Technique for Testing Optical Fibers by Using Electronic Microscopy

Optical fibers have several advantages over traditional communication lines, such as: support higher bandwidth, less susceptibility to interference, stronger data security, they are much thinner and lighter, etc. The paper proposes a technique that characterizes, describes and defines a guided environment imported into the European Union (EU), which complies with the recommendations of the International Telecommunication Union (ITU-T) G.652.D and G.657.A2. Using this technique, a product (optical fiber) can be framed either under the European Union Integrated Tariff (TARIC) code 85447000 00, for which customs duties have a level, or under the TARIC commodity code 90011090 90, for which the value of custom duties would be calculated on the basis of a certain percent. In comparison to other techniques used in practice, the technique proposed by us requires, in addition, a multitude of new tests, which can fit the optical fiber in one of the fields of applicability, respectively, telecommunications, IT communications, various industrial or medical applications for the purpose of classification under a TARIC commodity code.
