The JBX42484 ST/APC to ST/UPC duplex singlemode fiber patch cable represents the ideal solution for professional-grade fiber optic network infrastructure. This 2.5-meter cable combines precision engineering with practical design to deliver consistent, high-quality signal transmission in mission-critical applications. TECHNICAL SPECIFICATIONS: Constructed with 9/125 G.657.A1 singlemode fiber, this cable supports extended wavelength ranges with minimal attenuation. Testing confirms performance of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm wavelengths. The ≤0.35dB insertion loss (typical 0.15dB) ensures signal integrity, while ≥20dB return loss provides optimal performance in duplex configurations. Attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards. FEATURES & BENEFITS: The Type A to B crossover configuration is the industry-standard polarity for duplex patch cords, eliminating compatibility concerns. OFNR riser rating jacket material ensures code compliance for in-building installations, while the yellow color facilitates easy identification in dense cable runs. The 1.8mm outside diameter minimizes space requirements without compromising durability. COMPLIANCE & STANDARDS: TAA-compliant manufacturing ensures federal procurement eligibility. RoHS/ELV directive compliance confirms environmental responsibility. Manufacturing facilities in Taiwan, US, and China provide supply chain flexibility. APPLICATIONS: Ideal for data centers, telecommunications rooms, enterprise networks, and fiber-to-the-premises (FTTP) installations. The compact form factor suits both new installations and upgrades to existing infrastructure. SUPPORT & WARRANTY: 90-day limited warranty provides peace of mind. Available in custom lengths for specialized requirements. Free standard shipping on qualifying orders, with multiple fulfillment centers ensuring rapid delivery to continental US locations. MAINTENANCE TIP: Handle connectors with care to maintain performance. Keep dust caps on unused connectors and avoid exposing fiber ends to direct light sources or moisture.
