The JBX88288 ST/ST singlemode fiber patch cable represents professional-grade connectivity engineered for demanding telecommunications and data center applications. This 6-meter duplex cable delivers the reliability and performance required by enterprise network infrastructures. **Key Technical Features:** This cable utilizes a 9/125 singlemode core with G.657.A1 glass fiber, specifically optimized for long-distance, high-bandwidth signal transmission. Testing confirms insertion loss of ≤0.35dB at typical levels (0.15dB typical) and return loss exceeding 20dB, ensuring minimal signal degradation. The cable operates efficiently at both 1310 nm and 1550 nm wavelengths, with attenuation rates of 0.25 dB/km and 0.35 dB/km respectively. **Construction and Compliance:** The cable features a compact 1.8mm outside diameter wrapped in OFNR (Optical Fiber Nonconductive Riser) jacketing, meeting critical fire safety and environmental standards. It is fully RoHS and ELV compliant and carries TAA certification, making it ideal for government and regulated sector deployments. **Practical Applications:** Perfect for connecting network switches, routers, and storage devices in fiber-optic backbone installations, the ST/UPC connectors provide reliable Type A to B crossover connectivity typical of duplex patch cord configurations. The green jacket aids in cable identification within complex network installations. **Warranty and Support:** Backed by a 90-day limited warranty and available in custom lengths for specialized requirements. Ships from multiple U.S. locations for expedited delivery, with free standard shipping on orders exceeding $99. **Quality Assurance:** Manufactured to exacting standards and tested in accordance with ANSI/TIA/EIA-455-171-A-2001, ensuring consistent performance and reliability across all deployments.
