The JBX88206 ST/ST duplex singlemode fiber patch cable represents professional-grade connectivity for demanding network environments. This 25-meter cable is engineered to deliver reliable fiber signal transmission with industry-leading performance specifications. **Technical Excellence:** With a 9/125 micron singlemode core and G.657.A1 glass fiber construction, this cable provides superior attenuation performance at both 1310nm (0.25 dB/km) and 1550nm (0.35 dB/km) wavelengths. The insertion loss specification of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation across long-distance telecommunications links. Testing conducted in accordance with ANSI/TIA/EIA-455-171-A-2001 standards guarantees consistent, reliable performance. **Compliance & Quality:** TAA compliant construction ensures this cable meets federal government purchasing requirements for commercial and institutional applications. RoHS/ELV directive compliance demonstrates environmental responsibility without compromising performance. The OFNR-rated yellow jacket provides both safety and visibility in professional installations. **Construction Details:** The duplex configuration features ST/UPC connectors in Type A to B crossover polarity (standard for duplex patch cords), facilitating seamless integration into existing infrastructure. The 1.8mm outside diameter accommodates standard fiber racks and cable management systems. Riser-rated jacketing permits installation in indoor spaces without conduit. **Practical Applications:** Ideally suited for data center interconnections, campus network backbones, telecommunications facilities, and any installation requiring 25-meter singlemode fiber connectivity. The yellow jacket aids in circuit identification and troubleshooting in complex multi-cable environments. **Customization Available:** Beyond the standard 25-meter length, custom cable lengths are available to meet specific installation requirements.
