The JBX42580 ST/APC to FC/APC duplex singlemode fiber patch cable is engineered for demanding telecommunications and data center environments requiring precise optical signal transmission. Manufactured to exacting standards, this 8-meter cable features a robust 9/125 singlemode fiber core optimized for long-distance communication over extended wavelengths. Key Technical Features: This duplex cable incorporates G.657.A1 glass fiber with an ultra-low outside diameter of 1.8mm, enabling flexible routing in tight spaces without compromising performance. The Type A to B crossover polarity configuration is the industry standard for duplex patch cords, ensuring seamless integration with existing network infrastructure. Attenuation performance is tested to ANSI/TIA/EIA-455-171-A-2001 standards, delivering consistent 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm. Build Quality & Compliance: The protective plastic jacket is OFNR riser-rated, meeting fire safety codes for vertical installations within building structures. TAA compliance ensures the cable meets U.S. federal procurement requirements for government and institutional projects. RoHS and EU directive 2002/95/EC certification confirms environmental and health safety compliance across all markets. Practical Applications: Ideal for connecting fiber distribution panels to network equipment, backbone cabling, or long-distance signal transmission in enterprise environments. The distinctive yellow coloring facilitates quick identification during maintenance or troubleshooting, reducing downtime and configuration errors.
