The JBX42986 25-meter LC/UPC to LC/UPC simplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical fiber optic networks. This cable is specifically designed for telecommunications professionals, data center operators, and network integrators who demand exceptional reliability and performance. **Technical Excellence:** Featuring a 9/125 singlemode fiber core with G.657.A1 glass specification, this cable provides superior performance characteristics. The low insertion loss of ≤0.35dB (with typical performance of 0.15dB at installation) ensures minimal signal degradation over the 25-meter run. Return loss specifications of ≥20dB guarantee excellent signal integrity. Attenuation measurements comply with ANSI/TIA/EIA-455-171-A-2001 standards at both 1310nm and 1550nm wavelengths. **Durability and Compliance:** The yellow riser-rated OFNR jacket provides robust protection while maintaining fire code compliance for building installations. With a compact 1.8mm outer diameter, the cable integrates seamlessly into existing infrastructure. The cable is TAA (Trade Agreements Act) compliant, making it suitable for government and institutional procurement. RoHS/ELV certification ensures environmental compliance across global markets. **Versatile Applications:** Ideal for telecommunications networks, enterprise data centers, campus networking, and fiber optic backbone infrastructure. The simplex configuration supports single-direction signal transmission, suitable for applications utilizing separate send and receive paths or bi-directional equipment. **Quality Assurance:** Backed by a 90-day limited warranty and manufactured in Taiwan, the US, or China. The cable ships from multiple US locations (Danville CA, Fort Worth TX, or Beaufort SC), ensuring fast delivery. Custom lengths are available to accommodate specific installation requirements. **Care and Maintenance:** Protect connectors with dust caps when not in use. Store in a cool, dry environment away from extreme temperatures or direct sunlight. Clean connectors with appropriate fiber optic cleaning materials before installation. Avoid excessive bending that may exceed the cable's minimum bend radius specifications.
