HDMI series

HDMI Cable Series from the GCR Brand

Cable and Cord: Definitions According to GOST 15845-80

GCR offers both types of products. The difference between them is defined by the standard and determined by their intended operating conditions:

• Cable — designed for permanent installation. The outer jacket is reinforced and provides protection against external influences. Suitable for installation inside walls, cable ducts, and outdoor areas.
• Cord — designed for flexible connections. It is more flexible and intended for frequent reconnection and movement of equipment.

Each model is designed for a specific application: permanent installation or flexible connection.

Technologies and Specifications

GCR cables support HDMI 2.1 with data transfer rates of up to 48 Gbit/s. This is a standard requirement for modern high-resolution video.

GCR cables support:

• 8K at 60 Hz and 4K at 120/144 Hz;
• HDR, eARC, VRR, ALLM, QMS, QFT;
• HDCP 2.2 and 2.3 content protection.

Specifications are confirmed by testing each production batch.

Materials

Budget cables often use copper with impurities, which increases conductor resistance. GCR uses oxygen-free copper (OFC): fewer impurities mean lower resistance and a more stable signal.

The contacts are plated with 24K gold. The coating protects against oxidation and maintains stable impedance over long-term use.

Professional series cables feature triple shielding:

• foil shielding on each differential pair — reduces crosstalk inside the cable;
• an overall foil shield — protects against external high-frequency interference;
• a braid (copper or steel, depending on the model) — suppresses low-frequency interference and provides additional mechanical reinforcement.

The GCR PRO series is equipped with ferrite filters to suppress high-frequency noise.

GCR cables are designed to operate near power lines, server equipment, and industrial installations.

Series

The GCR range includes more than 50 models. The series differ in design and intended application.

Manufacturing

The manufacturing facility is the Pskov Plant of Computer and Mobile Cable (PZKMK). ISO 9001 certified.

Production stages:

1. Drawing copper wire from rod.
2. Extrusion of insulation and outer jacket.
3. Application of braid and multilayer shielding.
4. Laser marking.
5. Electrical and mechanical testing.

Every cable undergoes bench testing. Critical production operations are subject to continuous rather than sampling-based quality control.

For Businesses and Government Customers

GCR is a supplier with confirmed Russian manufacturer status. Registration in the GISР registry allows participation in tenders under Federal Laws 44-FZ and 223-FZ without additional localization confirmation.

Shipments are made directly from a warehouse in Russia, without intermediaries. GCR engineers help select cables for the customer's infrastructure based on distance, environmental conditions, and bandwidth requirements.

Brand Philosophy

GCR does not build an ecosystem around its products. The company's goal is to make a cable that works reliably under any conditions.

The reliability of an HDMI cable is determined by its materials, shielding, and conductor length. GCR designs these parameters for specific use cases rather than adding features solely for marketing purposes.

A cable that works without failures requires no attention. Only the image and sound remain.

Choosing a Cable

The catalog lists all models along with their technical specifications: length, connector type, and series. Filters help select the right cable for a specific application.

For non-standard installations, you can contact GCR engineers with a request. Selection is based on three parameters: distance, environmental conditions, and bandwidth requirements.
