The JBX90184 2.5m SC/ST duplex singlemode fiber patch cable represents a professional-grade solution for demanding telecommunications and network infrastructure applications. This meticulously engineered cable combines superior optical performance with compliance certifications required for government and enterprise deployments. **Key Technical Features:** Built on a 9/125 singlemode core with premium G.657.A1 glass fiber, this cable delivers exceptional attenuation characteristics: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. The duplex configuration with SC/UPC and ST/UPC connectors provides Type A to B crossover polarity—the most common configuration for patch cord applications. Insertion loss testing confirms performance of ≤0.35dB typical, while return loss exceeds 20dB, ensuring signal integrity for long-distance transmissions. **Compliance and Certifications:** TAA-compliant and certified to RoHS/ELV directives (EU 2002/95/EC), this cable meets procurement requirements for government agencies and regulated industries. Performance testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistency and reliability. **Design and Installation:** The compact 1.8mm outer diameter facilitates efficient cable management, while OFNR riser rating enables safe deployment in building risers and plenum spaces. The distinctive pink jacket simplifies identification in high-density cable environments, reducing installation errors and maintenance time. Custom lengths are available for specialized applications. **Applications:** Ideal for telecommunications facilities, data centers, enterprise networks, and carrier-grade deployments. Perfect for backbone connections, cross-connects, and repair patches where singlemode performance is essential. **Warranty and Support:** Includes 90-day limited warranty.
