At 3dB loss per split you'd very quickly need additional amplification, at which point the ROADM is cheaper. A static split can do the 80 waves in much less than the ~20dB a power split would need, and
ROADMs already solve this problem, and are available at the module level (how practically available and usable I've no idea, never needed to try).Compare the price of a ROADM and a 50%/50% light splitter. Which one do you think is the cheapest and also operationally most reliable?
Not disagreeing, I'd go with dumb static optics, nearly all the "reconfigurable" optic selling points don't seem to translate into actual operational benefits.
