China once again dominates the international standard for ITU-T cable installations


In recent years, the world's telecommunications infrastructure construction has developed at a high speed. One of the important contents is the construction of FTTX. According to CRU report data statistics, in 2018, the global FTTX construction fiber consumption of 180 million core kilometers, the total length of about 4,500 laps around the earth, reached a new peak, FTTX fiber optic cable accounted for 35% of all cable demand. All countries in the world have encountered major problems in the construction of FTTX: the national conditions vary greatly, and there are no uniform specifications for optical cable facilities. Even in different countries, even product names are varied.

Light splitter boxes, transfer boxes and other boxes, like the "overpass" of traffic roads, are the local hub of the FTTX cable network. The international standardization of this type of cabinet helps to ensure smooth and accurate fiber routing between equipment room, trunk cable, distribution cable and home optical cable, and greatly regulates equipment manufacturing and construction.
Recently, at the ITU-T SG15 plenary meeting held in Geneva, Switzerland, the international standard ITU-T L.208 "passive optical node technical requirements: optical fiber splitting box" jointly led by Fiberhome Communications was approved by the Plenary. This is the second time that China has once again led the international standard for ITU-T fiber optic cable facilities after the adoption of ITU-T L.206, which was jointly led by Campfire. China has issued an increasingly strong voice in the work of international standards.

The new standard ITU-T L.208 specifies the general technical requirements for indoor/outdoor optical fiber splitting boxes, including the mechanical and environmental performance of fiber management systems, fiber optic cable accessories, spectroscopic/fusion cabinets, etc. Together with international standards such as ITU-T L.206 "passive optical node technical requirements: outdoor optical junction box", it constitutes a complete passive optical node technical requirements standard system. The official release of this series of standards will effectively promote the standardization of optical network physical facilities related products and the unification of design languages, and promote the development of international trade in the communications industry. Since September 2016, the editorial team composed of experts from China Information and Communication Research Institute, Fiberhome Communications, China Unicom, and Commscope Connectivity has promoted the successful establishment of L.208 and formed a standard in June 2017. The first draft of the draft, which lasted for three years, after several discussions and comments, finally completed the development of the ITU-T L.208 standard.
