Product Overview
The MPO to SN Cassette Module is a next-generation VSFF (Very Small Form Factor) fiber optic cassette solution designed for 400G, 800G, and future 1.6T data center interconnect architectures.
It converts a single MPO/MTP® backbone connection into multiple SN duplex ports, enabling ultra-high-density fiber breakout in modern switch and patch panel systems.
Compared with traditional LC-based solutions, the SN interface significantly reduces connector footprint while improving airflow efficiency and enabling higher port density in space-constrained environments.
This solution is widely used in hyperscale data centers, AI computing clusters, and high-speed optical interconnect networks, where scalability and rack efficiency are critical.
As a professional fiber optic manufacturer, Spring Optical provides factory-terminated, low-loss MPO to SN Cassette modules designed for stable long-term performance in mission-critical optical networks.
