The JBX43388 SC/APC to ST/UPC Simplex Singlemode Fiber Patch Cable represents professional-grade connectivity for modern optical networks. This 85-meter cable is specifically engineered to meet the stringent requirements of telecommunications infrastructure, data center operations, and enterprise network deployments. **Technical Excellence:** Built on a 9/125 singlemode fiber core with G.657.A1 glass composition, this cable delivers industry-leading performance metrics. The insertion loss specification of ≤0.35dB (with typical performance at 0.15dB) ensures minimal signal loss, while the return loss of ≥20dB provides exceptional signal integrity. Attenuation ratings of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm make this cable suitable for both traditional and modern wavelength applications. **Connector Configuration:** The SC/APC to ST/UPC pairing accommodates mixed-connector network environments, making this cable invaluable for legacy system integration and multi-vendor network architectures. The APC (Angled Physical Contact) end minimizes back-reflection, while the UPC (Ultra Physical Contact) standard end provides broad compatibility. **Installation & Safety:** Designed with OFNR (Optical Fiber, Non-Conductive, Riser rated) jacketing, this cable meets stringent fire codes for indoor installations without conduit. The 1.8mm outer diameter provides excellent flexibility for routing through cable trays, conduits, and tight spaces while maintaining structural integrity. The distinctive yellow color coding ensures rapid identification in complex network environments. **Compliance & Certification:** TAA (Trade Agreements Act) compliant, this cable meets government procurement standards. RoHS and ELV directives confirm environmental compliance and safe manufacturing practices. Attenuation testing adheres to ANSI/TIA/EIA-455-171-A standards, ensuring measured performance data. **Applications:** Ideal for telecommunications backbone connections, data center uplinks, fiber-to-the-premises (FTTP) installations, and long-distance signal transmission requiring high reliability and low signal loss. **Warranty & Support:** Backed by a 90-day limited warranty with quick shipment from multiple US locations. Custom lengths available for specialized network requirements. Free standard shipping on orders over $99.
