Even when our market seeks OTN from European backhaul providers to extend submarine access into Europe and Asia-Pac, it is often for structured capacity grooming, and not for OAM benefit.
It would be interesting to learn whether other markets in the world still make a preference for OTN in lieu of Ethernet, for the OAM benefit, en masse. When I worked in Malaysia back in the day (2007 - 2012), WAN-PHY was generally asked for for 10G services, until about 2010; when folk started to choose LAN-PHY. The reason, back then, was to get that extra 1% of pipe bandwidth :-).
Oh I don't think OTN or WAN-PHY have any large deployment future, the cheapest option is 'good enough' and whatever value you could extract from OTN or WAN-PHY, will be difficult to capitalise, people usually don't even capitalise the capabilities they already pay for in the cheaper technologies. Of course WAN-PHY is dead post 10GE, a big reason for it to exist was very old optical systems which simply could not regenerate ethernet framing, not any features or functional benefits. -- ++ytti
