The New Development Policy Of Dual-core Optical Cable Inspection And Measurement
In terms of the current production of plastic optical fibers, Japan is the world's largest producer of plastic optical fibers, but it is Europe that promotes the development of new application areas for plastic optical fibers and establishes optical fiber inspection standards. The second half of 2001 was an important stage in the development of the European plastic optical fiber industry. During this period, a new development policy for European plastic optical fiber inspection and measurement was established. The world's first dedicated plastic optical fiber application center (POFAC) was completed in Nuremberg, Germany. Germany has successfully developed a multimedia bus system MOST (24Mbit/s) using plastic optical fibers, and several car manufacturers have introduced this system into their products. The German BMW company (BMW) has set a record for the use of 100m plastic optical fibers in its new 7 series of products. The European 2001 Plastic Optical Fiber Academic Exchange Conference and the European Optical Fiber Communication Conference were held simultaneously in Amsterdam, the Netherlands. The German automobile industry not only promoted the application of plastic optical fibers, but also promoted the establishment of inspection and measurement standards for plastic optical fibers.
Japan has also established plastic optical fiber standards, but these standards are invalid for the European Community. The Japanese Industrial Standard only provides a standard for one type of plastic optical fiber with a numerical aperture of 0.5 and only one wavelength at 650 nm. The standard does not mention the different excitation light conditions in the plastic optical fiber, nor does it stipulate that a balanced mode distribution must be formed in the plastic optical fiber.
The previously established glass optical fiber inspection method is not suitable for inspecting plastic optical fiber because of Rayleigh scattering. Now there is only an instrument for inspecting plastic optical fiber sold by the newly established Swiss company Luciol Instruments.
