The JBX87178 85-meter SC/SC duplex singlemode fiber patch cable is engineered for professional network environments demanding extended reach and exceptional signal fidelity. This premium optical accessory delivers reliable fiber optic connectivity across substantial distances, making it ideal for campus networks, data center interconnections, and telecommunications infrastructure. **Technical Excellence** Constructed with 9/125 singlemode fiber, this cable provides superior performance for long-distance transmission. The G.657.A1 bend-insensitive glass fiber reduces macro-bending losses, enabling easier installation around tight corners and congested cable routes without signal degradation. Attenuation specifications of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm ensure minimal signal loss across the cable length. With insertion loss ≤0.35dB (0.15dB typical) and return loss ≥20dB, the SC/UPC connectors maintain exceptional optical performance verified through ANSI/TIA/EIA-455-171-A-2001 testing. **Safety & Compliance** TAA (Trade Agreements Act) compliance makes this cable suitable for government and regulated procurement environments. The OFNR (Optical Fiber Non-conductive Riser) jacket rating ensures fire safety in multi-story commercial installations. RoHS/ELV compliance eliminates hazardous substances, supporting corporate sustainability initiatives and regulatory requirements. **Installation Flexibility** The duplex configuration with Type A to B crossover polarity provides the most common patch cord arrangement for seamless network integration. At 1.8mm outer diameter, the cable navigates standard conduit systems efficiently. Custom lengths are available for specific project requirements beyond the standard 85-meter offering. **Value Proposition** Ships from three US locations (Danville CA, Fort Worth TX, and Beaufort SC) for expedited delivery. Free standard shipping on orders exceeding $99 reduces total acquisition costs. The 90-day limited warranty provides peace of mind for mission-critical installations. Whether upgrading legacy systems or building new fiber infrastructure, this TAA-compliant singlemode cable delivers professional-grade performance at competitive pricing.
