The JBX43717 5-meter SC/APC to LC/UPC simplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network applications. Engineered with precision manufacturing standards, this optical cable bridges incompatible connector types while maintaining signal integrity essential for high-speed data transmission. **Technical Specifications:** This cable features a robust 9/125 micron singlemode core construction utilizing G.657.A1 glass fiber technology. The straightthrough polarity configuration ensures optimal signal alignment between SC/APC and LC/UPC connectors. With an outer diameter of just 1.8mm, the cable offers exceptional flexibility without compromising structural integrity. The yellow OFNR (Optical Fiber Non-conductive Riser-rated) jacket provides fire-resistant protection suitable for in-building vertical runs and plenum environments. **Performance Metrics:** Insertion loss performance is exceptional at ≤0.35dB with typical values of 0.15dB, exceeding industry standards. Return loss specification of ≥20dB ensures minimal signal reflection and crosstalk. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm support both traditional and extended wavelength applications. **Compliance & Standards:** Fully TAA compliant for U.S. government procurement, this cable meets EU RoHS/ELV directives (2002/95/EC). Manufacturing adheres to ANSI/TIA/EIA-455-171-A standards, guaranteeing consistent quality across batches. **Practical Applications:** Ideal for data centers, telecommunications facilities, ISP backbone connections, enterprise networks, and any installation requiring bridging between different connector types. The simplex design suits point-to-point transmission links where unidirectional communication is required. **Flexibility & Support:** Custom lengths are available for specialized installations.
