Communication connectors should go this way in the future

Communication connectors are interconnecting devices for network transmission media, and the performance of the connectors used may affect the entire communication system. At present, there are many models and standards of communication connector products, including fiber optic connectors and electrical connection devices. With the different application objects, frequency, power, application environment, various forms of communication connectors are required. When selecting communication connectors, it is necessary to select the applicable connector according to their actual situation:It is necessary to be familiar with and understand the performance of various types of connectors, consider the construction costs and hardware upgrades when the network is upgraded to a high-speed network, and put forward the interface requirements; and comprehensively consider the connector's performance, price and development. In the fiber optic communication link, in order to achieve different modules. As well as the need for flexible connections between equipment and systems, there must be a device that can be detachably (movably) connected between optical fibers, so that the optical path is transmitted in accordance with the desired channel, in order to achieve the predetermined or expected purposes and requirements. The device that can perform this function is called a fiber optic connector. A fiber optic connector is a device that precisely connects the two end faces of an optical fiber so that the light energy output from the transmitting fiber is coupled to the receiving fiber to the maximum extent possible, and so that its intervention in the optical link has the least impact on the system. To some extent, fiber optic connectors also affect the reliability and performance of the optical transmission system.

Electrical connectors in communications allow current to flow in the blocking portion of a circuit or in an isolated circuit, allowing the circuit to fulfill its intended function. Some connectors are made into common sockets and are widely recognized and used in the cable industry. The connection of a network often depends on the medium used, so connectors are often discussed in terms of different connection mediums, connection methods and applications, usually including multi-wire cable connectors, twisted pair cable connectors and coaxial cable connectors. Multi-wire cable connectors include DB connectors and DIX connectors and DIN connectors and so on. Twisted-pair connections include RJ45 and RJ11;; coaxial cable connectors include t-connectors, BNC connectors and termination resistors. Among them, the widely used RF coaxial connectors can be categorized into threaded connections, bayonet connections and direct push connections. Both fiber optic connectors and electrical connectors are constantly developing. The following is a summary of the development of these two types of communication connectors by Longhao Electronics. Influenced by the rapid growth of China's telecommunications industry, the RF connector market has seen unprecedented momentum. With the development of the telecommunication industry, from the initial voice application to the application of mobile Internet and mobile TV, the requirement of data transmission rate is getting higher and higher. In order to transmit higher speeds, optical fibers have begun to replace traditional copper cables, especially in RRH, which not only greatly improves long-distance high-capacity transmission rates, but also reduces the cost compared to copper cables. With the application of fiber optics in communication infrastructure, the demand for fiber optic connectors is gradually increasing. With the continuous development of wireless communication technology, "board-to-board" coaxial connectors are widely used in the interconnection of wireless system modules, such as communication base stations, RRH, repeater, GPS equipment and other similar applications. Initially, the circuit boards of RF modules were mainly connected by cable assemblies. However, with the miniaturization of the product, the connection between the components becomes more and more tight, the cable assembly can not meet the requirements. As a result, board-to-board connectors were created, evolving from limited to large tolerances. In the field of electronically interconnected components, metals are non-renewable raw materials, while synthetic materials are recyclable. In mass production, synthetics have a cost advantage over metals. Compared to metals, synthetics are considerably lighter. For equipment manufacturers, the reduced weight reduces transportation costs accordingly. In addition, synthetic materials are also very good in terms of corrosion resistance, more suitable for harsh outdoor environments than metal materials. The adoption of synthetic materials for communication connectors may become a trend. In the past two years, foreign companies have gradually moved their R&D bases to China, which will become the core market of the telecom industry. In addition, many international first-tier interconnect suppliers, such as Tyco and molex, are stepping into the construction of optical networks in China with their technical advantages. The competition in the domestic telecom connector market will be more intense in the future.
