Thanks for FS designing a 48CH DWDM & OADM dual fiber system for our 45 site links. They suggested that we could use the 80km DWDM modules for the system, and they also helped us to control the RX power within -15~20dB to ensure the modules’ performance. For now, I haven’t had any packet lost.

I have customers who want to buy transceivers, but the transceivers need to be packed with electrostatic bag packaging. So I searched on internet but no one can meet our needs. Fortunately I found FS. At beginning, I noticed the package on their website are all plastic clamshell box packing, and I thought it would make me disappointed again. But I am so lucky that they can provide me with the electrostatic bag packaging, and fill the box with foam to avoid damage in delivery. Got to say FS.COM have superior service.

I changed my original supplier and choose FS. The quality of the transceivers they provide is really good. Fast transmission rate, long transmission distance and cheap price.
