The JBX43790 SC/APC to E2000/APC Simplex 9/125 Singlemode Fiber Patch Cable is engineered for professionals requiring exceptional optical performance in critical telecommunications infrastructure. This 0.5m preconnectorized cable combines precision engineering with proven reliability, making it an ideal choice for data centers, telecommunications networks, and enterprise fiber installations. Key Technical Specifications: Built on a 9/125 singlemode fiber core with G.657.A1 glass composition, this cable supports both 1310nm and 1550nm wavelengths with superior attenuation characteristics (0.25 dB/km at 1310nm, 0.35 dB/km at 1550nm). The cable's insertion loss of ≤0.35dB (typically 0.15dB) and return loss of ≥20dB ensure minimal signal reflection and optimal data integrity. Design & Durability: The yellow OFNR-rated jacket provides both visual identification and fire-rated protection, with a compact 1.8mm outside diameter for easy routing through cable trays and conduit. TAA compliance and RoHS/ELV certification ensure adherence to government purchasing standards and environmental regulations. Perfection in Simplex Configuration: The simplex design features a single fiber strand, making it cost-effective for unidirectional communication applications while reducing installation complexity compared to duplex alternatives. Quality Assurance: Every cable is individually attenuation tested per ANSI/TIA/EIA-455-171-A standards, backed by a 90-day limited warranty. Multiple US fulfillment centers (Danville CA, Fort Worth TX, Beaufort SC) enable fast shipping with free standard delivery on orders exceeding $99. Customization Available: Beyond the standard 0.5m length, custom lengths are available to accommodate specific installation requirements. Whether upgrading existing infrastructure or building new networks, this cable delivers the performance professionals demand.
