The JBX43627 80-meter FC/APC to ST/UPC Simplex Singlemode Fiber Patch Cable represents a premium solution for professional fiber optic network installations requiring extended cable runs. This carefully engineered cable combines superior optical performance with robust construction standards. Technical Excellence: The cable features a 9/125 singlemode fiber core aligned with G.657.A1 specifications, engineered specifically for minimal signal degradation over extended distances. At 1310 nm, the cable delivers 0.25 dB/km attenuation, while at 1550 nm it achieves 0.35 dB/km. The measured insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure optimal signal integrity for critical applications. Connector Compatibility: The FC/APC to ST/UPC configuration provides flexibility in connecting disparate network equipment. FC/APC connectors offer superior return loss characteristics, while ST/UPC connectivity ensures broad compatibility with existing infrastructure. Durability and Compliance: Constructed with 1.8mm outside diameter and protected by riser-rated (OFNR) yellow PVC jacketing, this cable meets UL and building safety standards. The yellow color facilitates easy identification in complex cable installations. Full RoHS/ELV compliance and TAA certification make this cable suitable for government and enterprise procurement requirements. Practical Advantages: Manufactured in Taiwan, US, or China with stringent quality controls, the cable ships via free standard shipping on orders exceeding $99. The 90-day limited warranty provides peace of mind for installations. Available in custom lengths to eliminate waste and reduce installation costs. Ideal Applications: Data center backbone connections, telecommunications infrastructure, long-haul campus networks, and any scenario requiring reliable single-strand singlemode fiber transmission over 80 meters or beyond.
