... based on the DWDM technology.

It was new at that time.

And DWDM was very new.

So i- in fact-

Exactly

I'm selling at SFP at 400G waves.

So I saw the first SFP 10 gig at that time.

So how real is this shift and what's the timeline before we see a meaningful dent in that 90 plus import dependency on specialty materials?

So you know you are absolutely right like optical trans receivers are required in GPON and in DWDM or OTN and right from 1 gig for the fiber to the home up to the 100 gig we were importing all those optical trans receivers and with clean rooms coming up with the backward integration happening in India with BOSA technology.

I think we will create that ecosystem very soon.

So to answer your question, I expect at least next two years to really have these ECMS companies to go into full production with their capital equipment installation, commissioning, and manufacturing setup.
