We use a lot of FS transceiver in different type with different vendors - all of them works well.

The parts we ordered are all working 100%, as expected. We purchased a spare of each, just in case we blow them up, but everything is working as expected.

The items orders are exactly meeting my requirements, the quality is high and the price fair. I'm currently gathering together another order as I'm quite content with the quality I've seen from FS.

Great Compatible item. No issues

Ordering from FS has always been quick and easy! We always receive our items in a very timely manner.

Great product, plug and play!

Great personal service by email!

great service

Works perfecltly as expected, no problem with the router. RX/TX quality is very good

I was skeptical at first about buying a SFP module, but I'm glad I took the plunge. The module is well-built and performs like a champ. I've noticed faster data transfer speeds and less latency on my network.
