    Just a quick note to say we started using the transceivers today and they’re working well. I was counting on them to perform, and they turned out to be exactly what we needed. Many thanks!

    We installed these 100G LR4 modules to link two of our data centers, and they’ve been working great. Plug-and-play with no headaches, and the signal has been clean even over long distances.

    Updated to the QSFP28 100G module product, compared to the previous CFP, the product design is compact, which saves some space for our cabinet, and the product is plug and play, which is very simple and convenient to use.

    We have purchased batches of 100G-LR4 for data center-level projects. This batch of modules has been used in full-duplex mode for a week, and the performance is very stable, which is not inferior to other original Cisco brand modules in the data center, which surprises me.

    Most of my modules are the ones from FS but these are cheaper than FS. I'm really happy with these optics.
