The EDFA is good. It easy to install and manage in the rack that bought here, and is solid built. Great products.

Satisfied with this purchase, especially the custom services. Various choices, very considerate, and easy to find what I need.

EDFA often used in relatively long distance transmission, so we customize several different types for our applications. Received them quickly in a promised time, packages are good, thanks.

The in-line EDFA was exactly as described and was delivered without complication! I would definitely recommend this product and this company.

I am totally satisfied with this purchase: the quality of the EDFA is very high, and I have actually no reason to complain. So I'd totally recommend it to other people!
