The JBX42136 SC/APC to SC/UPC duplex single mode fiber patch cable represents a professional-grade solution for critical network connectivity needs. At 25 meters in length, this cable bridges intermediate distances in fiber optic networks while maintaining superior signal integrity. **Technical Excellence:** Constructed with a 9/125 single mode core and G.657.A1 glass fiber, this cable is optimized for long-distance, high-bandwidth telecommunications. The SC/APC to SC/UPC configuration provides Type A to B crossover polarity—the industry standard for duplex patch cords. Performance metrics include insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB, ensuring minimal signal degradation across 1310nm and 1550nm wavelengths. **Build Quality & Compliance:** The yellow OFNR (optical fiber non-conductive riser-rated) jacket offers flame resistance suitable for indoor building installations while providing high visibility for network management. The 1.8mm outside diameter balances durability with flexibility for routing through conduit systems. Full TAA compliance and RoHS/ELV certification make this cable ideal for government contracts and enterprises with strict procurement standards. **Versatile Applications:** Perfect for data center interconnects, telecommunications networks, university campuses, and enterprise backbone systems. The duplex design supports bidirectional communication, making it essential for network infrastructure requiring simultaneous transmission and reception. **Custom Options & Support:** While this product ships in 25m lengths, custom lengths are available to match specific installation requirements. Attenuation testing adheres to ANSI/TIA/EIA-455-171-A standards, guaranteeing reliability. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. **Warranty & Value:** Backed by a 90-day limited warranty, this cable represents a cost-effective investment in network infrastructure reliability. Proper storage and handling ensure optimal performance throughout its operational lifespan.
