Product Overview
SN Fiber Optic Patch Cords are high-density duplex fiber cables designed for next-generation data center networks, especially 400G and 800G high-speed transmission environments.
The SN connector is a Base-2 interface that combines compact size with carrier-grade optical performance. It enables network operators to significantly increase port density while maintaining stable signal transmission and long-term reliability.
SN Fiber Optic Patch Cords are widely used in hyperscale data centers, cloud computing platforms, and AI clusters where space is limited and bandwidth demand is continuously increasing. Compared with traditional LC patch cords, SN solutions offer higher density and improved cable management efficiency.
At Spring Optical, all SN Fiber Optic Patch Cords are manufactured under strict quality control and comply with international standards such as TIA-604 (FOCIS) and IEC 61754. Each connector is fully tested to ensure low insertion loss and consistent performance.
These patch cords support multiple fiber types including OS2, OM1, OM2, OM3, OM4, and OM5, making them suitable for Gigabit Ethernet, 10G, 40G, 100G, and high-speed Fiber Channel applications.
