The JBX42382 SC/APC to ST/UPC duplex singlemode fiber patch cable represents a premium solution for organizations requiring reliable, standards-compliant fiber connectivity. At 55 meters in length, this cable accommodates larger facility deployments while maintaining the precision needed for sensitive optical communications. **Technical Excellence:** This duplex patch cable utilizes 9/125 singlemode fiber with G.657.A1 glass composition, delivering performance characteristics suitable for long-distance, high-bandwidth applications. The SC/APC (angled physical contact) connector on one end minimizes back-reflection, while the ST/UPC (straight physical contact) connector provides versatile compatibility with existing network infrastructure. Insertion loss specifications of ≤0.35dB (0.15dB typical) and return loss ≥20dB ensure signal integrity across extended runs, with attenuation measured at 0.25 dB/km (1310nm) or 0.35 dB/km (1550nm) per ANSI/TIA standards. **Durability and Compliance:** The yellow OFNR-rated (riser) jacket provides flame resistance and protection in building vertical runs while offering excellent visibility for technicians. At 1.8mm outside diameter, the compact design fits standard conduit and cable management systems. Full RoHS/ELV compliance and TAA certification make this cable ideal for government contracts, educational institutions, and enterprises subject to federal procurement requirements. **Practical Applications:** Ideal for data center interconnects, telecommunications networks, fiber-to-the-desktop installations, and disaster recovery setups. The Type A to B crossover configuration supports standard duplex patching scenarios without requiring additional adapters. **Flexible Sourcing and Support:** Custom lengths are available for specialized installations. Free standard shipping applies to orders exceeding $99, with fulfillment from three US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery. Every cable includes a 90-day limited warranty, backed by manufacturer testing protocols. Whether upgrading legacy systems or deploying new infrastructure, the JBX42382 delivers professional-grade reliability with government-approved credentials.
