While options exist such as the Cisco 9500 series mentioned by Fredy, for 25 Gbps, I don't know that it has ever caught on for WAN purposes to find its way into carrier demarc equipment. as a common optio. Or as a service tier that major lit service last-mile providers are interested in providing their sales team as a standard product to sell.
The bulk of the equipment and use case I've seen for it is as a LAN top of rack switch for server/equipment aggregation, or similar, where it would have previously been a 48-port 10 Gbps SFP+ based switch in the same place in the past. Such as for very price sensitive 'enterprise' customers that have outgrown 10 Gbps but don't have the need or want to spend the money to go to 100 Gbps to every server.
