The JBX88289 ST/ST duplex singlemode fiber patch cable represents a reliable solution for professional optical networking applications. With a 7-meter length and ST/UPC connectors configured for Type A to B crossover operation, this cable delivers the performance characteristics demanded by modern telecommunications infrastructure. Technical Excellence: Engineered with 9/125 singlemode fiber core and G.657.A1 glass specifications, this cable achieves exceptional optical performance. Attenuation testing conducted per ANSI/TIA/EIA-455-171-A-2001 confirms insertion loss of ≤0.35dB (0.15dB typical) and return loss exceeding 20dB. At 1310nm wavelength, attenuation measures 0.25dB/km, while 1550nm performance reaches 0.35dB/km—specifications that support both short-reach and long-distance transmission requirements. Compliance and Certification: This patch cable carries TAA compliance, making it eligible for government and public sector procurement. RoHS/ELV certification and EU Directive 2002/95/EC compliance demonstrate commitment to environmental responsibility. The OFNR riser-rated jacketing ensures safe installation in plenum spaces and vertical cable runs, meeting building code requirements. Design and Identification: The distinctive green jacket facilitates easy cable identification in congested data center environments, reducing troubleshooting time and installation errors. The compact 1.8mm outside diameter integrates seamlessly with standard fiber patch panels and cable management infrastructure. Duplex configuration supports simultaneous bidirectional communication, essential for modern full-duplex optical networks. Applications: Ideal for data centers, telecommunications closets, network backbone connections, and enterprise LAN infrastructure. Compatible with switching equipment, routers, optical multiplexers, and other ST-equipped network devices. Customization Available: Organizations requiring non-standard lengths can request custom configurations to match specific installation requirements. Warranty and Support: Protected by a 90-day limited warranty with convenient shipping from multiple US distribution centers (Danville CA, Fort Worth TX, Beaufort SC).
