More SFP converter in a network

Hi!

I would like to ask a question about a small factory network. I was learning networking 10 years ago, working on a cnc machine, and my boss asked me if this will works.

We would like to use 5 TP-Link MC220L.

We have 4 switches that does not have a SFP module.

If we buy 4 MC220L and we connect them with the switches, will it work? (let me try to explain)

Switch1 ethernet to MC220L(1) Ethernet

MC220L(1) SFP to MC220L(2) SFP

MC220L(2) Ethernet to Switch2

Switch2 ethernet to MC220L(3) ethernet

MC220L(3) SFP to MC220L(4) SFP

MC220L(4) Ethernet to Switch3

Switch3 ethernet to MC220L(5) ethernet

MC220L(5) SFP to MC220L(6) SFP

MC220L(6) SFP to Switch4

​

Or is this totally pointless.

We got optical internet some days ago, and the network is not builded yet. My boss wants to build the network cheap AF.

​

Thanks for the helping.
