Three-Channel Direct Burial Hybrid Camera Cable



Direct Burial Construction - features a polyethylene outer jacket and water blacking tape

Low-Loss 9u Single-Mode Fiber- high-bandwidth, low-loss type fiber for high data rates

Color Coded Copper Sub Groups - copper elements are color stiped for identification

Numerically Printed Fiber Elements- simplex fibers are numbered for identification

High Tensile Strength Tight Buffer - tripple the tensile strength for added durability

Clark’s HFC3DB is a composite cable that is specifically designed for the distribution of all the copper and fiber elements required for three SMPTE hybrid fiber camera positions within a single cable. Each shielded copper group contains two 18AWG auxiliary conductors and two 24AWG signal conductors with a drain wire for shield termination. The fiber elements consist of six individual simplex single-mode breakout cables that are numerically printed for identification. To enable installation in direct burial applications, the HFC3DB has a water blocking tape and a polyethylene outer jacket.
