The JBX85072 7-meter LC/ST duplex singlemode fiber patch cable represents professional-grade connectivity for demanding telecommunications, data center, and enterprise network applications. This cable is specifically engineered to transmit fiber signals with exceptional clarity and reliability over moderate distances. **Technical Excellence:** Crafted with 9/125 singlemode core and premium G.657.A1 glass fiber, this cable provides optimal performance for long-distance data transmission. The G.657.A1 specification ensures compatibility with standard singlemode fiber while offering bend-insensitive characteristics for easier installation in tight spaces. Insertion loss specifications of ≤0.35dB (0.15dB typical) and return loss ≥20dB exceed ANSI/TIA/EIA standards, ensuring signal integrity across both 1310 nm and 1550 nm wavelengths. **Identification and Safety:** The distinctive yellow outer jacket serves dual purposes: rapid cable identification in complex network environments and compliance with OFNR (Optical Fiber Non-conductive Riser) fire ratings. This means the cable is suitable for installation in vertical runs within buildings without conduit protection. **Connector Configuration:** LC/UPC to ST/UPC connectors with Type A to B crossover polarity provide the industry-standard connection architecture. This duplex configuration enables simultaneous bidirectional communication, essential for full-duplex network protocols. **Compliance and Reliability:** Fully RoHS and EU directive 2002/95/EC compliant, this cable meets stringent environmental and safety requirements. Includes 90-day limited warranty and is available in custom lengths for specialized installations. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders over $99. **Ideal Applications:** - Data center connectivity - Telecommunications networks - Campus network backbone - LAN/WAN installations - Broadcasting and video transmission **Storage and Maintenance:** Store in cool, dry conditions away from direct sunlight. Avoid sharp bends exceeding the cable's bend radius during installation. Regular inspection ensures continued optimal performance.
