The JBX90195 20m SC/ST Duplex Singlemode Fiber Patch Cable represents a professional-grade solution for organizations requiring reliable, high-performance fiber optic connectivity. This cable is engineered to meet the stringent demands of data centers, telecommunications infrastructure, and enterprise network environments. Key Technical Features: This duplex patch cable features dual 9/125 singlemode fiber strands constructed with G.657.A1 glass technology, enabling long-distance signal transmission with minimal loss. The SC/UPC to ST/UPC connector configuration provides Type A to B crossover polarity, the industry-standard arrangement for duplex patch cords. Testing according to ANSI/TIA/EIA-455-171-A standards confirms insertion loss of ≤0.35dB (typical 0.15dB) and return loss exceeding 20dB, ensuring superior signal integrity. Robust Construction: The 1.8mm outer diameter cable features OFNR (Optical Fiber Non-conductive Riser-rated) jacketing, meeting critical building codes for plenum and riser installations. The pink color finish aids in visual network organization and identification. Plastic accessories ensure durability while maintaining compliance with RoHS/ELV environmental directives. Compliance & Warranty: TAA compliance makes this cable eligible for government and educational procurement programs. The 90-day limited warranty provides confidence in product reliability. Custom lengths are available for non-standard applications. Applications: Ideal for fiber-to-the-premises (FTTP) installations, network switches, optical transceivers, and telecommunications equipment connections requiring singlemode performance. Free standard shipping applies to orders exceeding $99, with fulfillment from multiple U.S. locations ensuring rapid delivery.
