The JBX88384 ST/ST singlemode fiber patch cable represents professional-grade connectivity designed for critical network infrastructure. Spanning 15 meters, this duplex configuration provides dual fiber strands for redundant or bi-directional communication paths, making it ideal for complex network architectures. Key Technical Specifications: This cable features a 9/125 singlemode core with G.657.A1 high-performance glass fiber, engineered for wavelengths at both 1310 nm (0.25 dB/km attenuation) and 1550 nm (0.35 dB/km attenuation). The exceptionally low insertion loss rating of ≤0.35dB ensures minimal signal degradation over the 15-meter span, while the return loss specification of ≥20dB guarantees reliable impedance matching. Design and Compliance: The 1.8mm outside diameter jacket is riser-rated (OFNR), meeting building safety codes while providing durable protection. Manufactured with RoHS/ELV compliance and EU directive 2002/95/EC certification, this cable meets stringent environmental and safety standards. The Type A to B crossover polarity is the industry-standard configuration for duplex patch cord applications. Applications: Ideally suited for telecommunications facilities, data center interconnects, backbone networks, and enterprise fiber installations where signal integrity and compliance are paramount. The purple jacket aids visual identification in complex cable management environments. Warranty and Support: Backed by a 90-day limited warranty and available in custom lengths to meet specific deployment requirements. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Standards-tested per ANSI/TIA/EIA-455-171-A-2001 for reliability assurance.
