Application area:
High-frequency twisted pair cable for structured cabling systems intended for horizontal and vertical outdoor installation along building walls, suspension on aerial communication lines, and spanning between poles or buildings. The cable operates in the frequency range up to 100 MHz (Category 5 and 5e according to GOST R 54429-2011) and ISO/IEC 11801. The cables are manufactured in climatic version UHL, placement categories 1 and 2 according to GOST 15150.

- Characteristic impedance Zc, Ohm: 100±15
Operating and installation conditions:
Cables may be operated at ambient temperatures from −60 °C to +60 °C. Cable installation is permitted at temperatures not lower than −20 °C.
The minimum permissible bending radius during installation and operation must be at least 8 maximum outer cable diameters.
Reliability requirements:
The minimum service life of the cables, provided that installation rules, operating conditions, storage and transportation requirements are followed by the consumer, shall be at least 25 years. The service life is calculated from the date of cable manufacture.
