The JBX42633 SC/APC to LC/UPC 2-meter duplex singlemode fiber patch cable is a high-specification optical connectivity solution designed for mission-critical network environments. This premium cable combines superior performance characteristics with compliance certifications required by government and enterprise procurement standards. **Technical Excellence:** Constructed with 9/125 singlemode fiber and G.657.A1 glass fiber technology, this cable delivers industry-leading performance metrics. The insertion loss specification of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while the return loss of ≥20dB meets stringent performance requirements. Attenuation testing in accordance with ANSI/TIA/EIA-455-171-A-2001 standards guarantees consistent quality across all wavelengths, with ratings of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm. **Durability and Safety:** The yellow outer jacket features OFNR (Optical Fiber Non-Conductive Riser) rated construction, meeting critical building safety codes for indoor installations. At 1.8mm outside diameter, the cable offers flexibility for routing through cable trays and conduit systems while maintaining structural integrity. RoHS/ELV compliance eliminates hazardous substances, supporting sustainable procurement practices. **Compliance and Certification:** TAA (Trade Agreements Act) compliance makes this cable eligible for government contracts and federal projects. Multi-region manufacturing (Taiwan, US, China) ensures supply chain resilience and availability. **Flexibility and Support:** While this cable comes standard at 2 meters, custom length options are available to meet specific installation requirements. Free standard shipping on orders over $99, with fulfillment from three strategically located distribution centers, ensures rapid delivery. The 90-day limited warranty provides peace-of-mind protection for your investment. **Ideal Applications:** Perfect for telecommunications infrastructure, enterprise data centers, fiber optic backbone installations, and FTTP deployments where performance and compliance cannot be compromised.
