The JBX42197 30-meter LC/APC to FC/UPC duplex singlemode fiber patch cable represents the gold standard in optical connectivity for professional networking environments. This precision-engineered cable combines advanced fiber optic technology with enterprise-grade construction to deliver uncompromising performance in critical telecommunications infrastructure. **Technical Excellence** Features a 9/125 singlemode fiber core with G.657.A1 glass fiber specification, enabling low-loss signal transmission across extended distances. Testing performed in accordance with ANSI/TIA/EIA-455-171-A-2001 standards confirms insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB. Attenuation performance of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensures optimal signal quality for diverse wavelength applications. **Connector Specifications** The duplex configuration features LC/APC connectors on one end and FC/UPC connectors on the other, with Type A to B crossover polarity—the industry standard for duplex patch cords. This combination provides flexible integration with mixed-connector network environments while maintaining superior optical performance. **Construction & Durability** Riser-rated OFNR jacketing (1.8mm outside diameter) provides flame resistance and building code compliance. The robust plastic construction withstands typical installation stresses while the yellow color ensures easy identification in busy telecommunications closets. Manufactured in Taiwan, the United States, or China, each unit undergoes rigorous quality control. **Compliance & Certification** TAA (Trade Agreements Act) compliant for government procurement and RoHS/ELV certified under EU directive 2002/95/EC, making it suitable for environmentally conscious organizations and federally-funded projects. Each cable includes a 90-day limited warranty. **Applications** Ideal for data center interconnects, telecommunications closets, carrier networks, and enterprise fiber infrastructure requiring premium signal integrity. The 30-meter length accommodates typical building-scale distances while maintaining performance specifications. **Custom Solutions** Available in custom lengths to meet specific installation requirements.
