What is a XAUI interface?

What is a XAUI interface?

10Gb Ethernet Attachment Unit Interface or XAUI is a high-speed interconnect that offers reduced pin count and has the ability to drive up to 20 inches of PCB trace on standard FR-4 material.

What is Xgmii?

10 gigabit media-independent interface (XGMII) is a standard defined in IEEE 802.3 designed for connecting full duplex 10 Gigabit Ethernet (10GbE) ports to each other and to other electronic devices on a printed circuit board (PCB). It is now typically used for on-chip connections.

What is Sgmii interface?

The serial gigabit media-independent interface (SGMII) is the interface with the lowest pin count available for connecting compatible MACs and PHYs. It consists of pairs of Txdata, Rxdata, and Rx Ref Clk data pins.

What is dual GB Ethernet?

Bonding Dual Gigabit Ethernet This enables your computers to view them as a single interface, using one gigabit connection to send and the other to receive. This arrangement effectively doubles your input to 2 Gbps if you’re using gigabit cards, or 20 Gbps if you’re using 10 GB cards.

What is difference between SFP and XFP?

The most suggested way of transmitting data is to use light-based fiber optics. “XFP” stands for “10 Gigabit Small Form Factor Pluggable” while “SFP” stands for “Small Form-factor Pluggable.” Both modules can provide you greater signal strength in your computer network, and telecommunication links.

What is xFi and SFI?

XFI, SFI and KR are all 10Gbps serial high-speed electrical interfaces, intended to allow transmission of 64B/66B encoded data in networking systems . XFI and SFI electrical specifications respectively apply to XFP and SFP+ system front port optical modules. These specs were defined by the SFF MSA industry group.

What is PHY interface?

A PHY, an abbreviation for “physical layer”, is an electronic circuit, usually implemented as an integrated circuit, required to implement physical layer functions of the OSI model in a network interface controller.

What is the difference between SGMII and SerDes?

SGMII performs the same task, extended to include gigabit Ethernet, although it can be used for 10/100 Mbit/s TX/RX as well. SerDes technology, which is often used with SGMII, provides LVDS (low-voltage differential signaling) for converting between serial and parallel signal routing, as shown in the figure below.

What is LAN PHY and WAN PHY?

lan-phy —10GBASE-R interface framing format that bypasses the WIS sublayer to directly stream block-encoded Ethernet frames on a 10-Gigabit Ethernet serial interface. wan-phy —10GBASE-W interface framing format that allows 10-Gigabit Ethernet wide area links to use fiber-optic cables and SONET devices.

What is PHY in WIFI?

Phy Rate (physical rate) is the speed at which the bits are actually sent. For example, in a fast network your Phy rate could be 800Mbps (e.g. 802.11ac 2×2). On a slower network the Phy rate could be much lower, e.g. 65Mbps (e.g. 802.11n 1×1).

What is PHY for Internet?

A PHY connects a link layer device (often called MAC as an acronym for medium access control) to a physical medium such as an optical fiber or copper cable. A PHY device typically includes both physical coding sublayer (PCS) and physical medium dependent (PMD) layer functionality.

What does Ethernet PHY do?

An Ethernet PHY is designed to provide error-free transmission over a variety of media to reach distances that exceed 100m. The Ethernet PHY is connected to a media access controller (MAC). The MAC is usually integrated into a processor, FPGA or ASIC and controls the data-link-layer portion of the OSI model.
