The JBX43382 SC/APC to ST/UPC simplex singlemode fiber patch cable is engineered for demanding telecommunications and data center applications requiring reliable, high-speed optical signal transmission. This 55-meter cable combines SC/APC (angled physical contact) and ST/UPC (straight tip/ultra-physical contact) connectors in a simplex configuration, making it ideal for unidirectional fiber optic connections in professional network infrastructure. Technical Excellence: This cable utilizes 9/125 micrometer singlemode fiber with G.657.A1 specification, supporting wavelengths at both 1310nm and 1550nm with minimal attenuation (0.25dB/km at 1310nm, 0.35dB/km at 1550nm). The measured insertion loss of ≤0.35dB and return loss of ≥20dB demonstrate superior optical performance, ensuring signal clarity and minimal data loss over extended distances. These specifications meet or exceed ANSI/TIA/EIA standards, providing confidence in mission-critical applications. Compliace & Durability: As a TAA-compliant product manufactured in Taiwan, the United States, or China, this cable meets federal procurement requirements. RoHS/ELV directive compliance (EU 2002/95/EC) ensures environmental responsibility. The OFNR (Optical Fiber Non-Conductive Riser) rated jacketing provides fire safety for vertical cable runs in building risers, while the 1.8mm diameter offers excellent flexibility for installation in existing cable pathways and conduits. Flexibility & Support: Custom length availability accommodates specific installation requirements beyond the standard 55-meter configuration. The 90-day limited warranty and responsive customer support ensure peace of mind. Free standard shipping on orders over $99 provides excellent value for network integrators, telecommunications professionals, and enterprise IT departments. Applications: Ideal for telecommunications networks, data center interconnects, campus network infrastructure, and scientific research facilities requiring robust optical fiber connectivity. The SC/APC-to-ST/UPC configuration bridges different connector standards common in legacy and modern network deployments, making this cable an essential solution for network upgrades and integration projects.
