Hub-LINK®, Transit Communications cables are designed to support the New York City Transit Authority (NYCT). These telecommunications cables are used in various telephone circuits and general communications services throughout the outside plant transit system. These cables are multiple-twisted- pair cables with solid copper conductors insulated with solid polyolefin surrounded by water-swellable tapes, low-smoke, low-toxicity, non-halogen inner and outer jacket with a 5-mil copper shield. These cables are also used in various outside and tunnel applications, placed in conduits, closets, and other enclosures.
Underwriters Laboratories: C(UL)US Type CMR-LS, CMG-LS, and CM-LS These products have undergone extensive physical testing per UL 444 (Communications Cables) and burn testing per UL1666 (test for flame propa- gation height of electrical cables installed vertically in shafts). They have also successfully passed the Limited Smoke testing to FT4/IEEE 1202 to carry the additional “LS” marking which is above and beyond NYCT TC-7 requirements.
Additional Physical/Smoke/Toxicity Testing (TC-7): These products have been subjected to Fluid Immersion (Lubricating and Hydraulic Oil, Gas, and Water), Tear Resistance, Smoke Generation (Flaming/Non-Flaming), Smoke and Toxicity Index, Acid Gas, Halogen Content, Horizontal Abrasion, Light Absorption (UV), Environmental Stress Crack Resistance, Cold/Hot Bend, Cable Impact, Water Absorption, Jacket Shrink-back, and Heat Distortion.
Electrical Testing per ANSI/TIA-568-C.2 (Category 3): Conductor Tolerances, DC Resistance, Attenuation, Impedance, Capacitance, Mutual Capacitance, Capacitance Unbalance (pair to pair), Capacitance Unbalance (pair to ground), Crosstalk, Insulation Resistance, Conductor-to-Conductor Proof Test, Core-to- Shield DC Proof, Shield Resistance, and Continuity.
