And based on the connector construction, LC connector also can be divided into LC duplex and simplex connector. There are single mode LC connector and multimode LC connector. As one popular SFF (small form factor) connector, LC fiber connector has a ferrule of 1.25mm, which make it perfect for high density cabling. Here are five common optical cable connectors.ĭeveloped by Lucent Technologies, the LC fiber optic connector has become the ubiquitous fiber connector for today’s optical telecom applications, especially for connections with SFP and SFP+ fiber transceivers. And these fiber connectors are widely used in the termination of optical fibers like fiber optic pigtails. However, no matter what the fiber connector types are, they have the same function and similar basic components-ferrule, connector body and coupling device. And the most commonly used fiber connector types includes LC, SC, MU, ST, FC, MTRJ, NID, E2000 and MTP/MPO connector. In the present fiber connector market, there are about 100 fiber optic cable connectors in total. Then how many fiber connector types do you know or use? What are the differences between single mode fiber connector and multimode fiber connector? Find details in the following parts. A number of fiber connector types have been evolved and withstood the test of time to become industry standards. Fiber optic cable connectors come in many configurations and usages, and simplify fiber optic cable installation and maintenance greatly. Knowing the fiber color codes is good for fiber core splicing, allocation, reservation, and backup.Fiber connectors, also called fiber optic cable connectors, are often used to link optical fibers where a connect or disconnect capability is needed. The colors of the cores are: blue, orange, green, brown, slate, and white. For example, a 24-core fiber optic cable has four bundle tubes, they are blue, orange, green, and brown tubes. The colors of the bundle tubes and cores are arranged in color order. The core is in a white tube.įor optical cables with more than 12 cores, the commonly used stranded optical cable is composed of multiple bundle tubes, lining tubes, and fiber cores. Generally, the central bundle tube type fiber optic cable has 4, 6, 8, 12 cores, etc. If the fiber optic cable is less than 12 cores, it can be installed with a bundle tube, then 12 colors of fiber cores can be placed in a bundle tube. Similar colors are not easy to distinguish for myopic friends. As for why there are 12 colors, it is because 12 typical colors are selected from many colors to help distinguish and identify. The order of the national standard cores is: blue, orange, green, brown, slate, white, red, black, yellow, violeta, rose and aqua. Generally, the full chromatographic identification is adopted. The color of the optical fiber and the sleeve in the optical cable is to facilitate us to remember the corresponding relationship between the cores and to prevent errors in the core connection. Today, the author specially drew a sequence diagram of all colors of optical fibers, which is convenient for everyone to remember, and is handy for future work as a reference. Splicers who work in optical fiber communication engineering often worry about memorizing the color sequence of optical fibers. Fiber Optic Tools Cleaner Test Equipments.
