At present, with the continuous development of domestic communication industry, optical fiber communication has entered the practical stage, and the scope of application is becoming wider and wider. my country now uses imported connectors for optical fiber connectors used in optical communication systems, or uses imported ceramic sleeves and peripheral metal parts and other so-called "parts" to be assembled in China, or according to imported foreign technology Produced with key equipment, mainly FC-type optical fiber connectors. In view of this situation, the author recommends the following.
(1) Standardization issues
There are many models and standards of optical fiber connector products in the world. If there is no restriction when introducing and using, it will inevitably cause confusion and bring inconvenience to maintenance and management. According to reports, the United States, Japan, Germany, France and other countries have established national standards in this regard and are recognized by the IEC; my country also has similar regulations in this regard. It is recommended that such regulations be published in the form of national standards as a content in technical documents such as technical specifications or network access requirements.
(2) Compatibility issues
Since communication is a system project, it is recommended that users consider the compatibility of optical fiber connectors used in optical transmission equipment, optical accessory equipment, and optical test instruments when ordering. On the basis of not affecting the performance of the system, the type of the optical fiber connector of the ordered instrument equipment should be consistent with that of the existing equipment. If it cannot be satisfied, you should consider possible problems during use, and order or prepare corresponding adapter flanges or adapter cables.
(3) Production and use issues
As far as production is concerned, it is recommended that the state guide relevant optical fiber connector manufacturers to develop based on a core component (such as Φ2.5mm pins and corresponding sleeves) in accordance with relevant regulations and combined with domestic existing and usage conditions. Develop products that meet national conditions and meet needs.
In terms of use, it is recommended that users choose the appropriate optical fiber connector according to their actual situation. On the premise of meeting the system requirements, fully consider the relationship between performance, price and development, and strive to reduce costs and expand the scope of use. In the future optical fiber user networks and high-speed local area networks, issues such as price and hardware upgrades may become more prominent, and users need to comprehensively consider performance, price, and development.
