The JBX91088 85-meter LC/ST duplex singlemode fiber patch cable represents a premium solution for mission-critical network environments requiring reliable, high-speed data transmission. This duplex cable configuration features two separate singlemode strands, each with a 9/125 micrometer core and G.657.A1 glass fiber composition, enabling simultaneous bidirectional communication. Key Performance Specifications: With insertion loss of only 0.35dB maximum (0.15dB typical) and return loss exceeding 20dB, this cable minimizes signal degradation over the 85-meter length. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure consistent performance across standard telecom wavelengths. These specifications meet rigorous ANSI/TIA/EIA-455-171-A testing standards. Construction & Compliance: The cable features a green OFNR (Optical Fiber Nonconductive Riser) rated jacket with a 1.8mm outside diameter, engineered for fire safety in vertical runs within commercial buildings. TAA (Trade Agreements Act) compliance makes this cable eligible for government and institutional procurement. Full RoHS/ELV directive adherence ensures environmental responsibility. Connector Configuration: LC/UPC to ST/UPC connectors with Type A to B crossover polarity represent the industry-standard duplex patch cord configuration, making this cable immediately compatible with existing network infrastructure in data centers, telecom facilities, and campus networks. Applications & Use Cases: Ideal for connecting network switches, routers, and optical transceivers in enterprise environments. The 85-meter length accommodates medium-distance runs between equipment racks and distribution points. Custom length availability addresses unique installation requirements. Warranty & Support: Every cable includes a 90-day limited warranty. Ships with free standard shipping on orders exceeding $99, with availability from multiple US distribution centers (Danville CA, Fort Worth TX, Beaufort SC).
