    Specifications for SPARO Cables



    The specifications listed below are the cables that will be used to satisfy the requirements of SPARO's cabling. Some cables are already built and some cables will be built using existing VIPER cables. The rest will be ordered from Belden and the Belden catalog number is listed. All cables are PLENUM grade, TEFLON insulated wire with STRANDED TINNED COPPER conductors. All are FOIL SHIELDED and all but the 89418 and 88778 series are BRAID SHIELDED as well for additional interference screening and physical strength. The 88778 consists of INDIVIDUALLY SHIELDED TWISTED PAIRS.
