The JBX88104 SC/ST Duplex Singlemode Fiber Patch Cable is a professional-grade networking solution engineered for telecommunications infrastructure, data centers, and enterprise network deployments. This 15-meter cable combines reliable performance with compliance certifications required by government and large organizations. **Technical Specifications:** Constructed with G.657.A1 grade glass fiber featuring a 9/125 micrometer core, this singlemode cable delivers superior signal fidelity over extended distances. The cable achieves exceptional performance metrics: insertion loss of ≤0.35dB (0.15dB typical), return loss of ≥20dB, and attenuation of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm. These specifications ensure signal integrity for high-speed data transmission at wavelengths commonly used in telecommunications. **Connector Configuration:** The SC/UPC to ST/UPC connector arrangement with Type A to B crossover polarity represents the most common duplex patch cord configuration, ensuring broad compatibility with existing network equipment. Both connector types feature UPC (Ultra Physical Contact) finish for optimal return loss performance. **Compliance & Safety:** TAA (Trade Agreements Act) compliant for government procurement requirements, this cable also meets RoHS/ELV standards and EU directive 2002/95/EC requirements. The riser-rated (OFNR) jacket provides necessary fire safety certifications for in-building vertical cable runs, making it suitable for commercial building installations. **Construction Quality:** Manufactured with precision tolerances and tested to ANSI/TIA/EIA-455-171-A-2001 standards, the cable features a durable 1.8mm diameter jacket in professional red coloring. The duplex configuration with two fiber strands in a single jacket simplifies installation and reduces cable management complexity. **Availability & Support:** Custom lengths are available for specialized applications, and the cable qualifies for free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty, the JBX88104 represents a dependable investment in network infrastructure. Ships from multiple U.S. distribution centers including Danville, CA, Fort Worth, TX, and Beaufort, SC.
