Dell C58 DWDM-SFP25G-31.12互換 25G DWDM SFP28モジュール(100GHz 1531.12nm 10km DOM)

My overall feeling about these transceivers was pretty good. I had been using these modules for nearly two months, and everything was fine. Initially, I wasn’t quite sure whether the modules could be used on my Cisco switch. So I told my AM the detailed type of my switch. She helped me find the suitable modules together with the technical team. Both of them were very patient and warmhearted. No matter what kinds of questions I asked, they always replied with details promptly. The packaging was super nice with no damages. And there was no difference with the picture shown on the website. These transceivers worked well with my switch. The signal transmission was stable and there was no signal loss or module failure. Five stars!
