The JBX88338 85-meter ST/ST duplex singlemode fiber patch cable represents a premium solution for professional fiber optic network installations. Built to exacting specifications, this cable combines the reliability of proven ST/UPC connectors with advanced G.657.A1 glass fiber technology designed for maximum performance in long-distance signal transmission scenarios. Key Technical Advantages: The 9/125 micron singlemode core provides exceptional bandwidth capacity suitable for high-speed data transmission up to 10Gbps and beyond. Measured attenuation of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensures minimal signal degradation over the 85-meter span. Insertion loss remains exceptionally low at 0.15dB typical (maximum 0.35dB), while return loss exceeds 20dB for signal integrity. Compliance and Safety: Full TAA compliance makes this cable suitable for government and regulated installations. RoHS/ELV directive compliance ensures environmental responsibility. The OFNR riser-rated jacketing permits installation in building plenum spaces without conduit, simplifying deployment in complex infrastructure environments. Design and Durability: The Type A to B crossover configuration follows industry-standard duplex patch cord polarity conventions, eliminating configuration confusion. At 1.8mm outside diameter, the cable offers flexibility for tight routing while maintaining structural integrity. Ships in professional 10x10x10 case packaging for secure transit. Applications: Ideal for data center backbone connections, telecommunications facilities, enterprise campus networks, and any installation requiring reliable long-distance singlemode fiber transmission. The 90-day limited warranty provides peace of mind for critical deployments. Customization Available: For specific length requirements, custom configurations are available to match exact installation specifications.
