China once again dominates the International Standard of ITU-T Optical Cable facilities

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 the CRU report data, in 2018, the global FTTX construction fiber consumption of 180 million core kilometers, the total length of about 4,500 circles 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 of different countries are quite different, and the cable and cable facilities are not standardized. Even in different countries, even the product names are varied.

Light splitter boxes, transfer boxes and other boxes, like the traffic road "overpass", is a 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” was jointly reviewed and approved by Fiberhome Communications. 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 properties and environmental performance of fiber management systems, fiber optic cable accessories, spectroscopic/fusion cabinets, etc. The published ITU-T L.206 "passive optical node technical requirements: outdoor optical junction box" and other international standards together constitute 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 standards in June 2017. The first draft of the draft, which lasted for 3 years, after several discussions and comments, finally completed the development of the ITU-T L.208 standard.

At this ITU-T SG15 plenary session, Fiberhome Communications experts also received an editorial seat for another international standard, ITU-T L.151, "Installation of Optical Fiber Composite Overhead Ground Cable (OPGW), which means that the campfire will take the lead. The revision of this international standard. ITU-T standard L.151 was published in 1998, which stipulates the technical requirements for the installation of optical fiber composite overhead ground cable (OPGW). Due to the early development of this standard, with the development of technology, the original part is not perfect. The details of some technical requirements are not provided. It is impossible to effectively guide the installation during construction. For example, the requirements for the construction line force value of the cable are recommended. “The appropriate tension” is not given. value. Based on the technical accumulation and installation and construction experience of its own OPGW, Bonfire proposed a number of revision proposals, such as pre-installation inspection, construction line tension, acceptance criteria and content requirements, which were adopted by the meeting and agreed to initiate the revision project.

Bonfire attaches great importance to the development of international standards, and has participated in the work of all influential international and domestic standards organizations. More than a dozen experts have served as chairpersons, speakers and editors in international standardization organizations such as ITU-T, IEEE, and OIF. A number of important positions, including people, have taken the lead or participated in the formulation of more than 30 international standards, more than 100 national standards, and more than 300 industry standards.
