What is 10GBASE KX4?

The parallel version (10GBASE-KX4) is the general design of the backplane, it separates the 10 Gigabit signal into four lanes, like XAUI. 10GBASE-KX4 uses the same physical layer coding like 10GBASE-CX4; the bandwidth of every lane is 3.125 Gbps. In the serial version (10GBASE-KR), only one lane was defined.

What is XAUI interface?

The 10 Gigabit Attachment Unit Interface (XAUI) is an optional, self-managed interface that can be inserted between the reconciliation sublayer and the PHY layer to transparently extend the physical reach of the 10 Gigabit Media Independent Interface (XGMII). XAUI addresses several physical limitations of the XGMII.

What is 10gb Ethernet used for?

Enterprises use 10 Gigabit Ethernet switches to provide Layer 2 networking for very high-speed network applications – mostly in the data center or server room.

What is the difference between LAN PHY and WAN PHY?

The only difference between the LAN PHY and the WAN PHY is the WIS sublayer. Both share the same PCS and serial Physical Medium Attachment (PMA) and Physical Medium Dependent (PMD) sublayers. In this way, the cost benefit from economies of scale applies to both PHY types.

What is the speed of an XAUI interface?

The Xilinx 10 Gigabit Attachment Unit Interface (XAUI) LogiCORE™ IP provides a 4-lane high speed serial interface, providing up to 10 Gigabits per second (Gbps) total throughput.

Is it worth getting 10Gb Ethernet?

Currently, Gigabit Ethernet (1Gbit/s or 125MB/s) is more than fast enough for any application. That doesn’t mean that 10 Gigabit Ethernet is pointless. Thanks to higher internet speeds, more cloud services, and more intensive applications running on servers, computers are starting to use a lot more data.

What’s the difference between 10GBASE KX4 and 10 Gbase KR?

Even though both 10GBASE-KX4 and 10GBASE-KR are 10 Gbps electrical interfaces, they describe different PHYs. A 10GBASE-KX4 PHY operates at 1/4 rate of the 10GBASE-KR across 4 lanes to achieve the same throughput.

What does XAUI stand for in IEEE 802.3?

10 Gigabit Attachment Unit Interface ( XAUI / ˈzaʊi / ZOW-ee) is a standard for extending the XGMII (10 Gigabit Media Independent Interface) between the MAC and PHY layer of 10 Gigabit Ethernet (10GbE) defined in Clause 47 of the IEEE 802.3 standard.

Is the XGMII the same as the XAUI?

The XGMII is a 74 signal wide interface (32-bit data paths for each of transmit and receive) that may be used to attach the Ethernet MAC to its PHY. The XAUI may be used in place of, or to extend, the XGMII in chip-to-chip applications typical of most Ethernet MAC to PHY interconnects (See Figure 2).

What kind of cable does 10GBASE CX4 use?

However, the transmission distance is limited to 15 meters. 10GBASE-CX4 uses XAUI defined in the 802.3ae and 4X connector used in InfiniBand. The transmission media is called CX4 copper cable [ IEEE02 ]. 10GBASE-KX4 and 10GBASE-KR correspond to the IEEE 802.3ap standard published in 2007.
