The JBX86188 SC/ST Duplex Singlemode Fiber Patch Cable is engineered for demanding telecommunications and data center applications where signal integrity and compliance are non-negotiable. This 6-meter cable combines professional-grade construction with exceptional optical performance, making it the ideal choice for system integrators, network administrators, and telecom professionals. **Superior Optical Performance:** Utilizing 9/125 singlemode fiber with G.657.A1 glass composition, this cable delivers outstanding signal transmission characteristics. The insertion loss specification of ≤0.35dB (0.15dB typical) ensures minimal signal attenuation, while the return loss of ≥20dB prevents signal reflections that could degrade network performance. Attenuation ratings of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm meet or exceed industry standards. **Regulatory Compliance:** TAA compliance ensures this cable meets government procurement requirements for federal and GSA contracts. RoHS (2002/95/EC) and ELV directive compliance guarantee environmentally responsible manufacturing. The cable is tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, providing independent verification of performance. **Robust Construction:** The 1.8mm outside diameter duplex configuration provides durability while maintaining flexibility for installation in tight spaces. Riser-rated OFNR jacketing offers fire-safety compliance for vertical cable runs in multi-story buildings. The Type A to B crossover polarity configuration represents the industry standard for duplex patch cords, ensuring compatibility with existing infrastructure. **Practical Advantages:** - Ready-to-use 6m length eliminates custom splicing and associated delays - SC/UPC and ST/UPC connectors provide excellent mating repeatability - Available in custom lengths for specialized applications - 90-day limited warranty provides peace of mind - Ships free on orders over $99 from multiple U.S. distribution centers **Applications:** Ideal for connecting fiber switches, transceivers, patch panels, and optical test equipment in data centers, telecom facilities, and enterprise networks. Suitable for backbone connections, inter-equipment links, and high-speed LAN implementations where single-mode fiber performance is required.
