Every Module works fine without any error.

The connect does look good. We appreciate your ability to get what we need and how capable your company is.

Paired with the SMF cable recommended in the page. Their team always replied within 24 hours, and they were really knowledgeable in their responses.

At 400 GB speed, it really reduces the amount of time needed to copy photos from my iphone the SAN on the other side of the data-center all over a SMF pair! Would recommend ;-

We purchased this QSFP-DD optical module here and one 400G switch from another vendor. The module has very good packages and has been delivered quickly, but our network switches are on the delivery way...

400G LR8 QSFP-DD is brand new. I’m very interested in it and I’ve been focusing on their news. Once they promoted it on their site, I asked my account manager if they can provide it. He answered yes. Now I’m very glad to receive this transceiver. I Hope FS can serve more products like this then I don’t need to look around.
