BL-4855R-BK-FT - Overview

Belden 4855R is a 12 GHz, 4K UHD Precision Mini RG-59, 75 Ohm Video Cable. It's 23 AWG and features a solid 0.023 silver-plated copper conductor, gas-injected foamed high-density polyethylene insulation, with Duofoil® bonded to the core plus a tinned copper braid shield (95% coverage) in a PVC Jacket.

Belden 4K UHD Coax Cables for 12G-SDI maximize 4K signal transmission distance over a single coax, minimizing weight and space utilization compared to multi-link solutions. This solution provides significant headroom and guarantees -15 dB return loss from 4.5 to 12 GHz.

Applications:
Ultra-High Definition Digital Video
4K Single-link 12 Gb/s UHDTV
4K D-Cinema
8K Quad-link UHDTV
HD-SDI 1080p

  • Features:

    • Faster Installation: Using Belden's single-link solution saves time and is significantly lighter than dual or quad-link configurations
    • Optimized Design: On Belden 4K UHD Coax Cables for 12G-SDI, the inner foil is bonded to the core to eliminate bunching when installing 1-piece connectors. The outer foil is bonded to the jacket for a quicker, one-step stripping process
    • Superior Performance: The 4K UHD coax cable for 12G-SDI are superior in performance and engineered to optimize transmission distance, the cables exceed the SMPTE Return Loss (RL) specifications for UHDTV
    • Supports 12 GHz: Belden 4K UHD Coax Cables for 12G-SDI are capable of supporting 12 GHz bandwidth and enable a single-link configuration to transmit 4K
