The JBX88311 1m ST/ST Duplex Singlemode Fiber Patch Cable represents the gold standard in optical connectivity solutions for telecommunications professionals, network administrators, and data center engineers. This carefully engineered component delivers the performance and reliability required for mission-critical fiber optic networks. **Superior Optical Performance** Features a 9/125 singlemode core with advanced G.657.A1 glass composition, optimized for long-distance, high-speed signal transmission. Insertion loss testing confirms exceptional performance at ≤0.35dB (typical 0.15dB), while return loss exceeds 20dB—exceeding industry standards for signal integrity and minimizing signal degradation over extended runs. **Professional-Grade Construction** The duplex configuration provides simultaneous bidirectional communication with Type A to B crossover polarity, the industry-standard wiring for duplex patch cords. The compact 1.8mm outside diameter enables efficient cable management and routing through tight spaces, while OFNR riser-rated jacketing ensures compliance with building codes and fire safety standards. **Compliance & Quality Assurance** Fully TAA compliant for government and enterprise procurement. Manufactured to rigorous standards with attenuation specifications of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, verified against ANSI/TIA/EIA-455-171-A-2001 testing protocols. RoHS/ELV compliant construction reflects commitment to environmental responsibility. **Practical Deployment Benefits** With a 1-meter length, this cable is ideal for interconnecting network equipment, patch panels, and optical terminals. Multiple US warehouse locations (California, Texas, South Carolina) ensure rapid shipping with free standard delivery on orders over $99. Custom lengths are available for specialized installations. **Warranty & Support** Backed by a comprehensive 90-day limited warranty, providing peace of mind for critical installations. Whether upgrading existing infrastructure or designing new networks, this cable delivers dependable performance in telecommunications, data centers, and enterprise environments. **Applications** Perfect for LAN backbone connections, telecommunications infrastructure, FTTH installations, and any application requiring high-reliability singlemode fiber connectivity with minimal signal loss.
