scope:

This part of IEC 62807 is a family specification for FTTA (Fibre-To-The-Antenna) outdoor hybrid communication cables. It specifies the design and construction, rated values and characteristics, requirements and test methods, packaging and quality assurance, etc. The FTTA hybrid communication cables are typically but not only installed between the Base Band Unit (BBU) and Remote Radio Unit (RRU; or often called RRH - Remote Radio Head or AAU - Active Antenna Unit), and other scenario that supply electric current to optical communications equipment. The FTTA hybrid communication cables contain optical fibre elements and current carrying elements under a common outer sheath or other constructions unifying the elements. The current carrying elements shall be used only to supply power to the equipment within the communication network. The current carrying element shall not be used for electricity distribution or transmission, nor for power supply to domestic appliances. This part of IEC 62807 is to be used in conjunction with IEC 62807-3. The relationship between each of the MICE classifications in ISO/IEC 11801-1, the requirements and test methods of hybrid cables being proposed in a specific application, should be fully considered and aligned (see Annex A).
