The JBX42381 fiber patch cable represents a professional-grade solution for organizations requiring reliable single-mode fiber connectivity. At 50 meters in length, this duplex configuration provides substantial reach for data center interconnections, campus network expansions, and telecommunications infrastructure upgrades. **Technical Excellence** This singlemode patch cable utilizes a precision 9/125 micron core designed specifically for long-distance signal transmission. The G.657.A1 glass fiber meets international standards for bend-insensitive performance, reducing signal degradation in tight installation environments. With insertion loss specifications of ≤0.35dB and typical performance of just 0.15dB, the cable minimizes signal attenuation across the network span. **Superior Connector Performance** The SC/APC to ST/UPC connector configuration represents a Type A to B crossover arrangement—the industry standard for duplex patch cord applications. This configuration ensures proper polarity alignment and maximum signal integrity. SC/APC connectors feature angled physical contact for enhanced return loss (≥20dB), critical for high-performance fiber systems. **Professional Installation Features** The bright yellow riser-rated (OFNR) jacket provides exceptional visibility during installation and maintenance, reducing setup errors and troubleshooting time. At 1.8mm outside diameter, the cable navigates tight cable trays and conduit runs without compromising durability. Flexible routing capabilities make this patch cable suitable for both fixed installations and temporary network configurations. **Compliance & Sustainability** TAA compliance ensures this product meets government and institutional procurement standards. RoHS/ELV certification demonstrates commitment to environmental responsibility without compromising performance. The 90-day limited warranty provides confidence in product reliability. **Wavelength Versatility** Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure compatibility with diverse optical systems. This dual-wavelength capability supports both legacy and next-generation fiber optic infrastructure. **Custom Solutions Available** While this product ships as a standard 50-meter cable, custom lengths are available for specialized applications. Multiple US shipping locations enable rapid delivery to data centers, telecom facilities, and enterprise network environments. Free standard shipping on orders exceeding $99 reduces total cost of deployment. Ideal applications include data center interconnects, campus network backbone installations, telecommunications equipment connections, and high-speed network upgrades requiring reliable single-mode fiber performance.
