LAN PHY dominates in the US too. Requests for WAN PHY were almost exclusively for terrestrial backhaul extending off of 
legacy subsea systems that still commonly had TDM-framed services. It’s been a couple of years since I’ve been in 
optical transport directly but these requests were essentially non-existent after 2018 or so. OTN became somewhat more 
common from 2014 onward as optical system interop improved, but actually was more common in the enterprise space as 
providers would generally go straight to fiber in most use cases, and with dark fiber opex costs coming down in many 
markets, I see OTN requests as winnowing here as well.
