The JBX43052 55-meter LC/APC to LC/APC simplex singlemode fiber patch cable represents professional-grade connectivity for demanding optical network applications. Built to exacting telecommunications standards, this cable delivers exceptional performance for long-distance signal transmission in data centers, telecommunications facilities, and enterprise networks. **Key Technical Specifications:** Featuring a 9/125 micrometer singlemode fiber core with G.657.A1 bend-insensitive technology, this cable maintains signal integrity even in tight routing environments. The measured insertion loss of 0.15dB typical (≤0.35dB maximum) at 1310nm and 0.35dB/km at 1550nm ensures minimal signal degradation. Return loss exceeds 20dB, providing excellent signal reflectance characteristics critical for sensitive optical applications. **Design & Durability:** The cable's 1.8mm outer diameter with yellow OFNR-rated jacket combines visibility with safety compliance. The riser rating ensures proper fire safety classification for building installations. APC (Angled Physical Contact) connectors provide superior return loss performance compared to UPC alternatives, reducing back-reflections that can degrade signal quality. **TAA Compliance & Certifications:** Fully compliant with TAA (Trade Agreements Act) requirements, RoHS/ELV directives, and ANSI/TIA/EIA standards, this cable meets government procurement specifications. Manufacturing locations across Taiwan, US, and China ensure supply chain reliability and availability. **Flexibility & Customization:** While this product ships in the standard 55-meter length, custom lengths are available to suit specific installation requirements. Ships from multiple US locations (Danville CA, Fort Worth TX, and Beaufort SC) with free standard shipping on orders exceeding $99. **Applications:** Ideal for backbone connections, inter-building links, long-distance spans within data centers, and telecommunications infrastructure where single-strand simplex transmission is required. Perfect for connecting optical networking equipment, servers, and telecommunications hardware.
