The JBX88375 ST/ST duplex singlemode fiber patch cable represents the ideal solution for organizations requiring reliable, standards-compliant optical connectivity. This meticulously engineered 3-meter cable combines precision manufacturing with proven performance specifications to support mission-critical network operations. **Technical Excellence**: Built with 9/125 singlemode fiber core and G.657.A1 glass composition, this cable exhibits outstanding attenuation characteristics at standard telecom wavelengths (1310nm: 0.25dB/km and 1550nm: 0.35dB/km). The insertion loss specification of ≤0.35dB with typical performance of just 0.15dB ensures minimal signal degradation across extended runs, while the ≥20dB return loss maintains signal integrity in demanding applications. **Regulatory Compliance**: TAA-compliant and fully RoHS/ELV certified per EU Directive 2002/95/EC, this cable meets procurement requirements for government and enterprise customers worldwide. OFNR riser-rated jacketing ensures installation safety in vertical cable runs and plenums. **Practical Design Features**: The distinctive purple jacket enables quick visual identification in complex cable environments, reducing troubleshooting time and installation errors. ST/UPC connectors with Type A to B crossover polarity configuration provide plug-and-play compatibility with standard network equipment. The compact 1.8mm outside diameter facilitates efficient cable management and routing flexibility. **Quality Assurance**: Attenuation performance is tested and verified in accordance with ANSI/TIA/EIA-455-171-A standards, backed by a comprehensive 90-day limited warranty. Custom length availability accommodates specific deployment requirements beyond the standard 3-meter offering. **Applications**: Ideal for telecommunications facilities, data center interconnections, enterprise LAN backbone deployments, and any environment requiring single-mode optical connectivity with superior performance characteristics.
