  Radically different from typical industry products but with the same performance characteristics of traditional SMPTE 311 cables, the Gepco® Brand flexible HDC720HD 7.8 mm hybrid fiber cable is 16 percent smaller and 40 percent lighter in design.

The revolutionary construction of the HDC720HD starts with replacing the typical heavy steel strength member with a Kevlar® strength member that has the same pull strength of steel, but is lighter and more flexible. Unlike steel, Kevlar expands and contracts at the same rate as the glass members during temperature extremes, keeping the elements in the cable aligned reducing migration. Using Kevlar in place of steel also means the cable has virtually no memory, making the cable easier to pay off, lay flat and wind back up on the drum.

For further durability, the HDC720HD utilizes endinsensitive
fiber elements with very low attenuation and a bend radius of 0.2 mm—versus 2.0 mm for traditional single-mode fiber—in a breakout style with additional Kevlar protection around the individual fibers.

In the HDC720HD, the typical outer braid is replaced with two 18 AWG drain wires and a foil shield that allow the cable to be more flexible, lighter and smaller in diameter. The power conductors consist of two 16 AWG conductors so you can still achieve the same distance a regular SMPTE 311 cable performs to. The master jacket of HDC720HD is polyurethane material with a glossy finish that reduces the pickup of dirt and debris from outside applications, making it easier to keep clean.
