I'm happy to tell you that the tunable dispersion modules we bought from you are working fine, and we would like to establish our experiments further using tunable dispersion modules.

To better regulate and manage the system, I chose this TDCM to compensate for the extra dispersion. So far it's working well.

There were some problems in my link, the fiber had been used for a long time. So I needed a dispersion compensation module to compensate for about 10km SMF-28e fiber, it was hard to buy a suitable product. Luckily, I found this TDCM, and I can easily adjust compensation to the value I want. This is so convenient!
