The JBX88321 ST/ST duplex singlemode fiber patch cable represents a premium solution for fiber optic network infrastructure. This 9-meter cable is engineered to deliver consistent, high-performance signal transmission across enterprise, data center, and telecommunications environments. **Technical Excellence** Constructed with 9/125 singlemode fiber core and G.657.A1 glass fiber specification, this cable offers superior bending characteristics ideal for tight routing scenarios. The 1.8mm outside diameter provides a compact form factor without compromising durability. Performance testing confirms insertion loss of ≤0.35dB (typical 0.15dB) at both 1310nm and 1550nm wavelengths, meeting ANSI/TIA/EIA-455-171-A standards. Return loss specifications of ≥20dB ensure signal integrity across extended network runs. **Standards & Compliance** TAA compliance makes this cable eligible for government and educational institution procurement. Full RoHS/ELV directive compliance meets international environmental standards. The OFNR (Optical Fiber Nonconductive Riser) jacketing rating enables in-building installations with fire safety assurance. Manufactured in multiple locations including Taiwan, US, and China ensures supply chain reliability. **Practical Applications** Ideal for connecting network switches, servers, and telecommunications equipment in enterprises, data centers, and carrier networks. The Type A to B crossover polarity is the standard configuration for most duplex patch cord applications. Custom lengths are available for specific project requirements. **Value & Support** Each cable ships in protective case packaging (10x10x10) and includes a comprehensive 90-day limited warranty. Free standard shipping on orders exceeding $99 reduces total cost of ownership. Available from strategically located distribution centers in California, Texas, and South Carolina for rapid delivery. **Maintenance Note** Maintain connector caps when not in use to prevent dust contamination. Store in cool, dry conditions away from direct sunlight for optimal longevity.
