The JBX43622 fiber patch cable represents a reliable solution for demanding telecommunications and data center environments. This 55-meter simplex cable connects FC/APC connectors to ST/UPC connectors, accommodating diverse network equipment configurations commonly found in enterprise settings. **Technical Excellence:** Built with 9/125 singlemode fiber and G.657.A1 glass composition, this cable delivers outstanding optical performance. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure minimal signal loss across telecommunications wavelengths. The low insertion loss (≤0.35dB typical 0.15dB) and robust return loss (≥20dB) meet ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing reliability in critical applications. **Robust Construction:** The 1.8mm outside diameter provides a balance between durability and flexibility, while the OFNR riser-rated yellow jacket offers flame resistance suitable for vertical cable runs in buildings. The simplex design (single fiber strand) minimizes footprint while supporting point-to-point signal transmission. **Compliance & Standards:** TAA compliant and RoHS/ELV certified, this cable meets government procurement and environmental requirements. Manufactured in Taiwan, the US, or China, it maintains consistent quality across production facilities. **Practical Advantages:** Available in custom lengths for exact installation requirements, this cable eliminates waste and simplifies deployment. The 90-day limited warranty provides peace of mind, while free standard shipping on orders exceeding $99 reduces procurement costs. **Ideal Applications:** Perfect for connecting FC/APC equipped equipment to ST/UPC interfaces in telecommunications closets, data centers, laboratory testing setups, and enterprise network installations where singlemode performance and connector compatibility are critical. Choose the JBX43622 for dependable, standards-compliant fiber connectivity.
