The JBX87036 4-meter LC/SC duplex singlemode fiber patch cable represents the gold standard for fiber optic connectivity in professional networking applications. This high-performance cable combines precision engineering with rigorous quality standards to deliver uncompromising signal integrity. **Technical Specifications:** At its core lies a 9/125 singlemode fiber constructed from G.657.A1 grade glass—a specification optimized for minimal bend-radius sensitivity while maintaining long-distance transmission capabilities. The cable achieves exceptional attenuation performance of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm, making it ideal for both short-haul and long-distance applications. With insertion loss typically measuring just 0.15dB and a minimum return loss of 20dB, this cable minimizes signal degradation and reflective losses. **Key Features & Benefits:** The duplex configuration with LC/UPC to SC/UPC connectors provides maximum flexibility for diverse network architectures. The Type A to B crossover polarity ensures proper signal routing in standard telecommunications installations. The blue OFNR (Optical Fiber Non-conductive Riser) rated jacket complies with fire safety codes, making it suitable for plenum-adjacent and vertical runs in multi-story installations. **TAA Compliance & Government Standards:** Fully compliant with the Trade Agreements Act, this cable qualifies for government and federal procurement programs. Additionally, RoHS/ELV certification ensures environmental responsibility and regulatory compliance across international markets. **Applications:** Perfect for data center interconnects, telecommunications networks, broadcast facilities, and enterprise backbone installations. The 4-meter length accommodates medium-distance patch runs between equipment racks, switches, and network infrastructure. **Quality Assurance:** Every cable undergoes rigorous attenuation testing per ANSI/TIA/EIA-455-171-A standards, with comprehensive documentation available. The 90-day limited warranty provides peace of mind. **Customization & Shipping:** Custom lengths available to meet exact installation requirements. Free standard shipping on orders exceeding $99, with fulfillment from multiple distribution centers (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery. The compact 1.8mm diameter facilitates easy routing through cable trays and conduits while maintaining performance integrity.
