The JBX42029 90-meter LC/APC to LC/UPC duplex single mode fiber patch cable represents a premium connectivity solution for mission-critical network infrastructure. Designed with precision engineering and manufactured to stringent quality standards, this cable delivers exceptional performance in telecommunications, data centers, and enterprise networking environments. **Technical Specifications:** This duplex cable features a 9/125 micron single mode fiber core, the industry standard for long-distance, high-speed data transmission. The LC/APC (Angled Physical Contact) to LC/UPC (Ultra Physical Contact) configuration ensures optimal signal integrity with crossover Type A to B polarity—the most common duplex patch cord configuration. Each fiber strand is individually optimized to achieve insertion loss of 0.15dB typical (maximum 0.35dB) and return loss exceeding 20dB, ensuring minimal signal degradation over the full 90-meter length. **Build Quality and Compliance:** Manufactured with G.657.A1 glass fiber and protected by an OFNR (Optical Fiber Non-conductive Riser) rated yellow jacket, this cable meets both safety and visibility requirements for building installations. The bright yellow color aids in identification and inventory management. All products are RoHS and ELV compliant, meeting EU directive 2002/95/EC. TAA compliance makes this cable suitable for government, institutional, and regulated enterprise purchases. **Performance Characteristics:** Optimized for both 1310nm and 1550nm wavelengths, the cable delivers consistent attenuation of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm. Performance is independently verified according to ANSI/TIA/EIA-455-171-A standards, ensuring reliability you can depend on. **Practical Applications:** • Data center interconnections and backbone cabling • Telecommunications network upgrades • Enterprise campus network deployments • High-speed internet service provider installations • Audio/visual production facilities with fiber requirements **Flexibility and Support:** While this listing features a 90-meter length, custom lengths are available upon request to match your exact installation requirements. With free standard shipping on orders over $99 and expedited options available, we ensure rapid deployment. A 90-day limited warranty provides peace of mind on your investment. Choose the JBX42029 for professional-grade fiber connectivity that combines performance, compliance, and reliability.
