The JBX42307 5-meter SC/APC to FC/UPC duplex singlemode fiber patch cable represents the ideal solution for telecommunications professionals and network engineers requiring certified, high-performance fiber connectivity. This duplex patch cable features two fiber strands operating simultaneously, enabling full-duplex communication across a single physical cable. Technical Excellence: Constructed with premium 9/125 singlemode glass fiber (G.657.A1 specification), this cable achieves exceptional optical performance. With insertion loss rated at ≤0.35dB (0.15dB typical) and return loss exceeding 20dB, the JBX42307 exceeds industry standards for signal fidelity. Attenuation specifications of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensure optimal performance across common telecommunications wavelengths. Compliance & Certification: TAA compliant for government and institutional procurement, this cable meets stringent regulatory requirements including RoHS/ELV directives (EU 2002/95/EC). Testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent quality and reliability. Physical Design: The bright yellow riser-rated (OFNR) jacket provides excellent visibility in dense patch panel environments while meeting indoor safety ratings. The 1.8mm compact diameter optimizes cable management and reduces bundle size in equipment racks. Type A to B crossover polarity configuration suits the most common duplex patch cord applications. Applications: Ideal for data centers, telecommunications facilities, carrier networks, and enterprise backbone connections requiring reliable single-mode fiber transmission. The 5-meter length accommodates typical equipment spacing while remaining cost-effective. Customization & Support: Custom lengths available for specialized requirements. Includes 90-day limited warranty. Ships from multiple U.S. locations with free standard shipping on orders exceeding $99. Professional-grade quality backed by comprehensive testing and certification.
