1 Scope
This European Standard defines outdoor multi-pair/quad cables for use in high bit rate telecommunication networks with their relative definitions and requirements.
It covers radially water blocked cables, with an overall screen, with performances up to 60 MHz, to be used in outdoor networks intended to connect the broadband outside plant to the individual customer premises with a maximum recommended length of connection of 1 km.
The electrical, environmental, mechanical and transmission performance characteristics of the cables, related to their reference test methods, are detailed.

4 General information
4.1 General cable description
These cables are designee for outdoor high bit rate telecommunication networks. They are waterblocked cables with an overall screen.
High bit rate applications targeted in this specification involve frequencies up to 60 MHz. To restrict emission and to ensure satisfactory electromagnetic immunity, these cables include an overall screen.
These cables contain from one pair up to 200 pairs (ffs) that can be either in pairs or quads.
4.2 Environment and product safety requirement.
Safety local and regional regulation (e.g. relevant European directives) is assumed to be met by these cables.
4.3 Testing
For all test procedures described in this subclause, the test conditions shall be the standard atmospheric conditions (23 ± 5)°C and 20 % • 70 % Relative Humidity, unless otherwise stated. All measured and computed values are to be rounded to the number of decimal places given in the corresponding requirement or objective.
The parameters specified in this standard may be affected by measurement uncertainty arising either from measurement errors or calibration errors due to a lack of suitable standards. Acceptance criteria shall be interpreted with respect to this consideration.
5 Requirements for conductor
5.1 Construction and dimensions
The conductor shall consist of annealed copper, uniform in quality and free from defects. The properties of the copper shall be in accordance with IEC 60028.
The conductor shall be solic, circular in section. Normally the conductor should be drawn in one piece.
Joints m the conductor are permitted, provided that the tensile strength of a joint is not less than 85 % of the un-jointed solid conductor.
The diameter of the conductor shall be between 0,4 mm to 0.8 mm.
5.2 Mechanical requirements
The conductor elongation al break shall be tested according to EN 50289-3-2 and shall be minimum
10 % for 0.4 mm wires and better than 15 % for wires with diameters superior to 0.4 mm.
