The JBX42468 45-meter FC/APC to FC/APC duplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network applications. Constructed with precision-engineered 9/125 singlemode fiber and G.657.A1 glass composition, this cable delivers the low-loss performance required for telecommunications, data centers, and long-distance signal transmission. Key Technical Features: This duplex configuration features two individually jacketed fiber strands, each 1.8mm in outside diameter, providing robust protection and flexibility for installation in tight spaces. The FC/APC (Angled Physical Contact) connectors offer superior return loss performance (≥20dB) compared to standard FC/PC connectors, reducing signal reflection and improving overall system performance. Tested according to ANSI/TIA/EIA-455-171-A standards, the cable achieves exceptional insertion loss specifications: ≤0.35dB maximum with typical performance of just 0.15dB per connection. Performance Across Wavelengths: The cable's attenuation characteristics are optimized for both C-band (1550nm at 0.35dB/km) and O-band (1310nm at 0.25dB/km) wavelengths, making it suitable for diverse telecommunications standards and applications. This dual-wavelength optimization ensures reliable performance regardless of your network's operating frequency. Compliance and Safety: Fully TAA compliant and RoHS/ELV certified per EU directive 2002/95/EC, this cable meets rigorous government procurement and environmental standards. The yellow OFNR (Optical Fiber Non-Conductive Riser) jacketing is fire-rated and suitable for installation in vertical building pathways and plenum-adjacent spaces, ensuring safety compliance in commercial installations. Flexibility and Customization: While this product is available in 45 meters, custom lengths are available to perfectly fit your installation requirements, reducing waste and simplifying deployment. Multiple U.S. warehouses in Danville CA, Fort Worth TX, and Beaufort SC ensure rapid order fulfillment with free standard shipping on orders exceeding $99. Perfect for telecommunications providers, data center operators, system integrators, and network professionals, this cable delivers the reliability and performance specifications required for demanding fiber optic networks. The Type A to B crossover polarity is standard for duplex applications and compatible with most network equipment. Invest in JBX42468 for dependable, low-loss signal transmission.
