517001-5

517001-5 is a standard for fibre-optic based transmission systems, used in the telecommunications industry. The standard specifies the technical requirements and operating principles for using various types of optical components, such as cables, optical amplifiers, receivers, etc., to create optical networks for transmission of data signals. This technology is becoming increasingly important and widely used, as the demand for higher transmission capacity increases.

The 517001-5 standard is divided into four main sections, each of which covers a particular aspect of the technology. The first section defines the general requirements for optical components and transmission systems. This includes the requirements for signal attenuation, dispersion, and so on. The second section covers the network architecture and design factors. These include topological considerations, network capacity, traffic management, etc. The third section focuses on the installation and testing of the transmission systems. This includes the installation of accessories, the connection of the various components, the assessment of performance, and the overall maintenance of the system. Finally, the fourth section outlines the specifications for certain types of cables. It states the types of cable, the lengths available, the type of connectors and other specifics.

Overall, the 517001-5 standard covers the installation and operating principles of fibre-optic based transmission systems. It outlines the requirements for various types of optical components, as well as the specifications for the cables used. The standard also provides guidance on network architecture design and installation, as well as the assessment of performance, maintenance, and other aspects. As such, it is an important tool used in the telecommunications industry for the creation of reliable optical networks.
