The JBX88340 ST/ST singlemode fiber patch cable represents professional-grade connectivity engineered for mission-critical network applications. Measuring 0.5 meters in length, this duplex fiber cable combines precision engineering with proven reliability for telecommunications, data center, and enterprise network infrastructure. **Technical Specifications & Performance:** This cable features a 9/125 singlemode fiber core construction, the industry standard for long-distance, high-bandwidth telecommunications. The G.657.A1 glass fiber composition ensures superior light transmission characteristics with minimal chromatic dispersion. With insertion loss as low as 0.15dB typical (maximum 0.35dB) and return loss exceeding 20dB, this patch cable meets rigorous performance standards for professional installations. **Compliance & Standards:** Full TAA compliance ensures this product meets government procurement requirements. RoHS and ELV directive compliance (EU 2002/95/EC) reflects our commitment to environmental responsibility. All attenuation values are verified according to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent quality across every unit manufactured. **Connector Configuration:** The ST/UPC to ST/UPC connector pairing with Type A to B crossover polarity represents the most common duplex patch cord configuration, ensuring seamless integration with existing network infrastructure. The 1.8mm outer diameter allows flexible routing through cable management systems. **Construction & Durability:** OFNR riser-rated jacketing provides the safety certifications required for in-building deployment while protecting against physical damage and environmental stress. The 90-day limited warranty demonstrates manufacturer confidence in this product's durability and performance. **Applications:** Ideal for connecting switches, patch panels, and network equipment in data centers, telecommunications facilities, and enterprise network rooms. The 0.5-meter length makes it perfect for equipment-to-equipment connections in densely populated server racks where space optimization is critical. **Availability & Support:** Ship from multiple US locations (California, Texas, and South Carolina) ensures fast delivery. Custom lengths available for specialized requirements. Free standard shipping on orders exceeding $99 reduces total deployment costs for larger installations.
