Product Overview
The MPO to CS Cassette Module is a next-generation high-density fiber optic solution designed for 400G and 800G data center networks. It converts a single MPO/MTP® trunk connection into multiple CS duplex ports, enabling ultra-efficient fiber breakout in modern hyperscale and AI-driven network architectures.
With the rapid evolution from 100G to 400G and 800G Ethernet, traditional LC-based systems are reaching density limitations. The CS connector-based cassette solves this challenge by delivering significantly higher port density, reduced footprint, and improved airflow performance.
This makes it an ideal solution for:
Hyperscale data centers
Spine-leaf architectures
AI computing clusters
High-speed cloud interconnects
As a professional MPO to CS Cassette manufacturer, Spring Optical provides factory-terminated, low-loss, and fully tested modules for mission-critical optical infrastructure.
