HDMI 2.1 Cable 8K 48Gbps eARC HDR10+ | SKW 5001-1A Series

HDMI 2.1 Bandwidth and Feature Support

The SKW 5001-1A series is an Ultra High Speed HDMI cable built to the HDMI 2.1 specification, delivering 48Gbps aggregate bandwidth across all signal paths. This bandwidth ceiling supports uncompressed 8K video at 60 frames per second and 4K at 120fps — the two resolution-refresh combinations that define current-generation home theater and professional display markets.

48Gbps Signal Architecture

The cable carries HDMI 2.1 feature sets including Dynamic HDR with HDR10+ frame-by-frame metadata, Variable Refresh Rate (VRR) for gaming and visualization applications, Auto Low Latency Mode (ALLM), and Quick Frame Transport (QFT) which reduces display latency in multi-source switching environments. Enhanced Audio Return Channel (eARC) enables lossless multichannel audio formats — Dolby TrueHD, DTS-HD Master Audio, and Dolby Atmos object-based streams — to pass from display to soundbar or receiver over the same cable that carries video.

HDR10+, VRR, and ALLM Implementation

Gold-plated HDMI contacts provide corrosion-resistant mating surfaces that maintain low contact resistance over thousands of connect-disconnect cycles, critical for rental equipment, trade show displays, and permanently installed commercial signage where cables are frequently re-terminated. The braided outer jacket resists abrasion from cable-pull routing through conduit, wall plates, and ceiling-mounted display arms.

Enhanced Audio Return Channel (eARC)

Signal integrity at 48Gbps requires controlled impedance across all 19 pins. The 5001-1A achieves this through precision-extruded dielectric insulation around each conductor pair, with overall foil plus braid shielding that attenuates EMI from adjacent power cables and wireless transmitters operating in the same cable tray.

Lossless Audio Format Passthrough

Available in multiple standard lengths, the 5001-1A series addresses the full range of installation scenarios — from short patch connections between stacked AV components to extended runs between wall-mounted displays and rack-mounted source equipment. Each length is validated for full 48Gbps throughput at its rated distance, avoiding the signal degradation that generic cables exhibit at their upper length limits.

Connector and Jacket Engineering

For distributors and AV integrators, the 5001-1A provides a single SKU family that covers consumer, prosumer, and commercial installation segments without requiring separate product lines for each market tier.
