We have few different campuses, currently done like in the upper part of the pic. Switches are connected to switches and to other switches etc. So if one fails, a lot switches behind that switch fail too. (Some buildings have more layers but I was lazy with paint...)
As we don't have enough fibers from distribution switch to all access switches, I was thinking of getting CWDM MUXes and chaining them, and dropping some wavelengths on the way to switches. And hopefully in the end all the access switches are logically connected to the distribution switch by just one wavelength.
Would this work? Do I need amplifiers anywhere (all the switches are withing few kilometers)? Any other thoughts? Would be something from fs.com....
Thanks!
