      The 10G DWDM I purchased from QSFPTEK was a good replacement for my old H3C transceivers, and the price was a good financial relief for my large order. This batch of transceivers all worked well, and the engineers at QSFPTETK helped us with technical support. We purchased a lot of modules such as CH21 to CH44, and the labels on the modules helped us to be able to correctly identify the transmission channel of the modules.

      I ordered 20pcs. Each worked well on Cisco Nexus 93180YC-FX. The price is much more affordable than the original band of Cisco. I was worried about the compatibility before purchasing, but qsfptek tech engineer waved off my worries by showing me their test report. Thanks.
