The JBX42063 2-meter LC/APC to SC/UPC duplex singlemode fiber patch cable represents the gold standard in fiber optic connectivity solutions. Designed and tested to ANSI/TIA/EIA standards, this cable delivers reliable performance for mission-critical telecommunications and data center applications. **Technical Excellence:** This duplex patch cable features precision-engineered 9/125 singlemode fiber with advanced G.657.A1 glass composition, providing superior bend radius performance and minimal signal attenuation. The LC/APC connectors offer physical contact connections with industry-leading return loss of ≥20dB, while SC/UPC connectors ensure broad compatibility. With insertion loss of merely ≤0.35dB, this cable minimizes signal degradation across 1310nm and 1550nm wavelengths—critical for long-distance telecommunications. **Compliance & Safety:** TAA compliant and RoHS/ELV certified, this patch cable meets stringent government procurement and environmental standards. The OFNR riser-rated jacket provides superior fire safety when installed in vertical building runs, protecting critical infrastructure from fire hazards while maintaining network integrity. **Design & Practicality:** The Type A to B crossover polarity configuration (most common for duplex applications) eliminates confusion during installation. Distinctive yellow jacketing ensures quick visual identification in complex network environments. At just 1.8mm in diameter, the cable navigates tight conduit spaces with minimal footprint while maintaining robust durability. **Versatile Application:** Ideally suited for enterprise data centers, service provider networks, healthcare facilities, and financial institutions requiring dependable fiber connectivity. The 2-meter length accommodates standard patch panel configurations, with custom lengths available for specialized installations. **Service & Support:** Backed by a 90-day limited warranty and multiple US fulfillment locations (Danville CA, Fort Worth TX, Beaufort SC), ensuring rapid delivery.
