Overview

EN 50288-10-2:2015 is a CLC/CENELEC sectional specification for screened multi‑element metallic cables characterized from 1 MHz up to 500 MHz, intended for work area, patch cord and data centre applications. It defines construction, electrical, mechanical, transmission and environmental performance requirements for cords used in horizontal and building backbone cabling and is to be read together with EN 50288-1 (generic specification) and the premises cabling standards in EN 50173.

Key topics and technical requirements

This standard covers both construction and test requirements for screened cables (pairs or quads). Key technical topics include:

• Frequency range: 1 MHz to 500 MHz - targets high‑performance screened twisted pair and quad cabling for data and control.
• Cable construction: Conductor (solid or 7‑strand annealed copper), insulation and sheath materials per EN 50290‑2 series; conductor diameter limits (solid ≥ 0.40 mm ≤ 0.80 mm; stranded 7 × 0.10–0.21 mm).
• Screening requirements: Core and element screening options (foil, braid); minimum braid coverage 60% (braid only) or 30% where foil+braid is used.
• Electrical parameters and test limits:
  • Conductor loop resistance D1 ≤ 28.0 Ω/100 m (D2 ≤ 34.0 Ω/100 m); conductor resistance unbalance ≤ 2% (pair ≤ 4%).
  • Dielectric strength (e.g., 1 kV DC or 0.7 kV AC for 1 min; higher short‑duration voltages also specified).
  • Capacitance unbalance to earth ≤ 1 200 pF/km.
  • High‑frequency transmission metrics including attenuation, NEXT, ACR‑F, PSNEXT, and velocity of propagation (specified formulas and tabulated limits across 1–500 MHz).
  • Skew (propagation delay difference) ≤ 45 ns/100 m at 100 MHz.
• Mechanical & environmental testing: Tensile, elongation, crush, impact, bending, abrasion and temperature cycling per referenced EN 50289 series test methods.
• Informative annexes: POE maximum voltage/current/temperature guidance and a blank detail specification template for manufacturers/specifiers.

Applications and users

This standard is aimed at:

• Cable manufacturers and designers producing screened work‑area cords, patch cords and data‑centre interconnects.
• Systems integrators, data centre operators and cabling specifiers selecting components compliant with EN 50173 reference implementations.
• Test laboratories and installers verifying attenuation, NEXT, ACR‑F, PSNEXT, and mechanical/environmental performance.
• Procurement teams requiring documented compliance for horizontal cabling, patch panels and cross‑connects in commercial and enterprise networks.

Related standards

• EN 50288‑1:2013 (Generic specification)
• EN 50173 series (Premises cabling)
• EN 50290‑2 series (Materials & construction rules)
• EN 50289 series (Test methods)
• IEC 60189‑2 / EN 60708 (Insulation and identification)

This specification helps ensure screened cabling used in modern communications and data centre environments meets clear performance and testing criteria for reliable, high‑frequency operation.
