The JBX42569 90m ST/APC to FC/UPC Duplex Singlemode Fiber Patch Cable represents the gold standard in long-distance fiber optic connectivity. Engineered for professional telecommunications, ISP networks, and enterprise data centers, this cable delivers reliable signal transmission across extended 90-meter runs with minimal loss. **Technical Excellence** Constructed with 9/125 singlemode fiber core and G.657.A1 glass fiber, this cable meets ANSI/TIA/EIA-455-171-A-2001 standards for attenuation performance. The duplex configuration supports simultaneous bidirectional transmission, while the ST/APC to FC/UPC connector pairing accommodates diverse network equipment. Typical insertion loss of 0.15dB ensures signal strength preservation, critical for long-haul applications where every decibel matters. **Installation and Compliance** The bright yellow jacket with 1.8mm diameter enables easy identification and flexible routing through crowded cable trays. OFNR (Optical Fiber Non-Conductive Riser) rating permits installation in vertical cable runs between floors. RoHS/ELV compliance and TAA certification make this cable suitable for government, military, and regulated industry deployments. **Reliable Performance** With return loss exceeding 20dB and consistent attenuation across both 1310nm and 1550nm wavelengths, this cable maintains signal integrity in multiprotocol environments. The Type A to B crossover polarity is standard for duplex installations, eliminating compatibility concerns. **Convenience and Support** Ships free on orders exceeding $99 from strategically located US facilities (California, Texas, South Carolina). Custom length options accommodate non-standard installations. The 90-day limited warranty provides confidence in long-term reliability. This professional-grade cable is the ideal choice for network technicians and system integrators demanding superior performance and regulatory compliance.
