The JBX92201 is a premium-grade 50-meter SC/ST duplex singlemode fiber patch cable designed for mission-critical network infrastructure. Built with precision-aligned 9/125 singlemode fiber core and premium G.657.A1 glass fiber, this cable excels in high-bandwidth, long-distance telecommunications applications. **Key Technical Specifications:** This duplex configuration features SC/UPC and ST/UPC connectors in the most common Type A to B crossover polarity, enabling seamless integration with existing network infrastructure. Attenuation performance meets rigorous standards: 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm wavelengths. The cable's insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB ensure minimal signal degradation across the entire 50-meter span. **Construction & Compliance:** Manufactured with OFNR riser-rated jacketing, the 1.8mm outer diameter cable provides excellent flame resistance suitable for commercial building installations. TAA compliance ensures eligibility for government procurement, while RoHS/ELV certification guarantees environmental responsibility. Standards compliance testing follows ANSI/TIA/EIA-455-171-A-2001 specifications. **Applications & Benefits:** Ideal for data centers, telecommunications facilities, campus networks, and enterprise installations requiring reliable single-mode fiber connectivity. The compact profile allows flexible routing through conduit and cable trays. Custom lengths available to accommodate specific deployment requirements. **Warranty & Support:** Backed by a comprehensive 90-day limited warranty. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Available for immediate deployment in network modernization projects.
