The JBX89157 SC/SC duplex singlemode fiber patch cable represents a professional-grade solution for organizations demanding reliable, high-performance fiber optic connectivity. This 5-meter cable features precision-engineered 9/125 singlemode cores with G.657.A1 glass fiber specification, meeting stringent industry standards for long-distance signal transmission. Key Technical Specifications: This duplex patch cable achieves exceptional attenuation performance at both primary wavelengths: 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. Insertion loss measures ≤0.35dB (typical 0.15dB), while return loss exceeds 20dB—ensuring pristine signal integrity. Testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent quality across all units. Design and Construction: The 1.8mm outside diameter accommodates standard fiber management systems, while riser-rated (OFNR) jacketing provides fire safety compliance. The distinctive purple jacket facilitates rapid cable identification and reduces installation errors in multi-cable environments. SC/UPC connectors with Type A to B crossover configuration provide the most common duplex patch cord polarity. Compliance and Certification: TAA compliant certification qualifies this cable for U.S. government and federal procurement programs. RoHS/ELV compliance (EU directive 2002/95/EC) ensures environmental responsibility. Manufacturing in Taiwan, the United States, and China provides supply chain flexibility and competitive pricing. Applications: Ideal for data centers, telecommunications facilities, campus networks, and enterprise installations requiring single-mode fiber performance. Suitable for applications demanding low insertion loss and high return loss specifications. Customization and Availability: Available in custom lengths to meet specific installation requirements. Free standard shipping on orders exceeding $99. Ships from multiple U.S. locations: Danville, CA; Fort Worth, TX; and Beaufort, SC. Backed by comprehensive 90-day limited warranty covering defects in materials and workmanship.
