cables that deliver high performance in demanding applications



for transit infrastructure applications

Marmon IEI’s data, voice, and network cables are leading the specialized cable industry in major rail transit datacom projects. Our HUB-Link® product line has worked on several projects that include the Silver Line Dulles Metrorail, HART elevated rail line, Santa Clara Valley BART Extension (SVBX), New York City 53rd Street Tunnel, and many more.

HUB-Link® includes a group of LSZH telecommunications cables designed to support the New York City Transit Authority specification (NYCT Telecommunication Cable Rev. 7 [TC-7], Dec. 3, 2009). These telecommunications cables are routed and terminated through the subway system. HUB-Link® rail transit cables are designed to resist the rugged conditions of the underground and above-ground environments, including temperature extremes, moisture, salt air, fluids, rodent damage, and sunlight while meeting strict specifications for flame propagation, smoke density, and toxicity in the event of a fire.

In addition to HUB-Link® communications cables, Marmon IEI offers many other cabling solutions for the transit infrastructure. Cable types include case wire, signal cable, type XHHW-2 and RHW-2 cables, tray cables, and more.
