Introducing RF connectors and fiber optic connectors

Connectors are very common in life, but some of them are not well known. In order to enhance people's understanding of connectors, this article will introduce connectors based on three aspects: ① RF connectors; ② how to use fiber optic quick connectors; ③ the difference between LCuniboot connectors and LC fiber optic connectors. 1. Naming method of RF coaxial connectors: There are two kinds of codes, namely name code and structure code, which are separated by a short horizontal line "-". Main name code The main name code of RF connector adopts the international general main name code, and there are detailed specifications for the naming of specific product structure forms. (1) Selection of RF connectors 1. The selected RF connectors meet the actual frequency range. 2. Compared with the bent RF connector, the straight-RF connector has better electrical performance and can be selected according to the actual use. 3.The selected RF connector has a small SWR. 4.The insertion loss of the selected RF connector is small. 5.The selected RF connector matches the impedance of the mating RF connector or cable. 6.The EMC of the threaded RF connector is superior to any bayonet type, push-pull RF connector. 7.If there is an IM requirement, consider the material and coating of the RF connector. 8. Universal RF connectors do not select high performance RF connectors when they meet the requirements. (2) Problems that should be paid attention to when choosing 1. Cost performance ratio. 2. Inventory and procurement cycle. 3. Testability, reliability, changeability, etc. 4.The connector operates at a high frequency for the signal. When customizing pin distribution, consider signal integrity and pay attention to signal and pin assignments. 5. The operating voltage and current of the connector, taking into account factors such as power supply decoupling and heat resistance. 6.Number of joints. In general, the principle of fewer connections and more contacts shall be followed. 7.Connection installation method and installation precautions. 8. Are there any precautions for the specific fastening method of the connector. For example, whether it is necessary to ensure that there are no excessively high devices within a certain range around the connectors, so as to avoid equipment interference. 9. Whether EMC issues need to be considered.

2. How to use the optical fiber quick connector In addition, people also use the optical fiber quick connector as a movable connector, which can connect the continuous optical channels formed by two optical fibers. This device can be reused many times, which is faster and more convenient to use. According to the structure, it can be divided into two types: mechanical connection and hot melt connection; mechanical connection can be divided into embedded type and direct embedded type. All kinds of optical fiber quick connector materials have low performance and stability, and their service life and cost are different. How to use the specific optical fiber quick connector? The optical cable quick connector is mainly composed of a body, a shell and a tail cover. It should be noted here that after the items on the packaging bag are removed, the packaging bag should not be thrown away for later use. 1. Thread the rubber-covered optical cable from the tail cap, and peel off the surface skin with scissors for about 5 to 6 cm. Then cut off the outer skin, taking care to keep the outer skin on both sides flush. Be careful when stripping so as not to damage the internal fiber optic cable. 2. Put the optical cable into the fixture, and make the outer edge flush with the scribe line in the fixture, then close the cover plate, and then use Miller pliers to cling to the edge of the fixture, cut off the exposed optical fiber from the exposed coating, and then clean the exposed white optical fiber with alcohol. 3. Cut the optical fiber with a clamp. After cutting, take the optical cable out of the clamp and compare it with the figure on the product packaging bag. And then that optical fib is inserted aft being aligned with the main hole groove, the bottom of the main mold is pressed, the optical fib can be clearly observed to be bent at the moment, the white crimping cover on the main body is pressed to the bottom, and then the tail cap is screwed on the main body and buckled. 3. Difference between LCuniboot connector and LC optical fiber connector 1. Compact design meets the requirements of high-density applications. LCUniboot uses a dual-fiber single-tube, integrated tail sleeve, which eliminates the need for dual-chain cables, and it is more compact than ordinary LC duplex fiber patch cables, saving space and reducing the total wiring by 50%. At the same time, it is conducive to the heat dissipation of the wiring system, more rational use, in order to achieve greater energy efficiency. 2. Change the polarity, easy to operate. What is the polarity of the optical fiber? Optical polarity refers to the direction in which an optical signal is transmitted in an optical fiber. In general, there are a transmitting signal (Tx) and a receiving signal (Rx). LCUniboot optical fiber connector innovatively sets the two plugs of the optical fiber connector to be adjustable to each other, helping users to simply reverse the polarity of the optical fiber, and easily open the ferrule and switch the polarity without any tools. 3. Pull rod design. The connecting piece can be unlocked by one hand in a high-density environment, which is simple and convenient. The push-pull rod can be easily inserted or pulled out, even in high-density environments. The half-pack tail end structure can also prevent the cable from winding. The innovative LCuniboot fiber optic connector, with its unique structure and compact design, performs better than traditional LC duplex connectors in high-density cabling environments, making it ideal for data centers and FTTX.
