The JBX89179 SC/SC duplex singlemode fiber patch cable represents professional-grade connectivity for modern telecommunications and data center infrastructure. Designed specifically for single-mode applications, this 90-meter cable delivers consistent, high-performance signal transmission over extended distances with minimal attenuation. **Technical Specifications:** This cable utilizes a 9/125 micrometer fiber core with G.657.A1 glass composition, optimized for single-mode operation. Attenuation performance meets stringent standards at 1310 nm (0.25 dB/km) and 1550 nm (0.35 dB/km) wavelengths. With typical insertion loss of just 0.15dB and maximum 0.35dB, combined with return loss exceeding 20dB, the cable ensures reliable signal integrity across long distances. **Key Features:** - TAA-compliant for government and enterprise procurement - OFNR riser-rated jacketing for safe installation in building pathways - Type A to B crossover configuration for standard duplex patch applications - RoHS/ELV compliant, meeting EU environmental directives - Compact 1.8mm outer diameter for space-efficient routing - Purple color for easy identification and network management **Applications:** Ideal for telecommunications networks, data center interconnects, fiber-to-the-premises (FTTP) installations, and long-distance network backbones. The 90-meter length accommodates large facility deployments, server rooms, and campus-wide fiber networks. **Quality Assurance:** Manufactured to ANSI/TIA/EIA-455-171-A standards with attenuation testing, this cable delivers consistent performance. Multi-facility sourcing (Taiwan, US, China) ensures reliable supply and quality consistency. **Ordering Benefits:** Free standard shipping on orders exceeding $99 from strategically located distribution centers. Custom lengths available upon request for specialized applications. 90-day limited warranty provides peace of mind for mission-critical installations.
