Fiber Connector and its application, performance and requirements of the terminal
, Straight-through fiber optic connector (ST), fixed fiber optic connector (FC) and LC fiber optic connector and its application, performance, and terminal requirements. And A / V industry, widely used in the different BNC connectors, fiber optic connector with fiber optic technology continues to mature and progressive development. Copper Connector to 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 large effect. Let us look at the physical fiber optic connections in some of the problems arising from optical fiber transmission equipment itself may direct connection, but in some cases, most or almost all of the optical fiber connection options are man-made personally. Fiber optic cable in the signal transmission process of the signal is lost mainly by the amount of fiber optic cable used in the quality and type of decisions, each connector will have some signal loss. According to the user selected the type of fiber connector, connectors together with the amount of signal loss over fiber optic cable itself may generate the amount of signal loss.
Signal loss calculation The same with the power supply, optical power usually use dB,-3dB to measure. In the copper circuit, whether analog or digital signals, the connector is basically a loss of signal is "zero", meaning that the overall cable loss of volume compared to the signal generated due to contact resistance caused by the connector ohmic loss is usually negligible. Most of the optical fiber installed in the system, the situation is opposite. In AV applications, smaller than 1000 feet of fiber optic cable, signal loss will be less than the basic 3dB. In the case of a few kilometers distance transmission, multi-mode fiber dispersion becomes very important, so the best low signal loss of the single-mode fiber. However, whether close or remote transmission transmission, access to transmission signals each connector interfaces will have a lot of signal loss, usually the largest part of the signal loss occurred in the output side, installing a key to a good fiber optic connector is to try to connect to each other the interface between the fiber to minimize signal loss and maintain a certain signal loss within the estimated range for the system to provide long-term operation stability. Connector interface, the signal loss is measured with a dB. Since the end of fiber connections are not properly interrupt a light path will lead to a certain amount of signal loss, such as fiber surface is poor, non-parallel side connection and so on also make signal loss rate is much larger than expected amount of signal loss.
Speed laser optical fiber transmission of the development of the design of the terminal end has brought new problems. In the high transmission rate, reflecting the situation becomes very serious face, the need for angle grinding or ball milling, and other special treatment to reduce the loss rate. Signal loss from a more precise estimate in terms of extent, the normal port signal loss range of approximately between 0.1dB to 1.5dB maximum. Think about the signal from the source out through the distribution of machines, routers, workstations, the number of connections required contacts, contacts the more signal loss estimate increases the faster, but we have some unexpected circumstances into account range.
Table To maintain the normal operation of the system
In optical system design, the system to function, it reached very good results, in the system design, we need to consider the system may occur some unexpected problems, and let the system to the normal operation of the effect. In the system design, we have to consider the worst system possible, and to plan accordingly and look forward to a better operation of the effect. Fiber Connector designer must incorporate this idea to heart. In system design, security, stability, system connection requires smooth fiber ends, Founder. Connection between the client and the client must be precise, even to achieve micron precision, millionths of a meter. Commonly used multimode fiber from 50-62.5 microns in diameter, while the single-mode fiber is only 8-9 microns in diameter. To this diameter size and the diameter of a human hair (17-180 microns) compared to see any trace of the 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 components are usually mounted on a set of garden, 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 ri.
The connection, we should also be fiber optic connector wedge tight, in the present all the fiber optic connector design, through the "rings" to carry out, and ensure that connectors with accurate at the time. Viscose fiber terminals or by crimping the ferrule inside the confining, as a permanent component. After inserting a built-in optical fiber, put ring-side grinding is smooth, fiber-optic connections for the connector to provide smooth interfaces. Rings are usually relatively rigid material such as ceramics, of course, can also be stainless steel, plastic, or tungsten carbide material, SC, ST and FC Universal 2.5 mm ferrule diameter, LC common ferrule diameter to 1.25 mm. As the functional properties of rings can be produced in accordance with the requirements of precision, will become the first major fiber optic connector to determine properties. Among the many connections ferrule, the spring-loaded containers to connect fiber optic and LED ring guarantees or coaxial alignment between the laser source.
As technology development and application of expansion, the rapid development of fiber optic connectors. Now on the market use fiber optic connectors are about 12 species and even more, and each is to meet the specific needs emerge, of course, there are certain technical limitations. Now the market trend is mainly towards the moderate price, compact connector model development to support new transmission distribution system required greater transmission density. As user expectations, as the continuous development of the telecommunications industry also contributed to the large area fiber optic applications, largely due to various types of communications and entertainment services on fiber-optic connections due to the rapid growth in demand.
My first time using optical fiber system, with the AT & T launched in 80 ST connectors. ST multi-mode manipulation to LANs and CCTV systems?? ST seems to be a miniature BNC connector, the optical fiber, it is a simple blade-type switch to lock the connector, because not subject to any conservation treatment, easily damaged, so to deal with ST connector pay special attention to rings. ST connector is still present in a wide range of industry applications, but also gradually reduce its application.
FC connector is the ST connector sister product. FC said fixed
