The JBX43321 SC/APC to FC/UPC Simplex Fiber Patch Cable represents enterprise-level connectivity for demanding optical networking applications. This 50-meter cable combines precision engineering with practical performance specifications to meet the rigorous demands of telecommunications infrastructure, data centers, and high-speed networking environments. **Core Technical Specifications:** Constructed with 9/125 singlemode fiber complying with G.657.A1 standards, this cable supports both 1310nm and 1550nm wavelengths with exceptional low-loss characteristics. The insertion loss of ≤0.35dB ensures minimal signal degradation over the 50-meter run, while the ≥20dB return loss specification prevents reflections that could compromise signal quality. Tested rigorously against ANSI/TIA/EIA-455-171-A standards, this cable provides measurable, verified performance. **Design and Compliance:** The yellow OFNR (riser-rated) jacket provides both safety and visibility in installation environments. TAA compliance ensures this product meets federal procurement requirements for government and institutional buyers. RoHS and ELV directive compliance reflects modern environmental and safety standards. The 1.8mm outer diameter balances durability with space efficiency in cable trays and conduit systems. **Practical Applications:** Ideal for connecting telecommunications equipment, network switches, and optical distribution frames. The SC/APC to FC/UPC configuration accommodates diverse equipment requirements, eliminating the need for additional adapters. Suitable for campus networks, inter-building connections, and equipment interconnections requiring premium signal quality. **Customization and Support:** While this 50m configuration is ready to deploy, custom lengths are available upon request to match specific installation requirements. The cable ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery. Free standard shipping applies to orders exceeding $99. **Warranty and Reliability:** Backed by a 90-day limited warranty, the JBX43321 demonstrates manufacturer confidence in long-term reliability. Proper handling and storage extend cable lifespan significantly. The cable's construction supports both temporary test applications and permanent installations in controlled environments.
