The JBX43393 represents a professional-quality fiber optic patch cable engineered for critical network infrastructure. This 2-meter simplex cable connects SC/APC to ST/APC connectors, providing a single-strand fiber solution for applications requiring unidirectional signal transmission or dedicated backup paths. **Technical Excellence** Constructed with 9/125 singlemode fiber core and G.657.A1 grade glass, this cable delivers exceptional performance characteristics. Attenuation testing confirms compliance with ANSI/TIA/EIA-455-171-A-2001 standards, with measured performance of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. The typical insertion loss of 0.15dB (maximum ≤0.35dB) and return loss exceeding 20dB ensure minimal signal degradation across telecommunications frequencies. **Build Quality & Compliance** The 1.8mm outside diameter yellow jacket features OFNR riser rating, making it suitable for vertical installations in building plenums without requiring conduit. TAA compliance and RoHS/ELV certification satisfy government procurement requirements and environmental regulations. Multiple manufacturing origins (Taiwan, US, China) ensure supply chain reliability. **Applications & Flexibility** Ideal for telecommunications facilities, data centers, fiber-to-the-premises (FTTP) installations, and network equipment testing. The straight-through polarity configuration supports standard bidirectional systems while the simplex design provides dedicated single-direction paths. Custom length options accommodate non-standard installation requirements. **Value & Support** Includes 90-day limited warranty and free standard shipping on orders exceeding $99. Ships from multiple US distribution centers for rapid delivery. Professional-grade construction ensures long-term reliability in mission-critical network environments.
