Audio/video optical cable TDX75A-SNF4PZL-BURB

dataRJ45S/FTP

Product Application
This cable is designed for structured cabling in commercial and industrial networks. It complies with GB 50311, ISO/IEC 11801 and ANSI/TIA-568.2-D. With tested bandwidth up to 1.2 GHz (Fa-class/Cat.7A), it supports voice, data and analog/digital audio‑video transmission in backbone, horizontal and equipment cabling.

Product Features
Four individually foil-shielded twisted pairs (S/FTP) plus an overall foil shield; solid AWG22 copper conductors; tested bandwidth up to 1200 MHz; LS0H/FRNC jacket options meeting IEC 60332-1 flame requirements; suitable for indoor installations where EMI immunity and high data rates are required.

Product Performance

• Transmission bandwidth: 1.0 GHz (tested up to 1.2 GHz)
• Conductor DC resistance (20°C): 73.2 Ω/km
• Capacitance (approx.): 42 pF/m
• Characteristic impedance: 100 ± 5 Ω
• Coupling attenuation: ~85 dB
• NVP (Nominal Velocity of Propagation): ~80%
• Tensile strength: ≤ 110 N
• Bending radius: pulling ≥ 70 mm; fixed ≥ 34 mm
• Temperature range: installation 0°C to +50°C; operating -20°C to +60°C
• Halogen, smoke and flame standards: GB/T 17650, IEC 60754-1/-2, GB/T 18380.12, IEC 60332-1, GB/T 17651, IEC 61034-1/-2

Construction & Mechanical Details
Each of the four pairs is individually foil-shielded with a consistent twist geometry to reduce internal crosstalk and improve differential-mode transmission. An overall foil wrap provides additional EMI protection. Conductors are solid copper AWG22 for stable electrical performance and low insertion loss over long runs.

Advantages

• Multi-layer shielding (pair + overall) for strong EMI immunity in environments near power distribution, UPS or HVAC systems.
• Solid AWG22 conductors deliver stable electrical characteristics optimal for backbone and server-room runs.
• Backward compatibility with RJ45-based infrastructure (use GG45/TERA where required) for integration into existing networks.
• Jacket and mechanical properties support routing in ceilings, raised floors, conduits and backbone ducts while meeting safety standards.

Use Scenarios

• Telepresence and AV links in executive boardrooms requiring shielded, low-latency connections for 4K/8K streaming and conferencing.
• Enterprise backbone and financial server wiring where EMI from power equipment is present and 10 Gbps over 100 m is required.
• Surveillance and control rooms (e.g., airport operations) preferring shielded copper for lower latency and simplified maintenance compared with fiber.

FAQ

• Does this cable support full 10GBase-T over 100 m? — Yes; TDX75A-4P meets Cat.7A specifications and supports 10 Gbps over 100 m for full-length channels.
• What connector types are supported? — Compatible with GG45 and TERA; can interoperate with RJ45-based equipment where appropriate Cat6A-rated components are used.
• Is the cable suitable near power sources or transformers? — Yes; pair-level and overall shielding make it appropriate for EMI-prone environments.
• Can this cable be bundled with other shielded cables? — Yes; shielding minimizes crosstalk and allows tight bundling in trays and raceways without performance degradation.
• Are special jacket materials available? — PE, LS0H/FRNC and other jackets can be provided for plenum or industrial requirements on request.
