The JBX89197 SC/ST duplex singlemode fiber patch cable represents a premium solution for professional optical network deployments. Designed to meet the rigorous demands of datacenter, telecommunications, and enterprise environments, this 30-meter cable combines advanced optical specifications with practical installation features. **Technical Excellence:** Built with 9/125 singlemode fiber core and G.657.A1 glass fiber technology, the cable delivers superior signal integrity across standard telecom wavelengths. Insertion loss measurements of ≤0.35dB (typical 0.15dB) ensure minimal power loss, while return loss exceeding 20dB maintains signal quality. These performance metrics are validated through ANSI/TIA/EIA-455-171-A-2001 standard attenuation testing at both 1310nm and 1550nm wavelengths, accommodating diverse optical systems. **Connector Configuration:** The SC/UPC to ST/UPC connector pairing with Type A to B crossover polarity represents the most common duplex patch cord configuration in the industry. This design facilitates straightforward integration into existing network architectures while supporting full-duplex data transmission. Both connector types feature UPC (Ultra Physical Contact) polish for optimal return loss performance. **Installation & Compliance:** The compact 1.8mm outer diameter with riser-rated (OFNR) jacketing balances durability with installation flexibility, fitting easily through cable trays and conduit systems. Full TAA compliance and RoHS/ELV certification align with government contracting requirements and environmental regulations. The plastic accessory construction maintains cost-effectiveness without compromising performance. **Deployment Applications:** Ideal for interconnecting network equipment in server rooms, telecommunication facilities, fiber-to-the-premises (FTTP) installations, and campus area networks. The 30-meter length addresses both short-distance backbone runs and longer horizontal cable routing requirements. **Flexibility & Support:** Custom lengths are available for non-standard installations, providing scalability across various network topologies. The 90-day limited warranty backs your investment, and free standard shipping on orders exceeding $99 reduces total acquisition costs. Ships from strategically located U.S. distribution centers (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery. **Care & Maintenance:** Protect cable ends with dust caps when not in use. Avoid sharp bends exceeding the minimum bend radius, and store in dry conditions. Regular inspection ensures connector cleanliness for optimal signal transmission.
