The JBX88310 is a premium 0.5-meter ST/ST duplex singlemode fiber patch cable engineered for mission-critical network applications. This optical accessory combines industry-leading performance with comprehensive compliance certifications, making it the ideal choice for government, enterprise, and data center environments. **Technical Excellence:** Features a precision 9/125 singlemode core with G.657.A1 glass fiber construction, supporting both 1310nm and 1550nm wavelengths. With insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB, this cable ensures minimal signal degradation and maximum data integrity. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm exceed industry standards. **Safety & Compliance:** TAA (Trade Agreement Act) compliant and fully RoHS/ELV certified per EU directive 2002/95/EC, ensuring it meets government procurement requirements. OFNR riser-rated jacketing (1.8mm OD) allows safe installation in building plenums without conduit, reducing installation costs and complexity. **Professional Construction:** Type A to B crossover polarity with ST/UPC connectors provides standard duplex configuration. Precision-molded connectors and reinforced strain relief ensure durability in high-traffic network installations. Custom lengths available for specialized applications. **Convenient Shipping:** Ships quickly from multiple U.S. facilities (Danville CA, Fort Worth TX, or Beaufort SC) with free standard shipping on orders over $99. Backed by a 90-day limited warranty. **Applications:** Perfect for connecting network switches, routers, servers, and fiber optic panels in data centers, telecommunications facilities, and enterprise networks. The short 0.5-meter length is ideal for equipment racks and densely populated patch panels.
