The JBX93043 LC/SC Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity for mission-critical network infrastructure. This 12-meter patch cable combines precision engineering with proven reliability, making it an essential component for telecommunications facilities, data centers, and enterprise network environments. **Technical Excellence:** Constructed with a 9/125 micron singlemode core and G.657.A1 glass fiber, this cable delivers superior light transmission characteristics. The measured insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB meet stringent telecommunications standards. Attenuation specifications are verified at both 1310nm and 1550nm wavelengths (0.25dB/km and 0.35dB/km respectively), ensuring optimal performance across diverse network implementations. **Compliance and Safety:** As a TAA-compliant product meeting EU directive 2002/95/EC (RoHS/ELV), this cable satisfies government procurement requirements and environmental regulations. The OFNR riser-rated jacketing provides fire safety certification for vertical installations in building infrastructure, while the 1.8mm outside diameter allows flexible routing through cable management systems. **Practical Design Features:** The Type A to B crossover polarity configuration is the industry standard for duplex patch cords, eliminating compatibility concerns. Vibrant orange jacket color aids visual identification and asset management in complex network environments. The compact packaging supports efficient shipping and storage. **Versatile Applications:** Ideal for connecting telecommunications equipment, network switches, patch panels, and fiber distribution frames. Perfect for both new installations and upgrade projects in data centers, telecom facilities, and enterprise networks. Custom lengths available to meet specific deployment requirements. **Quality Assurance:** Every cable undergoes attenuation testing in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. The 90-day limited warranty provides peace of mind for critical infrastructure investments. Manufactured in Taiwan, US, or China locations ensures supply chain reliability. **Shipping and Support:** Qualifies for free standard shipping on orders exceeding $99. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) for expedited delivery. Professional customer support available to answer technical questions and assist with custom configurations.
