The JBX88255 3-meter ST/ST duplex singlemode fiber patch cable represents a robust solution for professional telecommunications and networking infrastructure. Engineered with precision, this cable combines superior optical performance with practical durability for demanding installation environments. **Technical Excellence:** Built with a 9/125 singlemode core and premium G.657.A1 glass fiber, this patch cable delivers industry-leading optical performance. The insertion loss specification of ≤0.35dB (with typical performance at 0.15dB) ensures minimal signal loss, critical for long-distance transmissions. Return loss of ≥20dB provides excellent signal integrity. Attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm comply with stringent telecom standards, making it ideal for both short-reach and long-distance applications. **Connector & Configuration:** Equipped with ST/UPC connectors in the standard Type A to B crossover configuration, this duplex cable accommodates bidirectional signal transmission typical in modern network architectures. The ST connector interface is widely deployed across telecommunications, CATV, and enterprise data center environments. **Regulatory Compliance & Quality Assurance:** TAA compliance ensures government procurement eligibility. Full RoHS/ELV compliance meets environmental regulations. Testing to ANSI/TIA/EIA-455-171-A standards guarantees performance reliability. The 90-day limited warranty provides peace of mind on your investment. **Installation Features:** The compact 1.8mm outer diameter facilitates easy routing through cable trays and conduits. OFNR (riser-rated) jacketing supports both horizontal and vertical installations while maintaining flame-resistance requirements. The blue jacket provides easy identification in complex cable environments. **Applications:** Ideal for telecommunications networks, metropolitan area networks (MANs), wide area network (WAN) connections, data center interconnects, and telecom central offices. Perfect for installations requiring reliable, standards-compliant fiber connectivity. **Availability & Service:** Ships from multiple U.S. distribution centers (Danville, CA; Fort Worth, TX; Beaufort, SC) with free standard shipping on orders over $99. Custom lengths available for specific project requirements.
