The JBX90183 SC/ST Duplex Singlemode Fiber Patch Cable represents professional-quality optical connectivity for demanding telecommunications and data center environments. This 2-meter cable delivers reliable single-mode signal transmission with industry-leading performance specifications. **Key Technical Features:** Built on G.657.A1 glass fiber technology, this duplex patch cable features a 9/125 micrometer core optimized for singlemode applications. The cable supports operation at both 1310 nm and 1550 nm wavelengths with attenuation of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm. Measured insertion loss reaches only ≤0.35dB (0.15dB typical), while return loss exceeds 20dB, ensuring signal integrity across long distances. **Connector Configuration:** The SC/UPC to ST/UPC connector arrangement follows Type A to B crossover polarity—the industry standard for duplex patch cords. This configuration ensures compatibility with most network infrastructure while simplifying installation and maintenance. **Compliance and Standards:** TAA-compliant and RoHS/ELV certified per EU Directive 2002/95/EC, this cable meets stringent environmental and procurement requirements. Performance is verified through ANSI/TIA/EIA-455-171-A-2001 attenuation testing. **Installation and Protection:** The OFNR (Optical Fiber Non-conductive Riser) rated jacket provides fire safety for vertical cable runs and plenum installations. The 1.8mm outside diameter and lightweight plastic accessories ensure easy routing through cable trays and conduit. **Practical Advantages:** The distinctive pink color simplifies cable management and identification in high-density installations. With custom lengths available, this cable adapts to various deployment scenarios. Manufactured in Taiwan, the US, or China with multiple domestic distribution centers, the JBX90183 ships quickly from Danville CA, Fort Worth TX, or Beaufort SC. Standard shipping is free on orders exceeding $99. **Ideal Applications:** Perfect for connecting telecommunications equipment, optical network switches, fiber-to-the-premises installations, and laboratory testing environments where reliable singlemode transmission is essential. The 90-day limited warranty provides peace of mind for critical installations.
