The JBX42087 80-meter LC/APC to SC/UPC Duplex Singlemode Fiber Patch Cable is a professional-grade optical interconnect solution designed for enterprises, data centers, and telecommunications infrastructure requiring reliable long-distance fiber optic transmission. **Superior Performance Specifications:** This cable features a 9/125 singlemode fiber core optimized for single-wavelength transmission over extended distances. With attenuation ratings of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, it meets stringent ANSI/TIA/EIA testing standards. The ultra-low insertion loss (typical 0.15dB, maximum 0.35dB) and high return loss (≥20dB) ensure minimal signal degradation across your 80-meter run. **Connector Technology:** The LC/APC to SC/UPC configuration provides cross-compatibility between different connector types while maintaining angled polished connector (APC) precision on the LC end and ultra-polished connector (UPC) on the SC end. Type A to B crossover polarity ensures compatibility with standard duplex network equipment configurations. **Durability & Compliance:** Constructed with G.657.A1 grade glass fiber and OFNR (Optical Fiber Non-conductive Riser) rated yellow jacket, this cable meets fire safety requirements while providing excellent crush and bend resistance. The 1.8mm outer diameter enables efficient routing through existing infrastructure. TAA compliant certification and RoHS/ELV directive compliance make it ideal for government and enterprise procurement. **Ideal Applications:** Perfect for campus network backbone connections, data center interconnects, long-distance building-to-building links, and any installation requiring extended singlemode reach. The duplex configuration supports simultaneous bidirectional transmission. **Ordering & Support:** Available with custom lengths for specific requirements. Ships from multiple US locations with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty. Whether you need standard 80m or custom configurations, this TAA-compliant cable delivers enterprise-grade reliability.
