I am writing to you to confirm that I received the first package (with everything except the NIC).
I can confirm that these 10km transceivers are working well, even with the 20m cables! They are a bit overkill and expensive, but due to the limited boring diameter we can afford, they will be much better for us than duplex transceivers.

The transceiver came in good condition. It worked as expected, no issues, truly a quality product. If I need more, I will definitely come back.

I purchased this module from FS, which is very helpful for my 5G application needs. Quality of your products & your support is very good.
