The JBX88119 SC/ST 90-meter duplex singlemode fiber patch cable represents a premium solution for professional network connectivity and telecommunications infrastructure. Manufactured to exacting standards, this cable combines superior optical performance with practical design features that meet the demands of modern data centers, telecommunications facilities, and enterprise networks. Optical Performance and Specifications: This singlemode fiber cable features a 9/125 micron core with G.657.A1 grade glass fiber, specifically designed for applications requiring low attenuation and minimal signal degradation over extended distances. The cable achieves insertion loss of ≤0.35dB with typical performance of 0.15dB, and maintains return loss of ≥20dB, ensuring signal integrity in bidirectional communications. Operating across both 1310 nm and 1550 nm wavelengths, it delivers consistent performance with attenuation rates of 0.25 dB/km and 0.35 dB/km respectively, making it ideal for CWDM and DWDM applications. Connector Configuration: The SC/UPC to ST/UPC connector arrangement with Type A to B crossover polarity provides industry-standard compatibility and simplified installation. The duplex configuration supports full-duplex transmission, enabling simultaneous bidirectional communication across a single cable assembly. Compliance and Safety: TAA (Trade Agreements Act) compliance ensures this cable meets federal procurement standards for government and institutional buyers. RoHS/ELV certification guarantees compliance with environmental regulations, eliminating hazardous substances. The riser-rated (OFNR) PVC jacketing provides flame resistance suitable for use in building risers and plenum spaces, meeting stringent fire safety codes. Durability and Construction: With a compact 1.8mm outside diameter and plastic accessories rated for standard handling, this cable balances flexibility with durability. The 90-meter length accommodates medium to long-distance runs while maintaining manageable weight and coil characteristics. Performance has been verified according to ANSI/TIA/EIA-455-171-A-2001 standards, ensuring reliability across installations. Applications: Ideal for telecommunications networks, data center interconnects, campus backbone installations, and broadcast facilities requiring reliable single-mode transmission. The 90-day limited warranty provides confidence in long-term performance and investment protection.
