The JBX91184 SC/ST duplex singlemode fiber patch cable represents professional-grade connectivity for modern telecommunications and data center infrastructure. This 2.5-meter cable delivers superior performance with its 9/125 singlemode core and advanced G.657.A1 glass fiber construction, specifically designed to minimize signal loss and maximize transmission reliability. **Technical Excellence** Measuring just 1.8mm in outer diameter, this cable achieves exceptional insertion loss performance of ≤0.35dB (typical 0.15dB) and return loss exceeding 20dB. Performance testing follows rigorous ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality across attenuation frequencies (1310nm: 0.25dB/km and 1550nm: 0.35dB/km). The duplex configuration with SC/UPC to ST/UPC connectors in Type A to B crossover polarity makes this cable immediately compatible with most duplex patch cord applications. **Compliance & Durability** Full TAA compliance ensures procurement eligibility for government contracts and regulated industries. RoHS/ELV directive compliance (EU 2002/95/EC) reflects environmental responsibility without compromising performance. OFNR riser-rated jacketing provides flame resistance and code compliance for building installations, while plastic accessories ensure longevity in diverse environments. **Practical Applications** Ideal for connecting network equipment in data centers, telecommunications facilities, and enterprise campuses. The compact 1.8mm profile facilitates installation in cable trays and tight routing scenarios. Custom length availability accommodates specific installation requirements beyond standard configurations. **Quality Assurance** Every cable includes a 90-day limited warranty, backed by multiple US distribution locations ensuring rapid availability. Free standard shipping on orders exceeding $99 reduces total acquisition costs. Whether upgrading existing infrastructure or building new networks, this cable delivers the performance, reliability, and compliance required by professionals. **Maintenance Note** Maintain SC/ST connector cleanliness using appropriate fiber cleaning tools. Avoid bending below the cable's minimum bend radius (approximately 10cm) to preserve fiber integrity and performance characteristics.
