Network Cable Synergy 21 Patch Cable RJ45 CAT8.1 2000Mhz Black S-STP S/FTP TPE/LSZH SuperFlex

The Synergy 21 Patch Cable RJ45 CAT8.1 2000Mhz Black S-STP S/FTP TPE/LSZH SuperFlex is a high-performance network cable designed for demanding data environments. It supports transmission frequencies up to 2000 MHz and uses CAT8.1 specification with an RJ45 interface, delivering very high bandwidth for modern Ethernet standards while maintaining compatibility with RJ45 ports. Constructed with S-STP (overall braided) and S/FTP (individually foil-shielded pairs plus overall braid) shielding, the cable reduces electromagnetic interference and crosstalk, improving signal integrity. The jacket and insulation combine TPE and LSZH materials to provide flexibility, durability, and low smoke zero halogen safety characteristics. The SuperFlex design improves bend resistance and routing in confined spaces.

Advantages

The cable provides very high-frequency performance up to 2000 MHz, enabling faster data throughput and lower latency for supported network equipment. Its multi-layer shielding (S-STP and S/FTP) minimizes external noise and pair-to-pair interference, which is beneficial in dense cabling or electrically noisy environments. TPE/LSZH construction balances flexibility with safety, offering easier installation in racks and conduits while reducing toxic smoke in the event of fire. The SuperFlex construction enhances durability under frequent bending and tight-radius installations.

Suitable for

• High-speed data centers and server farms
• 10G/25G/40G/100G Ethernet backbone links where RJ45 connectivity is required
• Telecommunications rooms and patch panels
• Network cabinets with limited bend radius and dense cable routing
• Environments requiring reduced fire hazards and low smoke emission

How to use

Connect one RJ45 plug to the network device and the other to the corresponding port on switches, routers, patch panels, or network interface cards. Route the cable following standard cabling practices: avoid sharp bends, maintain separation from high-voltage power lines where practical, and secure with appropriate cable management accessories to prevent strain on connectors. Verify link speed and negotiation on connected devices after installation to ensure expected bandwidth and duplex settings.

Usage recommendations

For optimal performance, keep cable runs within recommended channel lengths for the network configuration and minimize untwisting at terminations. Use grounded patch panels and properly installed shields to maintain the effectiveness of the S-STP and S/FTP shielding. In installations where fire safety is critical, the TPE/LSZH jacket reduces smoke and corrosive gases; nevertheless, follow local building codes and standards for cable routing and fire protection.
