The CoaXPress-over-Fiber Host Bridge IP Core allows to connect a CoaXPress Host IP Core to an nGMII (10/25 Gbps Media Independent Interface) bus inside an FPGA. nGMII, as defined in IEEE Std 802.3 Clause 46, is the main access to the 10/25G Ethernet physical layer. The generic nature of this interface facilitates mapping the CoaXPress signaling into the PCS/PMA Ethernet sublayers. The IP converts nGMII packets received from an Ethernet PCS/PMA block, back to CoaXPress packets.

CoaXPress-over-Fiber is a light but significant extension of the existing CoaXPress specification to support transport over fiber optics.

CoaXPress (CXP) is the de-facto standard for high-bandwidth computer vision applications. CoaXPress 2.1, the latest version of the specification, specifies the CXP-12 speed, a 12.5 Gbps (Gigabit per second) connection over a coaxial copper cable. As link aggregation is common with CoaXPress, bandwidths of 50 Gbps (12.5 x 4) are easily achievable with four CXP-12 connections. CoaXPress-over-Fiber has been designed as an add-on to the CoaXPress specification. It provides a way to run the CoaXPress protocol, as it is, unmodified, over a standard Ethernet connection, including fiber optics. As such, CoaXPress-over-Fiber uses standard electronics, connectors and cables designed for Ethernet, but the protocol is CoaXPress, not Ethernet, not GigE Vision.
