The JBX88368 85-meter ST/ST duplex singlemode fiber patch cable represents a premium solution for professional networking applications requiring extended cable runs with minimal signal degradation. This cable is specifically engineered for telecommunications, data centers, and broadcast facilities where signal integrity and reliability are non-negotiable. **Technical Excellence:** Feturing a 9/125 singlemode core configuration with G.657.A1 glass fiber, this duplex cable delivers superior performance characteristics. The insertion loss specification of ≤0.35dB (with typical performance at 0.15dB) ensures minimal signal loss across the 85-meter span. Return loss rated at ≥20dB provides excellent signal reflection control, critical for maintaining data integrity in high-speed communications. **Standards Compliance & Certification:** This cable achieves full TAA (Trade Agreements Act) compliance, making it suitable for government and regulated sector deployments. RoHS and ELV directive compliance ensures environmental responsibility and safety. Rigorous testing per ANSI/TIA/EIA-455-171-A-2001 standards confirms consistent quality and performance metrics. **Physical Specifications:** The 1.8mm outside diameter and white color provide excellent visibility and integration into professional installations. OFNR riser-rated jacketing allows for installation in air plenums and vertical runs, expanding deployment flexibility. Type A to B crossover polarity configuration—the industry standard for duplex patch cords—ensures seamless compatibility with existing infrastructure. **Wavelength Performance:** Optimized for dual-wavelength operation, this cable performs reliably at 1310 nm (0.25 dB/km attenuation) and 1550 nm (0.35 dB/km attenuation), supporting both legacy and contemporary fiber optic systems. **Custom Solutions Available:** While this 85-meter configuration addresses long-distance requirements, custom lengths are available for specialized applications. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for expedited delivery. **Warranty & Support:** Backed by a 90-day limited warranty and eligible for free standard shipping on orders exceeding $99, this cable provides both quality assurance and value. Manufactured in Taiwan, US, or China with consistent quality standards across all sourcing locations.
