Cogent Communications has more Ethernet ports in service throughout the United States than any other service provider, according to research and analysis firm Ovum-RHK. But in terms of Ethernet revenue, Cogent ranked third.

Though the number of Cogent Ethernet ports in service is unknown, a company spokesman said it is “almost” equal to the number of customers Cogent has in the U.S.: 8700.

Cogent, whose primary Ethernet service is a 100 Mb/s commercial Internet access service for $1000 per month, reported net service revenue of more than $15 million in North America and more than $5 million in Europe for the first quarter of 2005.
