1 TECHNICAL SPECIFICATION 4 PAIR UTP CABLE (ENHANCED CATEGORY 5) PVC (CM Grade) Page 1 of 6

2 1. SCOPE This specification is based on the specifications of UL 444, ANSI/TIA/EIA-568-B.2, UL 1685 and covers the requirements for Unshielded Twisted Pair (UTP) cables of 100 Ω, Enhanced Category 5 (Cat.5E) for Wideband Technology. 2. PRODUCT SPECIFICATION 2.1 CONSTRUCTION CONDUCTORS Each conductor shall be solid Plain Annealed Copper wire, circular in cross-section, uniform in quality and free from defects. The diameter of each conductor shall be AWG INSULATION Each conductor shall be insulated with solid high density Polyethylene. It shall be applied uniformly around the conductor with a minimum concentricity of 90%. The nominal insulation diameter shall be 0.88mm±0.03mm PAIRS Two insulated conductors, designated "A" and "B" shall be uniformly twisted together to form a pair. The insulation shall be coloured and striped longitudinally, as per Table 1. The stripe colouring shall not be removable by normal stripping and wiring operations.

3 2.1.4 CABLE CORE ASSEMBLY Pair 1 to 4 shall be uniformly twisted together in sequence 1, 2, 3 and 4 on a torsional twist machine so as to impact a further twist into the pairs SHEATH The material shall, as a minimum, meet the requirements of UL 444. The sheath shall be applied over the cable assembly by an extrusion tubing technique, being close fitting, but not adhering to the insulation, and readily removable for installation termination. The PVC sheath shall have a minimum wall thickness of 0.34mm and nominal 0.4mm. The acceptable maximum cable diameter shall be 5.0mm. The sheath colours are given in Table 2. Table 2 Colour Code Sheath Colour RAL Code BL Blue RAL SHEATH MARKING The cable shall be marked on the sheath to designate the transmission performance and others. The marking shall be printed through the outer sheath clearly. The specific legend requirements are given in Table 3.

The heataged tensile strength and elongation at break, measured in accordance with clause 7.3 of UL 444 shall be minimum 75% and 75% of un-aged, respectively. The insulation shrinkage, measured in accordance with clause 7.4 of UL 444, shall not exceed 9.5mm. The insulation cold bend, measured in accordance with clause 7.5 of UL 444, shall show no visible cracks SHEATH The unaged tensile strength and elongation, measured in accordance with clause 7.8 of UL 444 shall be minimum 17.24MPa and 100%, respectively. The heat-aged tensile strength and elongation, measured in accordance with clause 7.8 of UL 444 shall be minimum 75% and 50% of un-aged, respectively. Page 3 of 6
