cat7 pass through connectors

　　Technical Overview

　　Cat7 Pass Through Connectors are premium enterprise-grade networking interconnect components engineered to fully comply with ISO/IEC 11801 Class F and EN 50173-1 specifications, specifically designed for Cat7 SFTP (Shielded Foil Twisted Pair) patch cables. Featuring a innovative pass-through design that preserves the original twist pitch of Cat7 cables, these connectors eliminate signal distortion caused by conventional connector termination—enabling uncompromised 600MHz bandwidth and supporting 10Gbps transmission at 100m, 40Gbps at 50m, and 100Gbps at 15m. Constructed with precision-machined shielding and high-purity conductive materials, they provide superior EMI/RFI resistance for mission-critical applications in data centers, industrial automation, and high-performance commercial/residential networks worldwide. The rugged yet compact design ensures easy installation and long-term reliability, while global compliance with safety and environmental standards (RoHS 2.0, REACH, UL) makes them ideal for international export markets.
