The JBX42018 fiber patch cable represents a professional solution for demanding telecommunications and data center applications requiring high-performance single mode fiber connectivity. Spanning 35 meters, this duplex cable features dual strands of 9/125 single mode fiber, providing the optimal balance of bandwidth capacity and compatibility with industry-standard network infrastructure. Construction and Materials: This cable utilizes premium G.657.A1 glass fiber wrapped in a robust OFNR (riser-rated) polyvinyl chloride jacket with 1.8mm outside diameter. The yellow coloring provides superior visibility during installations and maintenance, facilitating quick identification in crowded cable trays or wall conduits. The duplex configuration with two parallel fibers enables simultaneous bidirectional communication, essential for full-duplex network protocols. Connector Technology: Features LC/APC (Angled Physical Contact) termination on one end and LC/UPC (Ultra Physical Contact) on the other, configured as Type A to B crossover—the industry standard for duplex patch cords. This configuration eliminates the need for additional crossover hardware and simplifies network topology. Performance Specifications: Tested in accordance with ANSI/TIA/EIA standards, the cable delivers exceptional performance metrics: insertion loss ≤0.35dB (0.15dB typical) and return loss ≥20dB. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure minimal signal degradation across the full 35-meter span, critical for maintaining link budgets in optical networks. Compliance and Standards: TAA (Trade Agreements Act) compliant for government procurement. RoHS/ELV certified per EU directive 2002/95/EC, meeting environmental regulations. Manufactured in Taiwan, the United States, or China with consistent quality standards. Applications: Ideal for data centers, telecommunications facilities, enterprise networks, and any installation requiring reliable single mode fiber connectivity over 35-meter distances. Particularly suitable for connections between network switches, routers, and optical transceivers. Customization and Support: Available in custom lengths to match specific installation requirements. Backed by a 90-day limited warranty. Ships from three US distribution centers (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99.
