The JBX88252 1.5m ST/ST duplex singlemode fiber patch cable represents the gold standard in fiber optic connectivity for professional network installations. Engineered with precision, this cable combines cutting-edge technology with proven reliability to support mission-critical applications in telecommunications, data centers, and enterprise networks. **Technical Excellence** This singlemode patch cable utilizes a 9/125 micron core diameter with G.657.A1 glass fiber composition, optimized for long-distance, low-loss signal transmission. The cable achieves exceptional performance metrics: insertion loss of ≤0.35dB at 0.15dB typical and return loss ≥20dB, ensuring minimal signal degradation. Operating at both 1310nm and 1550nm wavelengths with attenuation rates of 0.25dB/km and 0.35dB/km respectively, this cable meets the stringent requirements of ANSI/TIA/EIA-455-171-A-2001 standards. **Superior Construction** The duplex configuration features ST/UPC connectors in Type A to B crossover polarity—the industry standard for most duplex patch applications. The 1.8mm outside diameter ensures compatibility with standard conduit and cable management systems, while OFNR (riser-rated) jacketing provides flame resistance and safety compliance for indoor installations. The blue jacket aids in visual identification and organization within complex network environments. **Compliance & Reliability** This patch cable meets all TAA (Trade Agreements Act) requirements and complies with RoHS/ELV (Restriction of Hazardous Substances) directives, including EU directive 2002/95/EC. Manufactured in Taiwan, the United States, or China with consistent quality standards, each cable includes a 90-day limited warranty ensuring peace of mind. **Practical Applications** Ideal for telecommunications networks, fiber-to-the-premise (FTTP) installations, data center connectivity, campus networks, and laboratory testing environments. The 1.5m length provides optimal flexibility for interconnecting patch panels, network equipment, and optical testing instruments without excess cable clutter. **Customization & Availability** Custom lengths are available to accommodate specific installation requirements.
