The JBX43637 5-meter ST/APC to LC/UPC simplex singlemode fiber patch cable represents professional-grade connectivity for modern fiber optic networks. This precision-engineered cable serves telecommunications companies, data centers, ISPs, and enterprise IT infrastructure requiring reliable, high-speed signal transmission. **Technical Specifications:** Built with 9/125 G.657.A1 singlemode fiber, this cable delivers industry-leading performance metrics. The insertion loss of ≤0.35dB (0.15dB typical) ensures minimal signal degradation over the 5-meter span, while return loss of ≥20dB maintains signal integrity critical for modern optical communications. Testing complies with ANSI/TIA/EIA-455-171-A standards, guaranteeing consistent performance. **Connector Design:** The ST/APC connector provides angled physical contact termination, ideal for reducing back reflection. The LC/UPC connector features ultra-polished finish for standard physical contact. This combination makes the cable suitable for diverse network architectures and existing infrastructure compatibility. **Installation & Benefits:** • Simplex configuration (single fiber strand) for dedicated unidirectional transmission • Yellow OFNR riser-rated jacket (1.8mm OD) rated for building plenum and riser installations • Straight-through polarity for seamless integration • TAA compliant, meeting Buy American Act requirements for government projects • RoHS/ELV certified for environmental compliance **Applications:** Ideal for fiber-to-the-premises (FTTP) networks, backbone connectivity, campus area networks (CANs), and specialized single-strand applications. The robust construction handles both indoor and outdoor riser installations. **Support & Warranty:** Backed by a 90-day limited warranty and available in custom lengths for specialized requirements.
