The JBX43684 65-meter LC/UPC to FC/APC simplex singlemode fiber patch cable represents professional-grade connectivity for demanding network environments. This cable is engineered specifically for applications requiring reliable, high-speed data transmission over extended distances without signal degradation. Technical Specifications: This singlemode cable features a precision 9/125 micron core with G.657.A1 glass fiber, providing optimal performance across standard telecom wavelengths. The cable achieves exceptional attenuation characteristics: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. Insertion loss performance is ≤0.35dB with typical values of 0.15dB, while return loss exceeds 20dB—meeting or exceeding industry standards for data integrity. Connector Quality: Both LC/UPC and FC/APC connectors are precision-polished to ensure optimal coupling efficiency and minimal back-reflection. The simplex (single fiber strand) configuration supports unidirectional signal transmission, making it ideal for dedicated transmit or receive applications. Jacketing & Safety: The bright yellow OFNR (Optical Fiber Non-Conductive Riser-rated) jacket provides superior durability, flame resistance, and smoke suppression properties. At 1.8mm outside diameter, the cable maintains flexibility for routing through network cabinets and conduits. Compliance & Standards: TAA compliant for government and enterprise procurement requirements. Manufactured to ANSI/TIA/EIA-455-171-A standards with RoHS/ELV directive compliance. Includes a 90-day limited warranty. Applications: Ideal for telecommunications equipment interconnection, data center patch panels, test equipment connections, and DWDM systems. Custom lengths available for unique installation requirements. With multiple U.S. fulfillment centers and free standard shipping on orders over $99, this industrial-grade cable combines performance with convenience.
