This is certainly true of the electrical interface between transceiver and transceiver port. However, the client side interface is standard CX4, so any CX4 device should work fine, including XFP CX4 (which - unlike most XFPs - will contain a serdes). Nick

Not objecting to the characterization of the existance of xfp/cx4 connections, only clarifying what such a device does.
