth in demand largely.

Consider terminal

Traditionally, fiber optic terminal is generally slower, the price is higher, the equipment requirements and technical requirements are high. When considering a single-mode fiber optic cable in the terminal, you should take into account several factors in this regard. In some cases, we can choose some already set in accordance with various fiber types good terminal cables.

Tailor-mount applications, we can select a specific terminal, however, adopted after splicing tools, you can reduce on-site terminal extension of the length of the single-mode fiber, reducing the use of the equipment and technology of the quantity demanded. After the multimode fiber optic cable, the new splicing method using a simple optical fiber cutting method, will be assembled into a pre-designed cable connector / cable. This method is very simple, but the fiber-to-fiber connectors butt joints usually uses a special optical gel, so that fiber optic terminal curdle.
