I’m not sure if I can use west or east, or west and east. Powerful FS guys asked about our system info, and shows us the differences of the two transmission directions. We finally go with the option of west and east.

The item successfully added new waves into our CWDM system. And another item I wanted to recommend was the FMU rack chassis. Installed the OADM in the chassis, both the two perfectly lied on our cabinet.

I was looking for a dual fiber CWDM OADM that could be used in our company’s CWDM system, and FS answered they could customize it for me after a few emails. It wasn’t a long time before I received the OADM in a solid package. Good job!

We replaced two old CWDM OADMs with these new ones because our clients were about to increase in a week. The well-customized products and the client increase are both pleasing for us. We expect more cooperations with FS in the near future.

Various choices for me to choose what I need. Item was delivered on time and exactly what I ordered.

Best people in FS.COM. My order was processed quickly and came intact.
