The JBX43080 45-meter LC/APC to SC/UPC simplex singlemode fiber patch cable represents a professional-grade solution for telecommunications and networking applications requiring precise signal integrity and reliable connectivity. This cable is engineered to meet the demanding requirements of modern fiber optic networks while maintaining exceptional performance standards. **Technical Excellence:** Constructed with a 9/125 singlemode core and G.657.A1 glass fiber, this cable delivers outstanding optical performance. The insertion loss specification of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation. Attenuation measurements comply with ANSI/TIA/EIA-455-171-A-2001 standards, with performance tested at both 1310 nm (0.25 dB/km) and 1550 nm (0.35 dB/km) wavelengths. The straight-through polarity configuration provides straightforward installation. **Connector Advantages:** The LC/APC (Angle Physical Contact) connector offers superior return loss characteristics critical for sensitive applications, while the SC/UPC (Ultra Physical Contact) termination ensures broad compatibility across enterprise equipment. This combination provides flexibility for diverse networking environments. **Installation & Durability:** The OFNR (Optical Fiber, Non-conductive, Riser-rated) jacketing meets building codes for in-wall installations and plenum requirements. The 1.8mm outer diameter enables efficient cable management without excessive bulk. The bright yellow jacket facilitates easy identification and organization within complex cable systems. **Compliance & Certification:** Fully TAA (Trade Agreements Act) compliant for government procurement. RoHS/ELV directive certified ensures environmental responsibility. Available in custom lengths for specific installation requirements, providing flexibility for diverse network architectures. **Applications:** Ideal for telecommunications facilities, data centers, enterprise networks, fiber-to-the-desk installations, and backbone connections. Suitable for both new installations and network upgrades requiring high-performance single-strand fiber connectivity. **Warranty & Support:** 90-day limited warranty backs your investment.
