The JBX42974 2.5m LC/UPC to LC/UPC Simplex Singlemode Fiber Patch Cable represents professional-grade connectivity infrastructure for organizations requiring reliable fiber optic transmission. This single-strand (simplex) cable configuration is engineered specifically for one-directional signal transmission, making it ideal for applications where unidirectional communication is required. **Technical Excellence:** Featuring 9/125 singlemode fiber with G.657.A1 glass composition, this cable delivers superior performance characteristics. With insertion loss of ≤0.35dB (typical 0.15dB) and return loss exceeding 20dB, signal integrity remains optimized across standard telecom wavelengths (1310nm and 1550nm). Testing conducted per ANSI/TIA/EIA-455-171-A standards ensures consistent quality and reliability. **Compliance & Safety:** TAA-compliant manufacturing ensures this cable meets U.S. government procurement requirements. The OFNR (Optical Fiber, Nonconductive, Riser Rated) jacket certification confirms fire safety and building code compliance. RoHS/ELV directive adherence demonstrates environmental responsibility without performance compromise. **Practical Benefits:** The distinctive yellow jacket provides quick visual identification in complex installations, reducing connection errors. At 1.8mm outside diameter, the cable maintains space efficiency while supporting robust signal transmission. Straight-through polarity ensures predictable performance in standard network configurations. **Flexibility & Support:** Available in custom lengths beyond the standard 2.5m specification, this cable adapts to unique installation requirements. The 90-day limited warranty provides confidence in product reliability. Free standard shipping on orders over $99, with fulfillment from multiple U.S. locations, ensures prompt delivery. **Ideal Applications:** Perfect for data center patch panel connections, campus fiber backbone links, and telecommunications infrastructure upgrades. The simplex configuration suits applications like video transmission, single-direction data links, or sensor connectivity where single-fiber operation is advantageous.
