Very good quality and prompt delivery.

Exactly what I needed for my 40 Gbit/s Infiniband network. Have installed it under the house and it is working well. Shipping from Wuhan to New Zealand was only a week - excellent!

we are with these people since early 2019. Never did we have to complain about their service or products, just keep it up guyz.

Just to let you know that all the cables we ordered from you for our project have been installed and our customer seems to be happy with everything, thank you very much for getting this order dealt with so quickly. We are very happy with the service you gave us.

We use IBM QSFP EB59, namely FINISAR 100G QSFP28 optical transceiver FTLC9558REPM. The type B MTP 12F you recommended is very suitable for connecting our Broadcom module.

I manually placed an order for the product, but to my disappointment, I found there was a compatibility issue upon receiving the goods. I contacted my account manager and he quickly resolved the issue and informed me of the correct product pairing.

If you have purchased an A-polarity cassette and a B-polarity jumper, be sure to insert the 1st interface into the -12th interface.
Of course, if you have purchased an A-polarity cassette, an A-polarity jumper, and an AF-polarity cassette, then congratulations! You have successfully purchased the correct products.
