Blitzversand, das Paket war am nächsten Tag da.Blitzende Lieferung, es funktioniert einwandfrei.

Got these to be used on my Cisco switches for 100G direct connection. Happy to see that switch management software recognized them and each of them works. Never had a single issue. Will continue to buy products from FS next time.

I had a wonderful experience ordering from FS. I got my order within a week. I will be looking for more good deals with you. It would be much better to switch to another cheaper shipping method.

I hot plugged the QSFP28 dual-rate transceiver into the Cisco C9500-24Y4C and it worked.

For such a long connection distance, we are definitely quite careful about making decisions. Before this, we have bought transceivers here for several times. Their product quality and services both impressed us. So after comparison, this time we choose FS again. It turns out to be a wise buying. Overall, the transmission efficiency is good.

This dual-rate module works great for our network. It’s quite suitable for our high-speed connections. We choose it for future network upgrading and cost-saving. What we care about most is stability. To our satisfaction, it has stood the tests.

Отличный продукт. Это было именно то, что я искал, и я был очень доволен качеством. Это намного превзошло мои ожидания! Я настоятельно рекомендую это всем.

I ordered the QSFP-100G-ER4-D40 and SOA. Installed the SOA module in front of the receiver of the 100G transceiver. 40 km distance can be covered with this pair combination.

We have kept some genuine modules of each type/brand so we can swap them out for testing, but the modules serving on the rack are all from FS.com. They are just as good as the original modules.

Everything is fine with this 100G dual rate trasceiver. It goes well on my Cisco switches. I was also impressed by their services. They always answered my questions in no time and also helped me finish the configuration. Many thanks...
