Wonderful customer service; my account manager patiently assists me in selecting the appropriate model.

For network upgrades, our data center required some 100G optics. These FS modules appeared to be high-performance which I discovered by chance while searching online. I then made my orders. This 100G ERL optical modules worked extremely well and contributed to the connection in our data center.

we installed our new transceivers from the Dallas order and we did not run into any issues.

Yes, I got the transceivers yesterday. Faster delivery than I expected. So big thumbs up on that.
