The JBX42677 30m FC/APC to LC/UPC duplex singlemode fiber patch cable represents a mission-critical solution for telecommunications professionals, data center operators, and network infrastructure specialists requiring reliable, high-performance fiber connectivity. Technical Excellence: This cable features a 9/125 singlemode core designed for single-wavelength transmission across long distances with minimal signal degradation. The G.657.A1 bend-insensitive glass fiber technology reduces macro-bending loss, enabling deployment in space-constrained environments without compromising performance. Attenuation specs of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensure optimal performance across telecommunications windows. The duplex configuration (two fiber strands) enables bidirectional communication within a single cable assembly. Connector Performance: FC/APC (ferrule composite/angled physical contact) connectors on the transmit end provide ultra-low back-reflection, essential for analog and RF applications. LC/UPC (lucent connector/ultra-polished contact) receivers offer compact form factor ideal for high-density patch panels. The Type A to B crossover configuration is industry-standard for duplex cords, eliminating guesswork during installation. Compliance & Reliability: TAA (Trade Agreements Act) compliant for government procurement. RoHS/ELV certification ensures environmental responsibility. OFNR (optical fiber non-conductive riser) jacketing permits vertical runs between floors while maintaining fire safety standards. The 90-day limited warranty provides peace-of-mind protection. Practical Advantages: Bright yellow jacket enables quick identification in complex cable bundles, reducing troubleshooting time. Available in custom lengths for applications requiring non-standard dimensions. Multiple domestic fulfillment centers (Danville CA, Fort Worth TX, Beaufort SC) ensure fast delivery. Tested to ANSI/TIA/EIA-455-171-A standards for verified performance. Applications: Ideal for campus network interconnects, carrier-class telecommunications, medical imaging systems, broadcast facilities, and long-distance LAN backbones where singlemode fiber's extended range and minimal dispersion are essential.
