The JBX42338 8-meter SC/APC to FC/APC duplex single mode fiber patch cable represents professional-grade connectivity for enterprise network environments. This cable is engineered to meet the stringent requirements of modern telecommunications infrastructure, delivering consistent performance in mission-critical applications. Key Technical Specifications: This duplex configuration features two individual fibers with 9/125 micrometer cores, each surrounded by a 250-micrometer cladding. The G.657.A1 fiber specification provides excellent bend performance while maintaining superior signal transmission characteristics. At 1310 nm, attenuation measures 0.25 dB/km; at 1550 nm, 0.35 dB/km—both well within industry standards. The insertion loss specification of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while return loss ≥20dB provides excellent signal reflection control. Connector Technology: The SC/APC to FC/APC configuration offers a Type A to B crossover arrangement, the most common polarity for duplex patch cords. The APC (Angled Physical Contact) angle-polished connectors minimize back reflection and provide superior performance compared to standard PC connectors, making them ideal for coherent systems and sensitive applications. Quality and Compliance: Testing follows ANSI/TIA/EIA-455-171-A-2001 standards, ensuring reproducible results and compatibility across installations. The cable carries TAA compliance certification, meeting government procurement requirements. RoHS and ELV directives compliance demonstrates environmental responsibility and regulatory adherence. The riser-rated (OFNR) PVC jacket meets fire code requirements for plenum-adjacent installations. Practical Advantages: The bright yellow jacket enables rapid cable identification in complex network environments, reducing installation and troubleshooting time. At 8 meters, this length accommodates typical rack-to-rack or equipment-to-patch-panel distances common in data centers and network facilities. The 1.8mm diameter provides flexibility for routing through conduit and cable management systems. Wide Manufacturing Support: Available from multiple U.S. manufacturing facilities and certified international partners, this cable ensures supply chain reliability. Custom lengths are available for specialized applications. The 90-day limited warranty provides confidence in product quality. Applications: Ideal for single mode fiber networks, long-distance telecommunications, data center interconnects, and any application requiring low-loss signal transmission. Perfect for DWDM systems, long-reach Ethernet, and specialized optical networks demanding minimal attenuation and superior return loss performance. This cable represents the intersection of performance, compliance, and reliability needed in professional fiber optic installations.
