The JBX43317 represents professional-grade connectivity for demanding fiber optic network applications. This 30-meter SC/APC to FC/UPC simplex singlemode patch cable combines precision engineering with proven reliability for telecommunications and data center environments. **Technical Excellence**: Built on G.657.A1 singlemode fiber specifications, the cable features a 9/125 core with 1.8mm outside diameter. Attenuation testing confirms performance at 1310 nm (0.25 dB/km) and 1550 nm (0.35 dB/km), with typical insertion loss of just 0.15dB and guaranteed maximum of 0.35dB. Return loss specification of ≥20dB ensures superior signal integrity for critical applications. **Connector Compatibility**: The SC/APC angled physical contact connector on one end interfaces with FC/UPC straight physical contact on the other, accommodating diverse network architectures. Straight-through polarity design enables straightforward installation without special adapters. **Professional-Grade Construction**: The riser-rated (OFNR) plastic jacket meets building safety codes for indoor installations, while the yellow color provides visual identification and organizational clarity in crowded server racks. Dimensions of 5.0" x 5.0" x 0.2" facilitate compact storage and deployment. **Compliance & Standards**: TAA-compliant certification ensures suitability for U.S. government and regulated entity procurement. RoHS/ELV compliance (EU Directive 2002/95/EC) demonstrates commitment to environmental responsibility. Manufactured in Taiwan, US, or China with rigorous quality assurance. **Value & Support**: Backed by a 90-day limited warranty and available in custom lengths for specialized applications. Free standard shipping applies to orders exceeding $99, with fulfillment from strategically located facilities (Danville CA, Fort Worth TX, or Beaufort SC) ensuring rapid delivery. **Ideal Applications**: Perfect for telecommunications infrastructure, data center connections, carrier-grade networks, and enterprise fiber deployments requiring reliable signal transmission over 30-meter distances. Widely adopted by IT professionals and network integrators for both new installations and system upgrades.
