The JBX93174 SC/SC Duplex Singlemode Fiber Patch Cable represents a premium connectivity solution for professional networking environments requiring reliable, high-speed fiber optic transmission. This 65-meter cable combines proven SC/UPC connector technology with advanced singlemode fiber specifications to deliver consistent performance in demanding applications. **Technical Specifications:** The cable features a 9/125 singlemode core with G.657.A1 glass fiber construction, offering exceptional optical characteristics across standard telecom wavelengths. Insertion loss is rated at ≤0.35dB typical (0.15dB), with return loss exceeding 20dB. Attenuation performance meets demanding requirements: 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm, certified to ANSI/TIA/EIA-455-171-A standards. **Construction & Safety:** The 1.8mm diameter cable features OFNR (Riser Rated) jacketing, complying with fire safety codes for installation in building risers and plenums. The orange jacket provides excellent visibility in complex infrastructure, reducing installation time and maintenance errors. RoHS/ELV compliance ensures environmental responsibility. **Compliance & Standards:** TAA compliance makes this cable eligible for government contracts and procurement. Type A to B crossover polarity (standard duplex configuration) ensures compatibility with most enterprise equipment. Tested and certified to industry standards. **Applications:** Ideal for data center interconnects, campus backbone installations, telecommunications environments, and enterprise network upgrades. The 65-meter length accommodates moderate-distance runs without splicing. **Customization & Support:** Custom lengths are available to match specific installation requirements. Quick standard shipping and free shipping on orders over $99. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC). 90-day limited warranty provides peace of mind. **Maintenance Considerations:** Keep connectors clean using lint-free wipes and approved fiber cleaning solutions. Avoid bending below the minimum bend radius (approximately 15mm for singlemode) to prevent signal degradation. Store in protective coils when not in use.
