CoaXPress-Over-Fiber HOST IP

CoaXPress-Over-Fiber HOST IP

• Compliant with CoaXPress over Fiber Bridge Protocol V1.0 (released 2021)

• Supports up to CXP‑12 downlink high-speed link, 41.6 Mbps uplink low-speed link; nGMII complies with IEEE Std 802.3 Clause 46

• nGMII supports 10G/25G options, default is 10G

• Uses FPGA built-in high-speed transceivers as the PHY, easy to use

• No complex configuration required; simply instantiate the IP and make basic connections

CoaXPress-over-Fiber (CoF)

CoaXPress-over-Fiber is an important extension of the existing CoaXPress specification, designed to enable transmission over optical fiber.

CoaXPress-over-Fiber is defined as an add-on to the CoaXPress 2.0 specification. It allows running the unmodified CoaXPress protocol over standard Ethernet connections, including optical fiber.

Although CoaXPress-over-Fiber uses standard Ethernet electronics, connectors and cables, the protocol it carries is CoaXPress — not Ethernet, nor GigE Vision.

In short, CoaXPress-over-Fiber lets you reuse existing Ethernet infrastructure, especially optical fiber networks, to transport CoaXPress protocol data without any changes to the protocol itself.

This expands CoaXPress into a wider range of applications, particularly those requiring long distances or higher bandwidth.
