The JBX43121 SC/APC to SC/UPC 1m Simplex Singlemode Fiber Patch Cable represents a premium solution for optical signal transmission in telecommunications, data centers, and network infrastructure projects. This professionally engineered cable combines performance, compliance, and reliability in a compact form factor. **Technical Specifications & Performance:** Built with a 9/125 singlemode fiber core and G.657.A1 glass specification, this cable operates efficiently across standard telecommunications wavelengths. The insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB exceed industry standards established by ANSI/TIA/EIA-455-171-A-2001. Attenuation characteristics measure 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, ensuring minimal signal degradation over the cable length. **Design & Construction:** The simplex configuration provides single-direction signal transmission, ideal for applications requiring unidirectional fiber paths. The distinctive yellow jacket aids in quick visual identification during installation and maintenance, while the riser-rated (OFNR) construction ensures compliance with building safety codes. The compact 1.8mm outer diameter facilitates easy routing through existing conduits and cable management systems. **Compliance & Standards:** This cable is fully TAA-compliant, meeting requirements for government and federal procurement. RoHS/ELV certification ensures environmental responsibility and regulatory compliance. Manufacturing facilities in Taiwan, US, and China provide supply chain flexibility and reliability. **Applications:** Ideal for connecting fiber network equipment, optical transceivers, and telecommunications infrastructure. Perfect for LANs, WANs, and carrier-grade deployments where signal integrity is paramount. **Custom Solutions:** While this 1m version suits standard installations, custom lengths are available for specialized projects. Standard free shipping applies to orders exceeding $99, with multiple fulfillment locations ensuring rapid delivery.
