The JBX43544 2.5m ST/APC to FC/UPC fiber patch cable represents professional-grade optical connectivity engineered for mission-critical applications. This simplex configuration features industry-standard 9/125 singlemode fiber with G.657.A1 glass specifications, delivering exceptional signal integrity across both 1310nm and 1550nm wavelengths. KEY TECHNICAL SPECIFICATIONS: Optical Performance: Attenuation is precisely tested to 0.25dB/km at 1310nm or 0.35dB/km at 1550nm, with typical insertion loss of just 0.15dB and return loss exceeding 20dB—well above industry standards. This ensures minimal signal degradation over distance, critical for long-haul telecommunications and sensitive instrumentation applications. CONSTRUCTION & DURABILITY: The 1.8mm outside diameter cable features durable plastic accessories and a riser-rated yellow jacket (OFNR), providing fire safety compliance and enhanced visibility in installation environments. Custom lengths available accommodate specific deployment requirements. COMPLIANCE & STANDARDS: TAA compliant for government and institutional procurement. RoHS/ELV certified per EU Directive 2002/95/EC. Manufacturing in Taiwan, USA, and China ensures quality consistency. All attenuation testing conducted per ANSI/TIA/EIA-455-171-A-2001 standards. APPLICATIONS: Ideal for data center interconnects, telecommunications infrastructure, campus network backbones, research laboratories, and telecommunications test equipment. The ST/APC and FC/UPC connector combination provides compatibility with diverse legacy and modern equipment. VALUE PROPOSITION: With free standard shipping on orders exceeding $99, 90-day limited warranty coverage, and availability from multiple distribution centers (Danville CA, Fort Worth TX, Beaufort SC), this cable delivers professional reliability at competitive pricing. Whether upgrading existing infrastructure or deploying new fiber networks, the JBX43544 provides the performance, compliance, and durability required for professional optical communications.
