The JBX42311 9-meter SC/APC to FC/UPC duplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network applications. Designed for organizations requiring dependable fiber optic infrastructure, this cable combines precision engineering with industry compliance to deliver superior performance in telecommunications and data center environments. **Superior Technical Performance:** Built with 9/125 singlemode fiber core and G.657.A1 glass fiber technology, the cable achieves exceptional low-loss characteristics. With insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB, signal integrity is maintained over extended distances. Attenuation specifications of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensure reliable performance across dual-wavelength systems commonly used in modern fiber networks. **Compliance and Safety:** TAA-compliant designation makes this cable suitable for government and regulated procurement. RoHS/ELV compliance ensures environmental responsibility, while OFNR riser-rating permits installation through building risers and air-handling spaces. Manufacturing to ANSI/TIA/EIA-455-171-A standards guarantees consistent quality and reliability. **Practical Design Benefits:** The compact 1.8mm outside diameter facilitates routing through congested cable trays and tight conduit runs. Type A to B crossover polarity configuration matches standard duplex patch cord applications, eliminating compatibility confusion. The distinctive yellow jacket aids visual identification and cable management organization. **Application Versatility:** Ideal for data center infrastructure, telecommunications facilities, DWDM systems, and high-speed network backbone connections. Custom lengths available for specialized installations. **Warranty and Support:** 90-day limited warranty provides peace of mind. Free standard shipping on orders over $99, with inventory available from multiple US locations ensuring quick delivery.
