    I bought these modules for regular replacements in our server rooms. I was a bit skeptical at first since it was a new brand for me, but they’ve exceeded my expectations! They arrived just four days after I ordered them, and the packaging was great. I've been using them with switches from Cisco, Arista, H3C, and more for the past two weeks, and so far, everything's running smoothly with no errors.

    The switch detected the optics in a second. They always produce quality transceivers, with no complaints.

    Not the first time to buy from QSFPTEK. Plugged in and got 1000Mbps, no exceptions. The modules are working stably on my switches. Recommended for the price and quality.

    The price is cheaper than other big brands. I think this 1G optical module is a relatively common product, so there is no need to buy expensive ones.
