Embodiment Construction

[0040] Various embodiments of the invention are discussed in detail below. It should be understood that, while specific embodiments are discussed, this is done for purposes of illustration only. A person skilled in the art will appreciate that other components and configurations may be used without departing from the spirit and scope of the invention.

[0041] Ethernet has become an increasingly popular technology used in a variety of environments including twisted pair, backplane and fiber optic applications. The inherent simplicity of Ethernet allows the technology to be used across a variety of media, speeds, and distances. These characteristics make Ethernet a viable technology choice across high-speed laboratory networks, business networks, and even customer networks.

[0042] As Ethernet becomes more popular, its economies of scale are becoming more and more attractive. Therefore, obtaining a simple, low-cost Ethernet solution is an important factor in facilitating th...

Abstract

A system and method for frequency division multiplexed high speed physical layer devices. A next generation Ethernet device can be generated through reuse of existing architectures. Multiple instantiations of an existing architecture can be supported on a given wire pair by frequency division multiplexing on a number of carriers. The multiple instantiations can enable multiple modes that can support different configurations, variable rates, and energy efficient Ethernet.

Description

technical field [0001] The present invention relates to Ethernet systems and methods. More specifically, the present invention relates to methods and systems for use in frequency division multiplexing high-speed physical layer devices. Background technique [0002] As standardized transmission rates increase by orders of magnitude, the capabilities of Ethernet devices increase. In a relatively short period of time, the transmission rate of standardized Ethernet equipment has increased from 10Mbit / s to 100Mbit / s, from 100Mbit / s to 1Gbit / s, and even recently from 1Gbit / s to 10Gbit / s. Efforts are currently underway to determine the next transmission rate that will be the next standard for Ethernet performance. Whether it is 40Gbit / s or 100Gbit / s, the next transmission rate will be much higher than 10Gbit / s. [0003] The dramatic increase in standardized transmission rates has provided a huge boost to the increase in available bandwidth in Ethernet. The dramatic increase in ...
