The JBX43306 4-meter SC/APC to FC/UPC simplex singlemode fiber patch cable represents a versatile solution for telecommunications infrastructure, data center connectivity, and enterprise network installations requiring precision optical signal transmission. TECHNICAL SPECIFICATIONS: This cable features a 9/125 singlemode fiber core manufactured to G.657.A1 specifications, ensuring excellent bend radius performance while maintaining signal fidelity. The SC/APC (Angled Physical Contact) to FC/UPC (Ultra Physical Contact) connector configuration provides low back-reflection characteristics ideal for long-distance transmission. Measured insertion loss of ≤0.35dB (typical 0.15dB) at both 1310nm and 1550nm wavelengths demonstrates exceptional performance across telecommunications bands. Return loss exceeding 20dB minimizes signal degradation and crosstalk interference. DURASLE CONSTRUCTION: The 1.8mm outside diameter cable jacket features OFNR (Optical Fiber Non-Conductive Riser) rating, providing fire resistance suitable for in-building vertical and horizontal routing. The bright yellow jacket facilitates easy identification and tracing in complex installation environments. RoHS and ELV directive compliance ensures environmental responsibility and regulatory adherence. COMPLIANCE & CERTIFICATION: TAA (Trade Agreements Act) compliance makes this cable suitable for government and institutional procurement. All performance metrics conform to ANSI/TIA/EIA-455-171-A-2001 standards, ensuring compatibility with industry-standard testing and installation practices. FLEXIBLE OPTIONS: While this product ships in 4-meter lengths, custom lengths are available to accommodate specific installation requirements, reducing waste and installation complexity. The 90-day limited warranty provides peace of mind on your investment. APPLICATIONS: Ideal for carrier-grade telecommunications networks, enterprise LAN/WAN deployments, military installations, laboratory test environments, and any application requiring reliable singlemode optical connectivity. The simplex configuration supports unidirectional signal transmission, making it perfect for dedicated send or receive fiber runs in duplex systems.
