The JBX93045 20-meter LC/SC duplex singlemode fiber patch cable represents a premium solution for professional fiber optic network installations. Engineered with precision and built to exacting standards, this cable combines reliability with performance for both new deployments and system upgrades. **Technical Excellence:** Constructed with a 9/125 singlemode core and G.657.A1 glass fiber, this cable provides superior signal transmission characteristics. The measured insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB ensure minimal signal degradation across standard operating wavelengths (1310nm and 1550nm). These specifications comply with ANSI/TIA/EIA-455-171-A-2001 testing standards, guaranteeing consistent performance. **Superior Protection and Compliance:** The orange OFNR (Optical Fiber Non-conductive Riser) rated jacket provides flame resistance, smoke control, and mechanical protection suitable for in-building cable runs. TAA (Trade Agreements Act) compliance makes this cable ideal for government, education, and institutional procurement requirements. RoHS/ELV directives ensure environmental responsibility without compromising performance. **Practical Design Features:** The duplex configuration with LC/UPC and SC/UPC connectors (Type A to B crossover) accommodates standard duplex patching scenarios common in modern data centers and telecommunications facilities. The compact 1.8mm outer diameter maximizes rack space efficiency while maintaining structural integrity. Available in custom lengths to match your specific infrastructure requirements. **Versatile Applications:** Ideal for backbone cabling, equipment interconnects, and patch panel applications in enterprise networks, ISP facilities, and telecommunications infrastructure. The 20-meter standard length bridges distances between equipment with minimal loss. **Quality Assurance:** Backed by a 90-day limited warranty and shipped from strategically located warehouses in California, Texas, and South Carolina, this cable combines convenience with reliability. Free standard shipping on orders over $99 reduces procurement costs for network integrators and system builders. Whether upgrading legacy systems or building new high-capacity networks, the JBX93045 delivers the performance, compliance, and durability required for professional installations.
