These are brilliant. Now our office network is blazing fast. I have used these in our firm for about 3 months, and so far, excellent performance is obvious. No complaints or issues whatsoever.

These modules were immediately picked up by my Cisco switch and Cisco router. After I plugged it into the port, the link promptly came up. Zero packet loss and no delay. Pretty high quality for someone who is looking to work with SFP and fiber in their project.

It was easy to search all the items that I needed and had plenty of info on all items.

Good quality transceiver, fully compatible to my cisco switch. Will be back for more.

80km SFP module with such a favorable price is great. We will order more.

It's easy to find the module that we want. And the module is compatible with our switch.
