Introduction to QDD 400G FR4

QDD 400G FR4 is a high - speed optical transceiver technology. The "400G" indicates a data transmission rate of 400 gigabits per second, which is crucial for meeting the ever - increasing demand for high - speed data transfer in modern communication networks, such as data centers, high - performance computing, and 5G backhaul. The "FR4" refers to a specific type of fiber - optic reach, typically suitable for short - to - medium - distance transmissions, usually up to 2 kilometers.


QDD (Quad Density Dual) technology further enhances the efficiency and density of the transceiver, allowing for more data to be transmitted in a smaller form factor. This technology is essential for optimizing the use of space and resources in data centers and other high - traffic communication environments.
