The JBX88355 ST/ST duplex singlemode fiber patch cable represents professional-grade connectivity for demanding network environments. Manufactured with precision and compliance to the highest standards, this 20-meter cable delivers reliable, high-speed signal transmission essential for modern data centers, telecommunications infrastructure, and enterprise networks. **Technical Excellence** This singlemode cable features a 9/125 micron core utilizing G.657.A1 glass fiber technology, ensuring minimal signal loss and maximum data integrity. With insertion loss specifications of ≤0.35dB at 1550nm (typical 0.15dB) and return loss ≥20dB, the cable exceeds industry requirements for long-distance, high-bandwidth applications. The cable's attenuation specifications—0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm—make it suitable for extended network runs without signal degradation. **Safety and Compliance** Fully TAA compliant and RoHS/ELV certified per EU directive 2002/95/EC, ensuring compatibility with government and enterprise procurement requirements. The OFNR (Optical Fiber Non-conductive Riser) rating provides fire-safety compliance for in-building installations, making it suitable for vertical cable runs and plenum spaces. **Practical Design** The Type A to B crossover configuration represents the industry standard for duplex patch cord applications. The white color facilitates easy identification in complex cabling environments. The 1.8mm outside diameter balances durability with installation flexibility, enabling clean cable management in crowded server racks and distribution frames. **Value Proposition** Shipped from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders over $99. Custom lengths available for specialized applications. Backed by a 90-day limited warranty, this cable represents a cost-effective investment in reliable network infrastructure. Whether upgrading existing systems or deploying new installations, the JBX88355 delivers professional performance and peace of mind.
