The JBX43076 represents professional-grade fiber optic connectivity designed for mission-critical applications requiring superior signal integrity and reliability. As a 25-meter LC/APC to SC/UPC simplex singlemode patch cable, it bridges different connector standards while maintaining exceptional optical performance standards. **Technical Specifications & Performance:** This cable utilizes a 9/125 singlemode core construction with G.657.A1 grade glass fiber, specifically engineered for long-distance signal transmission with minimal attenuation. Performance metrics include insertion loss of ≤0.35dB at typical operation (0.15dB nominal) and return loss exceeding 20dB, exceeding ANSI/TIA/EIA-455-171-A-2001 standards. Attenuation rates measure 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm, ensuring consistent performance across telecommunications wavelengths. **Compliance & Safety Features:** Full TAA (Trade Agreements Act) compliance makes this cable suitable for government and federal procurement requirements. RoHS and EU directive 2002/95/EC compliance ensures environmental responsibility. OFNR (Optical Fiber Nonconductive Riser) rated jacketing permits safe use in building risers and plenum areas, with 1.8mm outside diameter construction providing durability and easy routing through cable trays and conduits. **Applications & Use Cases:** Ideal for telecommunications facilities, data centers, server room installations, and network backbone connections. The LC/APC to SC/UPC connector configuration addresses legacy system integration while LC/APC connectors provide superior return loss characteristics. Simplex configuration suits unidirectional signal transmission applications. **Practical Advantages:** Distinctive yellow jacket enables quick identification in complex cable installations. Available in custom lengths for specific deployment requirements. Ships from three US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery. Backed by comprehensive 90-day limited warranty covering manufacturing defects. **Installation Recommendations:** Handle connectors with care to maintain optimal performance. Keep protective caps installed when not connected. Store in clean, dry environments. Professional installation recommended for mission-critical applications to ensure proper termination and alignment.
