CoaXPress-Over-Fiber HOST IP
Product Overview
CoaXPress-Over-Fiber (CoF) HOST IP is an easy-to-use, high-performance FPGA IP core that supports CoaXPress protocol transmission over standard fiber optics, compliant with CoaXPress over Fiber Bridge Protocol V1.0 (2021).
Without modifying the CoaXPress protocol itself, this IP allows reuse of existing Ethernet fiber infrastructure to transmit images and data, expanding long-distance, high-bandwidth application scenarios.
Key Features
- Compliant with CoaXPress over Fiber Bridge Protocol V1.0 (2021)
- Supports up to CXP-12 downlink high-speed link and 41.6 Mbps uplink low-speed link
- nGMII interface supports 10G/25G (default 10G), compliant with IEEE Std 802.3 Clause 46
- Uses FPGA built-in high-speed transceivers (GT) as PHY, no external chips required
- Easy to use: instantiate and connect simply, no complex configuration
- Supports all Xilinx FPGAs with GT high-speed transceivers
CoaXPress-over-Fiber Introduction
CoaXPress-over-Fiber is an important extension of the existing CoaXPress 2.0 specification, designed to transmit unmodified CoaXPress protocol over standard Ethernet and fiber.
Although it uses standard Ethernet hardware, connectors and cables, the protocol transmitted is CoaXPress, not Ethernet or GigE Vision.
In short, CoF allows users to reuse deployed fiber and Ethernet infrastructure to directly transmit CoaXPress images and data without changing the protocol.
