Brief introduction of plastic optical fiber
Plastic optical fiber. By the end of 20 14, the optical fibers used in communication cables are basically time-sensitive fibers, which are composed of high-purity silica SiO2 _ 2 and appropriate dopants. In recent years, plastic optical fibers made of light-transmitting polymers have been gradually developed. Because the simple drawing process with mature polymer can be used, the cost is relatively low, and it is soft and firm, with large diameter (about 1mm) and low connection loss.
There are two main materials for making POF: one is polymethyl methacrylate (PMMA); The other is perfluoropolymer.
Plastic optical fiber connection
There are two ways to connect optical fibers: thermal welding and mechanical connection:
Thermal welding is the use of optical fiber welding machine. First, the coating is removed from both ends of the optical fiber to be spliced, then the surface of the optical fiber is cleaned with a cleaning solvent, and then the end face is cut. This step is more critical. The end cutting of optical fiber directly affects the welding quality. Then insert the optical fiber into the welding machine, and the automatic alignment process of the optical fiber axis can be observed through the display screen. After the fusion splicing is completed, joint attenuation will be displayed. According to the China building code, the fusion attenuation of discrete optical fibers should be less than 0.08dB.
Mechanical splicing (commonly known as cold splicing) adopts cold splicing. The operation is simple, the steps are the same as above, but no welding machine is needed. Generally used in the home end of optical cable. Its splicing principle mainly depends on the switching fluid in cold splicing, and the joint attenuation can be less than 0. 15dB.
Plastic optical fiber cutting
1. can smoothly cut bare optical fibers or cables with diameters of 0.75mm, 1.0mm, 1.3mm, 1.5mm and 2.2mm.
2. It can complete 1.5 * 3.0mm and 2.2 * 4.4mm twisted-pair parallel optical cables.
(1) fixed-length cutting (that is, cutting optical fibers and cables of any length);
(2) End face cutting (modifying the end face of optical fiber and optical cable);
(3) branch line.
3. The peeling (stripping) of the surface cortex of 1.0 * 1.5mm and 1.0 * 2.2mm single-strand optical cables can be completed. ..
Plastic optical fiber jumper
Plastic optical fiber jumper is the transmission of multimedia guidance system.
The M. O.S.T (Media Oriented Data System Transmission) standard was jointly formulated by 16 major European automobile manufacturers in 2000. The standard stipulates that plastic optical fiber is used as the transmission medium of data network in the car, which mainly supports the application of entertainment information in the car, so that the transmission speed of information in the car can reach 900 Mbit/s ... German BMW also announced that the most advanced new car BMW7 series listed in 2002 adopted the M.O.S.T (MediaorientedSystemStransport Transmission) standard.
O.S.T. (short for meter) plays a leading role in the field of short-distance data transmission and industrial automation, especially in improving automobile safety and information and entertainment functions. Shanghai Zhijin Optical Fiber Network Technology Co., Ltd. has been committed to the development and application of plastic optical fiber connection technology; With the application of plastic optical fiber in automobiles, a series of jumpers are introduced to ensure the high quality of plastic optical fiber jumpers with strict end polishing technology and strict optical fiber testing methods.
