The JBX43277 is a premium-quality fiber optic patch cable engineered for demanding networking and telecommunications environments. At 5 meters in length, this simplex cable connects LC/APC connectors at one end to ST/APC connectors at the other, enabling flexible integration with diverse optical equipment and existing infrastructure. **Technical Excellence:** Built on a 9/125 singlemode fiber core with G.657.A1 classification, this cable delivers exceptional optical performance. Testing confirms insertion loss of ≤0.35dB (0.15dB typical) and return loss exceeding 20dB—specifications that exceed industry standards for high-fidelity signal transmission. The cable maintains consistent attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm, supporting both legacy and modern DWDM applications. **Professional Features:** The bright yellow OFNR-rated jacket (1.8mm OD) provides superior bend radius resistance and fire-safety compliance while enabling clear visual identification in cable management systems. APC (Angled Physical Contact) connectors minimize back-reflection and signal degradation—critical for maintaining data integrity across long distances. **Compliance & Certification:** Fully TAA compliant for U.S. federal and government purchases. RoHS/ELV certified to EU Directive 2002/95/EC. Manufactured to strict ANSI/TIA/EIA standards with rigorous attenuation testing. **Practical Applications:** Ideal for data centers, telecommunications closets, campus networks, and carrier-grade installations where signal quality cannot be compromised. The simplex design suits applications requiring unidirectional transmission, while custom length availability accommodates non-standard installations. **Convenient Logistics:** Qualifies for free standard shipping on orders exceeding $99 with strategic warehousing across multiple U.S. locations (California, Texas, South Carolina). 90-day limited warranty ensures customer confidence in this mission-critical component.
