The JBX93179 90-Meter SC/SC Duplex Singlemode Fiber Patch Cable represents professional-grade optical connectivity designed for mission-critical network infrastructure. This comprehensive solution combines exceptional performance with regulatory compliance, making it ideal for federal projects, secure government facilities, and enterprise-level telecommunications systems. **Technical Excellence:** Constructed with 9/125 singlemode fiber core and G.657.A1 glass specifications, this cable delivers industry-leading performance metrics. The insertion loss rating of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while the return loss of ≥20dB maintains signal integrity across extended distances. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm meet or exceed ANSI/TIA/EIA-455-171-A-2001 standards. **Compliance & Quality:** Fully TAA compliant, this cable meets Buy American requirements for government procurement. RoHS and EU Directive 2002/95/EC certification ensures environmental responsibility. The OFNR (Optical Fiber, Non-conductive, Riser-rated) jacket provides essential flame protection for in-building vertical runs. **Design Features:** The SC/UPC to SC/UPC duplex configuration with Type A to B crossover polarity enables simultaneous bidirectional transmission, eliminating the need for separate transmit and receive cables. The 1.8mm outside diameter provides flexible routing through tight conduit spaces, while the orange jacket aids easy identification and organization in complex installations. **Application Scenarios:** Ideal for data centers upgrading to singlemode infrastructure, telecommunications facilities requiring long-distance signal transmission, government and military communications networks, and enterprise campuses connecting distant buildings. The 90-meter length accommodates substantial backbone runs without intermediate amplification. **Warranty & Support:** Backed by a comprehensive 90-day limited warranty. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Custom lengths available to meet specific installation requirements.
