The JBX85074 represents a comprehensive solution for telecommunications and data center professionals requiring dependable singlemode fiber connectivity. This 9-meter duplex fiber patch cable combines optical performance with practical design features suitable for both enterprise and service provider networks. Optical Performance: This cable utilizes 9/125 singlemode fiber construction, the industry standard for long-distance, high-bandwidth applications. The G.657.A1 glass fiber grade provides enhanced bend radius characteristics while maintaining excellent attenuation specifications: 1310 nm at 0.25 dB/km and 1550 nm at 0.35 dB/km. With insertion loss tested at ≤0.35dB and return loss exceeding 20dB, this cable ensures minimal signal reflection and maximum data integrity. Connector Technology: Features LC/UPC to ST/UPC connectors configured in Type A to B crossover polarity—the most common duplex patch cord configuration. Both connector types utilize Ultra Physical Contact (UPC) polished faces, delivering superior return loss performance critical for sensitive optical systems. Design & Installation: The yellow OFNR-rated jacket provides code compliance for riser installations while the 1.8mm diameter enables flexible cable management in tight spaces. The duplex configuration supports simultaneous bi-directional communication, reducing installation complexity in applications requiring separate transmit and receive paths. Compliance & Warranty: RoHS/ELV directive compliance ensures environmental responsibility. Attenuation measurements conform to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance. Backed by a 90-day limited warranty. Applications: Ideal for data centers, telecommunications infrastructure, video surveillance systems, and enterprise networks requiring reliable single-mode fiber connectivity. The 9-meter length accommodates standard patch panel to equipment spacing. Shipping: Qualifies for free standard shipping on orders exceeding $99, with inventory maintained at multiple distribution centers (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery.
