CoaXPress-over-Fiber is a light but significant extension of the existing CoaXPress specification to support transport over fiber optics.
By using fiber optics connectivity, CoaXPress-over-Fiber benefits from the almost unlimited cable lengths and reduced cable congestion (fiber optics are lighter and thinner than coaxial cables). By leveraging Ethernet Physical Layer standards (IEEE 802.3), CoaXPress-over-Fiber also benefits from the low-cost standard components (such as connectors and cables) and their constant evolution towards higher bandwidths.
Most importantly, CoaXPress-over-Fiber allows CoaXPress to go beyond the physical limitations of coaxial cables in terms of bitrate.
