FAQ

Q: What is the primary advantage of multi-pair twisted construction?
A: Twisting eliminates electromagnetic interference (EMI) by canceling out induced currents, while multi-pair design allows simultaneous transmission of multiple signals in a single cable.

Q: How does pair twist rate affect performance?
A: A consistent twist rate (typically 1-2 twists per inch) ensures balanced impedance and minimizes crosstalk between adjacent pairs.

Q: What shielding options are available for these cables?
A: Common options include foil shielding (100% coverage), braided shielding (60-95% coverage), and hybrid foil+braid for maximum EMI/RFI protection.

Q: What AWG sizes are standard for instrument cables?
A: 24 AWG is most common for balanced audio signals, while 22 AWG may be used for power/data hybrid applications.

Q: Can these cables be used in outdoor installations?
A: Yes, with UV-resistant jackets and moisture-blocking designs meeting IEC 60529 IP66 standards for harsh environments.

Q: What's the maximum recommended run length?
A: For 24 AWG pairs, runs up to 1000 feet are typical before signal degradation, depending on frequency and shielding quality.

Q: How do I terminate multi-pair cables?
A: Use modular plugs (RJ45) or terminal blocks with proper color-coding (T568A/B standards) to maintain pair integrity.
