The JBX88334 65-meter ST/ST duplex singlemode fiber patch cable represents the ideal solution for professional-grade fiber optic network installations. This high-performance cable is manufactured to exacting standards and features a Type A to B crossover polarity configuration, making it the most common specification for duplex patch cord applications. **Superior Technical Performance** With a 9/125 singlemode core and G.657.A1 glass fiber construction, this cable delivers exceptional optical characteristics. The insertion loss of ≤0.35dB (typical 0.15dB) ensures minimal signal degradation over long distances. Return loss exceeding 20dB provides reliable signal integrity, while attenuation rates of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm make it suitable for both short and long-haul applications. **Durability and Compliance** The OFNR (Optical Fiber Non-conductive Riser) rated jacketing provides fire safety compliance for vertical cable runs in commercial buildings. At just 1.8mm outer diameter, the cable fits easily through conduits and tight installation spaces without compromising durability. The plastic accessory construction and RoHS/ELV compliance ensure environmental responsibility and regulatory adherence. **Practical Applications** This duplex patch cable excels in telecommunications networks, enterprise data centers, ISP backbone installations, and medical imaging facilities. The 65-meter length eliminates the need for additional splicing in medium-distance runs, reducing potential failure points and maintenance costs. **Value and Warranty** Manufactured across Taiwan, US, and China facilities, the JBX88334 is TAA compliant for government and institutional purchases. It includes a 90-day limited warranty and qualifies for free standard shipping on orders exceeding $99. Custom lengths are available upon request for specialized installations. **Testing and Standards** Attenuation testing complies with ANSI/TIA/EIA-455-171-A-2001 standards, ensuring third-party verification of performance specifications. This certification provides confidence in network reliability and long-term performance.
