The JBX43731 SC/APC to LC/UPC simplex fiber patch cable represents a professional-grade solution for organizations requiring TAA-compliant, high-performance fiber optic connectivity. This 50-meter pre-terminated cable seamlessly bridges SC/APC and LC/UPC connector architectures, making it an essential component for mixed-network environments and system upgrades. **Superior Performance Characteristics:** Engineered with 9/125 singlemode fiber core (G.657.A1 specification), this cable delivers exceptional signal integrity over extended distances. The measured insertion loss of ≤0.35dB (typical 0.15dB) ensures minimal signal degradation, while the ≥20dB return loss performance exceeds industry standards for optical quality. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm accommodate both traditional and advanced wavelength division multiplexing applications. **Regulatory Compliance & Safety:** Fully TAA (Trade Agreements Act) compliant, this cable meets federal procurement requirements for government and regulated sectors. RoHS/ELV directive compliance (EU 2002/95/EC) ensures environmental responsibility. The riser-rated OFNR jacketing provides fire-safety certification for indoor building installations, while the yellow outer jacket facilitates quick identification and organized cable management in complex network infrastructures. **Construction & Durability:** Manufactured with precision-molded plastic connectors and high-quality optical components, the cable features a compact 1.8mm outside diameter for flexible routing through cable trays and conduit systems. The robust construction, combined with a 90-day limited warranty, provides confidence in long-term reliability. **Applications & Use Cases:** Ideal for data center expansions, telecommunications facilities, enterprise network upgrades, and any installation requiring mixed SC and LC connector architectures. The 50-meter length eliminates the need for multiple shorter segments, reducing connection points and improving overall system reliability. **Shipping & Availability:** Ships from strategically located US facilities (Danville CA, Fort Worth TX, and Beaufort SC) with complimentary standard shipping on orders exceeding $99. Custom lengths available upon request. Packaged in protective 10x10x10 cases for secure transit. **Standards Compliance:** Attenuation performance independently tested per ANSI/TIA/EIA-455-171-A-2001 standards, ensuring verified quality and consistency. Compatible with standard single-mode fiber optic systems requiring SC/APC and LC/UPC connectivity.
