What is Ethernet backplane?
Ethernet operation over electrical backplanes, also referred to as “Backplane Ethernet,” combines the IEEE 802.3 Media Access Control (MAC) and MAC Control sublayers with a family of Physical Layers defined to support operation over a modular chassis backplane.
What is Gigabit Ethernet PHY?
Texas Instruments DP83867 Gigabit Ethernet PHY is a robust, low power, fully featured Physical Layer transceiver with integrated PMD sublayers to support 10BASE-T, 100BASE-TX and 1000BASE-T Ethernet protocols. The DP83867 is designed for easy implementation of 10/100/1000 Mb/s Ethernet LANs.
What is 10g LAN PHY?
10 Gigabit Ethernet (10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard.
What is XAUI interface?
XAUI, the 10 Gigabit Attachment Unit Interface, is a technical innovation that dramatically improves and simplifies the routing of electrical interconnections. Developed by the IEEE 802.3ae 10 Gigabit Ethernet Task Force, XAUI delivers 10 Gb/s of data throughput using four differential signal pairs in each direction.
What is a backplane medium?
A backplane is the circuitry that provides connectivity between the different modules on a switching or routing device. The data bus those three modules are plugged into is the backplane: it provides the connectivity between the modules.
What is backplane bus?
A backplane (or “backplane system”) is a group of electrical connectors in parallel with each other, so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a computer bus. A backplane uses plug-in cards for storage and processing.
Why is Ethernet PHY needed?
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 Ethernet PHY transceiver?
An Industrial Ethernet PHY is a physical layer transceiver device for sending and receiving Ethernet frames based on the OSI network model. In the OSI model, Ethernet covers Layer 1 (the physical layer) and part of Layer 2 (the data link layer) and is defined by the IEEE 802.3 standard.
What is the difference between WAN PHY and LAN 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 maximum distance of 10GBASE-SR?
10 Gigabit Fiber
| Standard | Media | distance |
|---|---|---|
| 10GBASE-SR | 62.5µm MMF | 26m-82m |
| 10GBASE-LRM | 62.5µm MMF | 220m |
| 10GBASE-LX4 | 62.5µm MMF | 300m |
| 10GBASE-SR | 50µm OM3 | 300m |
What are XAUI ports?
From Wikipedia, the free encyclopedia. 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.
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.
Why do we need a backplane for Ethernet?
Relatively new “backplane” Ethernet standards enable high-speed links over PCBs, through connectors and backplanes. These link standards provide a number of advantages for modular embedded systems that connect together multiple processor cards, in particular modern high-performance embedded computing (HPEC) systems based on the VPX standard.
What kind of Ethernet is used in 802.3ap?
Backplane Ethernet was included in the 802.3ap. The benefits of initial Serializer/Deserializer (SerDes) Ethernet are offered by 1000BASE-KX. For example, Gigabit performance over two differential pairs across electrical backplanes [ McCoubrey16 ].
Is the 88×5113 a single port or quad port Ethernet?
The device operates as a single port 100 Gbps Ethernet PHY/Quad port 25 Gbps Ethernet PHY. In this mode, the 88X5113 100 GbE and 25 GbE transmission over a variety of media including optics, passive copper cables and backplanes. The 88X5113 has long reach SERDES, and includes Auto-Negotiation and coefficient training functionality.
What is the capacity of a backplane switch?
Backplane capacity acts as a cap on the maximum throughput of a network device. Using our 24 port switch example above, suppose each port offers 1Gbps (Gigabit per second) speed, and the backplane capacity is 10Gbps.
