The JBX88372 1.5m ST/ST duplex 9/125 singlemode fiber patch cable represents a critical component for modern data center and telecommunications infrastructure. Engineered to exacting standards, this cable delivers the reliability and performance required for mission-critical applications. **Technical Excellence**: Utilizing 9/125 singlemode fiber with G.657.A1 specifications, the cable achieves exceptional attenuation characteristics of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm wavelengths. The measured insertion loss of ≤0.35dB (typically 0.15dB) and return loss ≥20dB ensure minimal signal degradation across network spans. **Professional Features**: ST/UPC connectors with Type A to B crossover polarity provide the standard configuration for duplex patch cord applications. The OFNR riser-rated purple jacket protects the dual-strand core while meeting fire safety requirements for in-wall installations. The compact 1.8mm diameter minimizes space requirements in high-density cable management scenarios. **Compliance & Quality**: TAA compliance satisfies federal procurement standards, while RoHS/ELV certification ensures environmental responsibility. All cables undergo rigorous attenuation testing per ANSI/TIA/EIA-455-171-A standards, guaranteeing consistent quality across production batches. **Versatile Applications**: Ideal for connecting network equipment, telecommunications systems, and fiber distribution panels. The 1.5m length accommodates typical rack-to-rack and equipment-to-cabinet distances. Custom lengths available for specialized deployment requirements. **Reliable Service**: Manufactured in Taiwan, the US, or China with quality assurance oversight, backed by a 90-day limited warranty. Ships from strategically located US warehouses (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on qualifying orders. The duplex construction transmits fiber signals with minimal attenuation, supporting both legacy and modern network protocols requiring singlemode performance.
