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 10GBASE Kr?

For example, 10GBASE-KR is a 10 Gbps (10G) data rate baseband (BASE) specification, with a backplane (K) medium, using a 64B/66B (R) coding scheme, in a single lane configuration. This is purely an electrical specification that fully defines the features and characteristics of a compliant Ethernet PHY.

What is XGMII interface?

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).

What is XFI interface?

XFI. The XFI electrical interface specification is a 10 gigabit per second chip-to-chip electrical interface specification defined as part of the XFP multi-source agreement. It was also developed by the XFP MSA group. XFI is sometimes pronounced as “X” “F” “I” and other times as “ziffie”.

What does an 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.

What is MII and RMII?

MII vs RMII for Ethernet Therefore, RMII (reduced MII) was developed as a variant of MII to cut the number of unshareable signals per PHY interface in half (down to 8 per PHY). The RMII specification is also capable of supporting 10 Mbps and 100 Mbps data rates, and there are gigabit-capable variants.

What is Sgmii used for?

The Serial Gigabit Media Independent Interface (SGMII) is a connection bus for Ethernet Media Access Controllers (MACs) and Physical Layer Devices (PHYs) defined by Cisco Systems. It replaces the classic 22-wire GMII connection with a low pin count, 4-pair, differential SGMII connection.

What is XFP and SFP?

“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 an SFP+?

The SFP+ (enhanced small form-factor pluggable) is an enhanced version of the SFP that supports data rates up to 16 Gbit/s. The SFP+ specification was first published on May 9, 2006, and version 4.1 published on July 6, 2009.

What are PHY switches?

A physical network switch is a hardware device used to connect devices and enable communication across a network. The physical network port of the hardware device is usually physically linked to an associated port at the switch.
