Product Overview
The CT QDS400SZPTA00 is a 400G QSFP-DD active optical cable (AOC)
designed for high-speed, high-density, short-reach interconnects
within data centers. It offers a reliable plug-and-play solution
for 400 Gigabit Ethernet connectivity between QSFP-DD ports without
the need for external transceivers or fiber optic patch cords.
Utilizing multimode fiber and integrated optical transceivers, this
AOC provides superior signal integrity and low power consumption,
making it ideal for high-performance computing (HPC), cloud
infrastructure, and enterprise data center applications.
