What is PD CLC/TR 50174-99-1- Cabling installation -Remote powering about?
PD CLC/TR 50174-99-1defines requirements and recommendations concerning limits for the application and operation of remote powering using cabling comprising balanced cabling components of Category 5 and above as defined in EN 50173-1.
PD CLC/TR 50174-99-1 also describes:
- A set of specific implementations which are the basis of a mathematical model for the temperature increases in bundles of cables under remote powering conditions
- A matching testing protocol used to provide data for the mathematical model
Note 1: The testing protocol was established in order to enable comparison of data from different sources in order to support the development of the mathematical model and to develop appropriate planning and installation rules as suggested by different installation conditions. It is not the role of CLC/TC 215 to develop test methods for balanced or other, cables and the protocol defined in Annex B is not as such a test method.
- The mathematical model that is employed as the basis for the resulting requirements and recommendations.
Note 2: Safety (electrical safety and protection, optical power, fire, etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of PD CLC/TR 50174-99-1 and are covered by standards and regulations. However, the information given in this Technical Report may be of assistance in meeting these standards and regulations.
Who is PD CLC/TR 50174-99-1 - Cabling installation -Remote powering for?
PD CLC/TR 50174-99-1on Cabling installation -Remote powering is useful for:
- Cabling installation teams
- Information technology industry
- Remote powering operators
- Electronics and Telecommunications industry
Why should you use PD CLC/TR 50174-99-1 - Cabling installation -Remote powering?
EN 50174 series specify the specification, planning and practices applicable to installation of telecommunications cabling.
Balanced cabling is increasingly used to provide power as well as telecommunication services to a wide range of terminal equipment. PD CLC/TR 50174-99-1 examines the effects of remote powering (i.e. thermal heating) on installed cabling.
PD CLC/TR 50174-99-1 demonstrates that the thermal impact of remote powering is proportional to the number of cables in a bundle (and/or the number of bundles installed in a close proximity to others) and the length over which that installation condition is maintained.
