The JBX42027 80-meter LC/APC to LC/UPC duplex single mode fiber patch cable represents premium connectivity for enterprise-grade fiber optic networks. Designed for professionals who demand reliability and performance, this cable combines advanced fiber technology with comprehensive compliance certifications. **Technical Excellence** This duplex patch cable incorporates two LC connectors—one APC (Angled Physical Contact) and one UPC (Ultra Physical Contact)—enabling flexible network architecture. The 9/125 micron single mode core with G.657.A1 bend-insensitive fiber reduces installation challenges while maintaining signal integrity over 80 meters. Measured attenuation of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensures minimal signal loss across multiple wavelengths, supporting diverse optical transmission technologies. **Performance Specifications** Insertion loss remains exceptionally low at ≤0.35dB (typically 0.15dB), with return loss exceeding 20dB—well above industry minimums. The 1.8mm outer diameter jacket accommodates tight routing while the riser-rated (OFNR) yellow polyvinyl chloride provides fire safety in building plenum spaces. All connectors undergo attenuation testing per ANSI/TIA/EIA-455-171-A standards. **Compliance & Reliability** TAA (Trade Agreements Act) compliance makes this cable suitable for government and institutional procurement. RoHS/ELV certification ensures environmental responsibility without compromising performance. The 90-day limited warranty protects your investment, while free standard shipping on orders exceeding $99 reduces acquisition costs. **Applications** Ideal for data centers, enterprise networks, telecommunications infrastructure, and institutional facilities requiring high-performance fiber connectivity. The 80-meter length suits backbone cabling, inter-building connections, and distribution systems where distance and bandwidth are critical. **Availability & Custom Options** Available for immediate shipment from multiple US distribution centers (Danville CA, Fort Worth TX, Beaufort SC), with custom length options available for specialized installations. Ships in protective 10x10x10 packaging ensuring damage-free delivery.
