Centec is a mainland China silicon switch chip house that has been in business since 2005. They do their own chip designs, so not Broadcom. Because they are a small player, they go to the ODMs to get their switches built and not the other way 'round. They use ODMs like EmbedWay to make switches that are then sold under the Centec label.
