Description
Belden 1695A 877 is a 75 Ohm SDI coax (RG type: 6) designed for low-loss serial digital video performance in plenum spaces. It features an 18 AWG solid BC - Bare Copper conductor with FEP - Fluorinated Ethylene Propylene (Foam) insulation and a PVC - Polyvinyl Chloride jacket. Shielding combines Duofoil® tri-laminate tape with a 95% tinned copper braid to help maintain signal integrity for digital video signals.
