2024-07-02 09:43:11

With the rapid development of the Internet, the market demand for high bandwidth and high reliability is also increasing, so the high-speed interconnection solution of DAC high-speed cable has emerged. Here, 3Coptics introduces 100G QSFP28 DAC high-speed cable.

What is DAC high-speed cable:

DAC high-speed cable (Direct Attach Cable) is generally translated as direct cable or direct copper cable. It is usually a cable assembly with fixed connectors at both ends. The port cannot be replaced, and the module head and copper cable cannot be separated. It is widely used in storage area networks, data centers and high-performance computer connections.
