The JBX43454 FC/APC to FC/APC simplex singlemode fiber patch cable represents a reliable solution for professional-grade fiber optic networking applications. With its 2.5-meter length, this cable is ideal for interconnecting network equipment, telecommunications systems, and data center infrastructure where precise signal transmission is critical. **Key Technical Specifications:** This singlemode fiber patch cable features a 9/125 micron core with G.657.A1 glass composition, designed for operation at both 1310nm and 1550nm wavelengths. The cable delivers exceptional low attenuation at 0.25 dB/km (1310nm) or 0.35 dB/km (1550nm), ensuring minimal signal loss over distance. With insertion loss of ≤0.35dB and return loss of ≥20dB, it maintains signal integrity for demanding applications. **Professional Installation Features:** The FC/APC connectors provide angled physical contact, offering superior performance compared to standard FC/PC connections. The OFNR riser-rated jacketing makes this cable suitable for vertical runs in multi-story buildings while meeting fire safety codes. Its 1.8mm outer diameter provides excellent flexibility for routing through cable trays and conduits. **Compliance and Standards:** Fully TAA compliant and RoHS/ELV certified, this cable meets stringent government procurement requirements. Manufactured and tested according to ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality and performance. **Customization and Availability:** While the standard 2.5m length is readily available with free standard shipping on orders over $99, custom lengths are available upon request. Ships from multiple US locations (Danville CA, Fort Worth TX, and Beaufort SC) for faster delivery. **Applications:** Perfect for telecommunications infrastructure, DWDM systems, long-haul networks, data centers, and enterprise campus networks where single-direction transmission is required. The simplex configuration is ideal for dedicated transmission or reception paths. **Quality Assurance:** Backed by a 90-day limited warranty and manufactured to the highest standards across Taiwan, US, and China facilities, ensuring reliability and performance in mission-critical applications.
