I consulted the technicians of FS. They helped me solve some technical problems about my new project as I posted my topology，and instructed me to go for the right products.

I tested the IL and it was as stated in the datasheet. A trustworthy brand.

This plc splitter module was shipped quickly and I had no problems with my order.

Order filled, shipped and received in timely manner.

So far so good. Item was packaged very well.

Though the shipping cost is a little higher, but the overall cost is the cheapest among my all suppliers. The 19" rack mount metal box seems to be made of good material and the design is userfriendly that can easily be installed in a 19″ ODF, insertion loss as expected.
