    Our company recently adopted 40G AOC as the main connection method of the data center, and the effect is very significant. Compared with traditional copper cables, 40G AOC not only provides higher transmission rates, but is also easier to install and manage. Especially in high-density network environments, it can effectively reduce electromagnetic interference and ensure the stability of data transmission.

    This is the second time I buy it, because the first one is really good, I bought 10 this time, I haven't used it yet, but I believe the quality must be very good, I will buy it again.
