The JBX87040 8-meter LC/SC duplex singlemode fiber patch cable represents enterprise-class networking infrastructure designed for demanding telecommunications, data center, and network backbone applications. This precision-engineered cable combines cutting-edge fiber optic technology with stringent compliance standards to meet the needs of IT professionals and network engineers. **Core Technical Specifications** Constructed from premium G.657.A1 singlemode fiber with 9/125 micron core/cladding dimensions, this cable delivers minimal signal degradation across standard telecommunications wavelengths. The measured attenuation of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensures signal fidelity over extended distances. With insertion loss maintained at ≤0.35dB (typical performance at 0.15dB), the cable exceeds industry expectations for signal preservation. Return loss specifications of ≥20dB provide excellent reflection suppression, critical for maintaining signal quality in bidirectional communications. **Connector Architecture** LC/UPC to SC/UPC connector configuration with Type A to B crossover polarity is engineered for seamless integration with standard network equipment. Both connector types feature ultra-polished contact surfaces that minimize signal reflection and maximize coupling efficiency. The duplex design accommodates full-duplex communication on a single cable run. **Build Quality and Installation** The 1.8mm diameter OFNR-rated jacket provides flame resistance suitable for plenum and riser installations in commercial buildings. Durable plastic construction protects the fiber core while maintaining flexibility for routing through conduit and cable trays. The cable is individually tested to ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent performance across every unit. **Compliance and Standards** Full TAA (Trade Agreements Act) compliance makes this cable ideal for government and institutional procurement. RoHS/ELV certification confirms environmental responsibility through restriction of hazardous substances. Manufacturing in Taiwan, USA, and China ensures supply chain reliability with domestic options available. **Customization and Support** While this 8-meter configuration addresses most standard installations, custom lengths are available for specialized requirements. The 90-day limited warranty provides peace of mind, and free standard shipping on orders over $99 reduces total cost of ownership. With warehouses in Danville CA, Fort Worth TX, and Beaufort SC, rapid fulfillment is assured for urgent deployments. **Applications** Ideally suited for LAN backbone connections, telecommunications room patch panels, equipment interconnections, and fiber-to-the-desk implementations requiring singlemode performance.
