3 Ch. SMPTE 311M Hybrid: Direct Burial - HFC3DB
HFC3DB
Clark Wire & Cable’s HFCDB is a precision engineered SMPTE 311M cable designed for use in permanent installation applications. With two single-mode fibers for multiplexed video, audio and data, the HFCDB delivers exceptionally low-loss for HD camera to CCU interconnects. All copper conductors are insulated with a polyethylene dielectric for exceptional heat and current leakage resistance. For added durability, the two single-mode fiber elements are coated with a high tensile strength CPE tight buffer that achieves three times the tensile strength as compared to typical PVC tight buffer compounds. For direct burial applications, the HFCDB features a puncture resistant polyethylene outer jacket and a water-blocking tape that wraps around the inner core to provide an additional level of protection by absorbing moisture in the event the jacket is penetrated.
