The JBX88245 70-meter ST/ST duplex singlemode fiber patch cable represents the gold standard in professional-grade optical connectivity. Designed and tested to rigorous telecommunications industry standards, this cable delivers the performance, reliability, and compliance requirements demanded by network professionals and system integrators. **Core Specifications & Performance:** Features a 9/125 micrometer core with G.657.A1 glass fiber construction, providing exceptional signal integrity over extended distances. The cable achieves insertion loss of just ≤0.35dB (typical 0.15dB) and return loss exceeding 20dB—specifications tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. These performance metrics translate to minimal signal degradation and superior connection quality. **Design & Construction:** The cable utilizes ST/UPC connectors with Type A to B crossover polarity, the most common configuration for duplex patch cord applications. The compact 1.8mm outside diameter facilitates easy routing through cable trays and conduit. OFNR riser-rated jacketing ensures compliance with building fire codes and safety requirements, making this cable suitable for vertical runs in commercial buildings and data centers. **Compliance & Certification:** TAA compliant and certified under RoHS/ELV directives (EU 2002/95/EC), this cable meets federal procurement standards and environmental regulations. Manufactured in Taiwan, the United States, and China, with inventory maintained in multiple distribution centers (Danville CA, Fort Worth TX, and Beaufort SC). **Applications:** Ideal for telecommunications networks, data center interconnects, enterprise LANs, campus networks, and any application requiring reliable singlemode fiber connectivity. The 70-meter length accommodates medium-distance facility runs while minimizing signal loss. **Ordering Flexibility:** Custom lengths available for specialized installations. Free standard shipping on orders exceeding $99. 90-day limited warranty provides peace of mind. Individually packaged for safe shipping and storage.
