The JBX43796 4-meter SC/APC to E2000/APC simplex singlemode fiber patch cable represents a premium solution for professional fiber optic networks. This cable is engineered to meet the stringent requirements of telecommunications, data centers, and enterprise networking installations. **Optical Performance** Built with 9/125 micron singlemode core fiber, this cable delivers exceptional signal fidelity with insertion loss rated at ≤0.35dB (0.15dB typical) and return loss exceeding 20dB. Testing confirms compliance with ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent performance at both 1310nm and 1550nm wavelengths. The attenuation specification of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm meets carrier-grade requirements. **Construction & Features** The cable features a durable 1.8mm outside diameter with OFNR (Optical Fiber Non-conductive Riser) rated jacketing, making it suitable for vertical runs within buildings while maintaining fire safety standards. The bright yellow jacket facilitates quick identification and cable management in complex installations. SC/APC connectors provide industry-standard 8-degree angle polish contacts, while E2000/APC connectors offer enhanced shutter protection and alignment precision. **Compliance & Certification** This cable meets TAA (Trade Agreements Act) compliance requirements for federal government procurement. RoHS/ELV certification ensures environmental compliance across EU directives 2002/95/EC. The G.657.A1 grade fiber offers excellent bend radius performance, improving installation flexibility. **Applications** Ideal for data center interconnects, telecommunications infrastructure, campus backbone runs, and enterprise fiber networks. The simplex configuration suits point-to-point signal transmission applications. Custom lengths available for specific installation requirements. **Warranty & Support** Backed by a comprehensive 90-day limited warranty.
