The JBX43225 20-meter LC/APC to FC/APC simplex singlemode fiber patch cable represents a professional-grade solution for mission-critical fiber optic applications. Manufactured to rigorous standards with options available in Taiwan, US, and China facilities, this cable combines superior optical performance with practical installation features. **Optical Performance Specifications:** Built on G.657.A1 singlemode glass fiber with a precise 9/125 micron core geometry, the JBX43225 achieves exceptional attenuation characteristics tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. The insertion loss rating of ≤0.35dB (with typical performance of 0.15dB) ensures minimal signal degradation over the 20-meter span, while return loss of ≥20dB provides superior isolation and minimizes back-reflection interference. **Connector Technology:** The LC/APC to FC/APC configuration utilizes angled physical contact (APC) connector technology on both ends, reducing back-reflection and improving signal quality compared to standard connectors. LC (Lucent Connector) terminations provide compact, high-density connection capabilities, while FC (Fixed Connector) receptacles offer robust mechanical coupling ideal for stationary installations. **Installation & Compliance:** The OFNR (Optical Fiber Non-conductive Riser) rating ensures compliance with building fire codes for vertical installation in multi-story structures. At 1.8mm outside diameter with Riser-rated plastic jacketing, this cable integrates seamlessly into existing infrastructure without requiring conduit modifications. The distinctive yellow outer jacket facilitates quick visual identification in complex network topologies, reducing installation errors and maintenance time. TAA (Trade Agreements Act) compliance certifies this cable for U.S. government procurement and federal contracting requirements, making it essential for classified installations and government-regulated environments. **Application Areas:** - Telecommunications network backbone installations - Data center interconnect (DCI) systems - DWDM (Dense Wavelength Division Multiplexing) systems - Long-distance signal transmission - Enterprise network infrastructure upgrades - Government and military communications systems **Logistics & Support:** Available for immediate shipment from three U.S. distribution centers (Danville CA, Fort Worth TX, and Beaufort SC), with qualifying orders receiving free standard shipping. Custom lengths available for specialized requirements. Backed by a 90-day limited warranty and comprehensive technical support, ensuring peace of mind in critical applications.
