The JBX43075 20m LC/APC to SC/UPC Simplex Singlemode Fiber Patch Cable is a precision-engineered optical connectivity solution designed for telecommunications professionals, data center technicians, and network integrators. This cable delivers exceptional performance characteristics backed by rigorous testing standards. **Technical Specifications:** Features a 9/125 micrometer singlemode fiber core with G.657.A1 glass specification, enabling superior light transmission over extended distances. The insertion loss rating of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while the return loss of ≥20dB prevents reflective interference. Testing conducted per ANSI/TIA/EIA-455-171-A-2001 standards guarantees consistency and reliability. **Connector Configuration:** LC/APC (Angled Physical Contact) connectors on one end and SC/UPC (Straight Physical Contact) connectors on the other enable seamless integration between diverse equipment types. APC connectors reduce back reflection, ideal for sensitive applications requiring low-loss performance. **Quality & Compliance:** TAA compliant for U.S. government procurement. RoHS/ELV certified ensuring environmental safety. The 1.8mm outer diameter cable features a riser-rated (OFNR) yellow polyvinyl chloride jacket for easy identification, workplace safety, and building code compliance. **Applications:** Perfect for connecting switches, routers, and optical transceivers in telecommunications networks, CATV facilities, and data center environments. The 20-meter length accommodates moderate-distance runs within equipment racks and between nearby network nodes. **Value Proposition:** Competitively priced with free standard shipping on orders exceeding $99. Available in custom lengths for specialized requirements. Includes 90-day limited warranty. Multiple U.S. warehouse locations ensure fast, reliable delivery. Ships from Danville CA, Fort Worth TX, or Beaufort SC.
