These modules were immediately picked up by my Ubiquiti switches and routers. Very inexpensive for someone looking to work with SFP and fiber in their home lab, and easily justifiable if you plan to use them in your datacenter or business.

For my media converter, I needed to choose a reliable SFP module - I chose FS and it is a perfect fit. After I plugged the module into my media converter, the link came up immediately, zero packet loss and no delay. Also loving the customer services here!

I tried this AFP connecting a Cisco Meraki Switch to a Cisco Small Business Switch and it linked.

I've now ordered 3 of these, and am using them in Cisco 3650s. As far as I can tell you that they seem to work fine in my switches, and I didn't have to do anything specific on the Cisco for them to recognize them. Good price too.

At first, I was very concerned about the compatibility and quality of third-party optics, but the sale rep Daisy told me the BiDi SFP enjoys 5 years warranty. If any issues occurs, they will help me to refund or replace, so I had a try, and I'm happy that they work as promised. I gave this transceivers a 5 star review because it does the job really well.

Purchasing was excellent with very helpful staff. And the shipping speed is pretty fast.
