The JBX87198 35m SC/ST Duplex Singlemode Fiber Patch Cable represents a professional-grade solution for telecommunications, data center, and enterprise network infrastructure. Manufactured with precision engineering, this cable delivers the performance and reliability that demanding network environments require. **Technical Specifications:** This duplex fiber patch cable features a 9/125 singlemode core with G.657.A1 glass fiber composition, specifically engineered for long-distance signal transmission. The SC/UPC to ST/UPC connector configuration provides Type A to B crossover polarity—the most common and reliable standard for duplex patch cord applications. At 35 meters in length, this cable accommodates medium-distance runs within data centers, server rooms, and telecommunications equipment installations. **Performance Metrics:** Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, the cable delivers exceptional optical performance. Insertion loss measures ≤0.35dB (with typical performance at 0.15dB), while return loss exceeds 20dB. Attenuation rates of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm ensure minimal signal degradation across multi-wavelength applications. **Safety and Compliance:** The OFNR-rated riser jacketing provides superior fire safety for in-building installations while maintaining a compact 1.8mm outside diameter for easy routing through cable trays and conduit. Full RoHS/ELV compliance and TAA certification ensure regulatory adherence for government and enterprise procurement programs. The cable is manufactured across multiple facilities in Taiwan, the United States, and China, maintaining consistent quality standards. **Applications and Use Cases:** Ideal for connecting telecommunications equipment, network switches, routers, and optical multiplexers. Commonly deployed in campus backbone networks, data center interconnections, and high-speed LAN environments. The singlemode construction supports both short-reach and long-distance transmission scenarios within building infrastructure. **Warranty and Support:** Backed by a 90-day limited warranty ensuring peace of mind. Custom lengths available for specialized installations. Ships from multiple U.S. locations (Danville, CA; Fort Worth, TX; Beaufort, SC) with free standard shipping on orders exceeding $99. **Care and Maintenance:** Handle connectors with care to prevent dust contamination. Store in a dry environment and avoid excessive bending. Inspect connectors periodically for cleanliness and proper connection integrity to maintain optimal performance.
