The JBX90203 SC/ST duplex singlemode fiber patch cable represents a professional-grade networking solution designed for demanding enterprise and telecommunications environments. This 60-meter cable combines precision engineering with compliance certifications required for government and mission-critical installations. **Superior Performance Specifications:** With a 9/125 micron singlemode core and G.657.A1 glass fiber construction, this cable achieves exceptional optical performance. The measured insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation across both 1310nm and 1550nm operating wavelengths. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm meet or exceed industry standards, making it suitable for long-distance data transmission. **Compliance & Reliability:** As a TAA-compliant product meeting EU directive 2002/95/EC (RoHS), this cable satisfies procurement requirements for government contracts and regulated industries. Rigorous attenuation testing follows ANSI/TIA/EIA-455-171-A standards, guaranteeing performance consistency and reliability. The 90-day limited warranty provides confidence in your network infrastructure investment. **Practical Design Features:** The distinctive pink jacket simplifies fiber identification in complex network installations, reducing configuration errors and maintenance time. The 1.8mm outer diameter allows flexible routing through tight spaces, while the OFNR riser-rated jacketing ensures fire safety compliance in building installations. Type A to B crossover polarity configuration enables standard duplex patch cord operations. **Flexible Solutions:** Custom lengths are available for applications requiring non-standard cable runs. The 60-meter length accommodates medium-distance backbone connections between equipment racks, telecommunications closets, and distribution points. Free standard shipping on orders exceeding $99 improves project economics. **Ideal Applications:** Perfect for data center interconnects, telecommunications facilities, enterprise LAN installations, fiber-to-the-desk deployments, and long-distance signal transmission requiring singlemode performance. The duplex configuration supports simultaneous bidirectional communication essential for modern network protocols.
