10 gigabit standard pdf

Continue Ethernet's 10 (10GBE or 10 GigE) ethernet standard with ports and three types of 10 Gigabit Ethernet (10GE, 10GbE or 10 GigE) modules represents 10 computer network technologies for Ethernet personnel transmission at 10 gigabits per second. It was first defined by IEEE 802.3ae-2002. Unlike previous Ethernet standards, 10 Gigabit Ethernet defines only a full duplex current to the point of reference, which is usually linked by network switches; CSMA/CD co-operation has not been moved from previous generations of Ethernet standards, so semi-deplex hubs and repeaters do not exist in 10GbE. Standard 10 Gigabit Ethernet includes a number of different physical layer standards (PHY). A network device, such as a switch or a network interface controller, can have different types of PHY through connected PHY modules, such as SFP-based. Like previous versions of Ethernet, 10GbE can use copper or fiber optic cables. The maximum distance over the copper cable is 100 meters, but due to its bandwidth requirements, more expensive cables are required. The adoption of 10 Gigabit Ethernet was more gradual than previous Ethernet changes: 1 million 10gbE ports were shipped in 2007, two million ports were shipped in 2009, and more than three million ports were shipped in 2010, with approximately nine million ports in 2011. As of 2012, although the price for a gigabit bandwidth of 10 Gigabit Ethernet was about one-third compared to Gigabit Ethernet, the price for port 10 Gigabit Ethernet still hindered wider adoption. Standards Over the years, the working group of the Institute of Electrical and Electronics Engineers (IEEE) 802.3 has published several standards relating to 10GbE.

PHY modules are not listed in the official standards authority, but in multi-source agreements (IAS) that can be agreed upon more quickly. Appropriate MSAs for 10GbE include XENPAK (and related X2 and XPAK), XFP and SFP. When choosing a PHY module, the designer takes into account cost, coverage, type of multimedia, energy consumption and size (form factor). A single current to a point link can have different MSA plug-in formats at both ends (such as XPAK and SFP) as long as a 10GbE optical or copper port type (such as 10GBASE-SR) is supported by a plug-in identical. XENPAK was the first MSA for 10GE and had the largest form factor. X2 and XPAK later competed with lower form factors. X2 and XPAK have not been as successful in the market as XENPAK. XFP came after X2 and XPAK, and it's also smaller. The newest standard of the module is an improved small form factor connected to a transiver, commonly called SFP. Based on a small form factor connected by a (SFP) and developed by the ANSI T11 fiber optic channel group, it is even smaller and less power than the XFP. The SFPC has become the most popular connector on 10GE systems. SFP modules only make optical for electrical conversion, without hours and data recovery, which puts a higher load on the leveling of the host channel. SFP modules have a common physical form factor with outdated SFP modules, allowing for higher port density than XFP, and reusing existing designs for 24 or 48 ports in a 19-inch blade-wide rack. Optical modules are connected to the host interface by XAUI, XFI or SerDes Framer Interface (SFI). XENPAK, X2 and XPAK modules use XAUI to connect to hosts. XAUI (XGXS) uses a four-lane data channel and is listed in IEEE 802.3 Item 47. XFP modules use the XFI interface, and SFP modules use the SFI interface. XFI and SFI use the single-band data channel and coding 64b/66b specified in IEEE 802.3 Item 49. SFP modules can be further grouped into two types of host interfaces: linear or restrictive. Restrictive modules are preferred, except when 10GBASE-LRM modules are used for long applications.

Yellow cables are a single mode of duplex fiber optic connections. There are two main types of optical fiber used for 10 Gigabit Ethernet: single-laundering (SMF) and multi-mode (MMF). In THE SMF, light follows one path through fiber, while in MMF it takes several paths, resulting in a differential mode (DMD) delay. SMF is used for long-distance communication, and MMF is used at distances of less than 300 m. SMF has a narrower core (8.3 microns), which requires a more accurate method of cessation and connection. MMF has a wider core (50 or 62.5 microns). The advantage of MMF is that it can be controlled by an inexpensive vertical cavity laser (VCSEL) over short distances, and multi-stage connectors are cheaper and easier to safely stop in the field. The advantage of SMF is that it can run long distances. The 802.3 standard mentions FDDI MMF fiber. It has a core of 62.5 microns and a minimum fashion bandwidth of 160 MHz and 850 Nm. It was originally installed in the early 1990s for PIDI and 100BASE-FX networks. Standard 802.3 also refers to ISO/IEC 11801, which lists optical types of MMF OM1, OM2, OM3 and OM4 fibers. THE OM1 has a core of 62.5 microns, while the rest have a core of 50 microns. At 850 Nm the minimum modal bandwidth of OM1 is 200 MHz km, OM2 500 MHz km, OM3 2000 MHz and OM4 4700 MHz km. FDDI cable is currently obsolete, and new structured cable installations use either OM3 or OM4. The OM3 cable can carry 10 Gigabit Ethernet 300 meters using inexpensive 10GBASE-SR optics. The OM4 can control 400 meters. To distinguish SMF from MMF cables, SMF cables are usually yellow, while MMF orange cables (OM1 and OM2) or aqua (OM3 and OM4). However, fiber optics do not have a single color for any particular optical speed or technology, except for the angular physical connector (APC), it is a consistent green color. There are also active optical cables (AOC). They have optical electronics already connected eliminating connectors between the cable and the . They are connected to standard SFP outlets. They are more cost-effective than other optical solutions because the manufacturer can match electronics with the required length and type of cable. 10GBASE-SR A 10GBASE-SR SFP- transceiver 10GBASE-SR (short range) is a port type for multi-stage fiber and uses 850 nm lasers. Its physical encoding sublayer (PCS) is 64b/66b and is defined in IEEE 802.3 Item 49 and its physical medium-dependent (PMD) sublayer in paragraph 52. He serial data at the line speed of 10.3125 Gbd. The range (m) FDDI-class (62.5) 25 OM1 (62.5) 33 OM2 (50) 82 OM3 300 OM4 400 MMF has an advantage over SMF having lower connector costs; its wider core requires less mechanical accuracy. The 10GBASE-SR transmitter is implemented with VCSEL, which is low cost and low power. OM3 and OM4 optical cables are sometimes described as laser optimized because they were designed to work with VCSELs. 10GBASE-SR provides the lowest cost, lowest power and lowest form factor optical modules. There is a lower cost, lower power option sometimes referred to as 10GBASE-SRL (10GBASE-SR Lite). It is an inter-opable with 10GBASE-SR, but only has a reach of 100 meters. The 10GBASE-LR 10GBASE-LR (long reach) is a port type for a single fiber mode and uses 1,310 nm of lasers. Its 64b/66b PCS is defined in IEEE 802.3 Item 49 and its PMD sublayer in paragraph 52. It delivers serial data at a line speed of 10.3125 GBd. DFB lasers are more expensive than VCSELs, but their high power and long wavelength allow for an effective connection to a small core of a single fiber mode over long distances. The maximum length of the 10GBASE-LR fiber is 10 kilometers, although this will vary depending on the type of mode used. The 10GBASE-LRM 10GBASE-LRM, (long multi-profile mode) originally listed in IEEE 802.3aq, is a port-type for multi-profile fiber and uses 1310 nm lasers. Its 64b/66b PCS is defined in IEEE 802.3 Item 49 and its PMD sublayer in paragraph 68. It delivers serial data at a line speed of 10.3125 GBd. 10GBASE-LRM allows distances of up to 220 meters (720 feet) on FDDI-class multi-mode fiber and the same 220m maximum coverage on OM1, OM2 and OM3 fiber types. Coverage of 10GBASE-LRM is not as far away as the old standard 10GBASE-LX4. Some 10GBASE-LRM also allow distances of up to 300 meters (980 feet) on standard single-mode fibers (SMF, G.652), however this is not part of the IEEE or MSA specification. To ensure that the specifications are made on FDDI, OM1 and OM2 fibers, the transmitter must be connected through the air conditioning mode patch cord. No air conditioning cord mode is required for applications over OM3 or OM4. 10GBASE-ER 10GBASE-ER (advanced coverage) is a port type for a single fiber mode and uses 1550 nm of lasers. Its 64b/66b PCS is defined in IEEE 802.3 Item 49 and its PMD sublayer in paragraph 52. It delivers serial data at a speed of 10.3125 GBd. 10GBASE-ER has a length of 40 km (25 miles) over engineering links and 30 km above standard links. Several manufacturers have introduced an 80 km (50 miles) range called This 80-kilometre PHY is not listed in the IEEE 802.3ae standard, and manufacturers have created their own specifications based on the 80 km PHY described in the OC-192/STM-64 SDH/SONET specifications. The 10GBASE-LX4 10GBASE-LX4 is a port type for multi-stage fiber and single mode. It uses four separate laser sources running at 3.125 Gbit/s and a rough wavelength of multiplexing division with four unique wavelengths of about 1,310 nm. Its 8B10B PCS is defined in IEEE 802.3 Item 48 and its physical average dependent (PMD) underlay in paragraph 53. The 10GBASE-LX4 has a range of 10 km over the SMF. It can reach 300 meters (980 feet) above FDDI-class, OM1, OM2 and OM3 multi-stage cables. In this case, it should be connected through the SMF shift launch mode air conditioning patch cord. Subclause 53.6 and 38.11.4 10GBASE-PR 10GBASE-PR, originally listed in IEEE 802.3av, are 10G Ethernet PHY for passive optical networks and use 1577 nm lasers in the direction of downstream and 1270 nm lasers in the direction upstream. Its PMD is listed in paragraph 75. Downstream provides serialized data at a line speed of 10.3125 Gbit/s at a point to multi-point configuration points. 10GBASE-PR has three power budgets listed as 10GBASE-PR10, 10GBASE-PR20 and 10GBASE-PR30. 23: 75.1.4 Two-point single-point one- strand Multiple vendors have introduced one strand, a 10 Gbit/s dual-direction optic optician capable of single-temperature fiber optic communication, functionally equivalent to 10GBASE-LR or -LR, but using one strand of fiber optic cable. Similar to the 1000BASE-BX10, this is achieved by using a passive prism inside each optical transceiver and a comparable pair of transceivers using two different wavelengths such as 1270 and 1330 nm. The modules are available in a variety of transmission powers and ranges from 10 to 80 km. 10GBASE-CX4 SFF-8470 connector 10GBASE-CX4 was the first 10G copper standard published 802.3 (as 802.3ac-2004). It uses a four-lane PCS XAUI (Clause 48) and copper cables similar to those used by InfiniBand technology. It is specified that the work is up to 15 m (49 feet). Each lane has a 3.125 GBd signal bandwidth. The 10GBASE-CX4 offers the benefits of low power, low cost and low latency, but has a larger form factor and more bulky cables than the newer SFP standard and much shorter coverage than fiber or 10GBASE-T. This cable is quite rigid and significantly more expensive than category 5 or 6 UTP. Deliveries of 10GBASE-CX4 today are very low. Although some network providers offer CX-4 interfaces that can be used for 10GBASE Ethernet or for stacking switches at (slightly) lower latency. Some examples of combi styling/ Ethernet are Dell PowerConnect PCT6200, and 1G Powerconnect Powerconnect PCM6220 and PCM6348 switches. Direct adherence to SFP's Logical LE3442-CU SFP dual NIC port, which can use SFP- DAC cables or SFP optical transceivers, also known as Direct Attach (DA), Direct Attach Copper (DAC), 10GSFP-Cu, 10GBASE-CR, 10GFPBASE-CX1, S, or 10GbEP. Direct Attach short cables use passive two-axis cable assembly, while longer ones, sometimes called active optical cable (AOC), use short long optics. Both types are connected directly to the SFP case. SFP' direct connection has a fixed length cable, usually 1 to 7 m (passive cables), up to 15 m (active cables), or up to 100 m in length (active optical cables). Like the 10GBASE-CX4, the DA is low power, low cost and low latency with the added benefits of using smaller cables and having a small SFP form factor. SFP's direct accession is extremely popular today, with more ports installed than 10GBASE-SR. Backplane Backplane Ethernet, also known as Target Group 802.3ap, is used in backplane applications such as blade servers and modular routers/switches with updated linear maps. 802.3ap implementations are required to operate in an environment consisting of up to 1 meter (39 inches) of copper circuit board with two connectors. The standard defines two port types for 10 Gbit/s (10GBASE-KX4 and 10GBASE-KR) and 1 Gbit/s port type (1000BASE-KX). It also identifies an extra layer for the FEC, a backplane autogodation protocol and a training link for the 10GBASE-KR, where the receiver can set the equalizer of the transfer of three taps. The auto-preparation protocol chooses between 1000BASE-KX, 10GBASE-KX4, 10GBASE-KR or 40GBASE-KR4 operation. 40GBASE-KR4 is defined at 802.3ba. The new backplane designs use 10GBASE-KR, not 10GBASE-KX4. 10GBASE-KX4 It works on four backplane lanes and uses the same physical coding layer (defined in IEEE 802.3 Item 48) as 10GBASE-CX4. 10GBASE-KR This works on one jet rear strip and uses the same physical coding layer (defined in IEEE 802.3 Item 49) as 10GBASE-LR/ER/SR. The 10GBASE-T Intel X540-T2 10GBASE-T dual port NIC 10GBASE-T, or IEEE 802.3an-2006, is a standard issued in 2006 to provide 10 Gbit/s connections over non-green or screened twisted cable pairs, at distances of up to 100 meters (330 feet). Category 6a must reach a full distance of 100 meters (330 feet) and Category 6 can reach a distance of 55 meters (180 feet) depending on the quality of the installation, determined only after retesting up to 500 MHz. 10GBASE-T cable infrastructure can also be used for 1000BASE-T allows for a gradual upgrade from 1000BASE-T using autonation to choose which Use. Due to the additional overhead coding lines, 10GBASE-T has a slightly higher latency compared to most other 10GBASE variants, ranging from 2 to 4 microseconds compared to 1 to 12 microseconds per 1000BASE-T 1000BASE-T (depending on the size of the package). As of 2010, 10GBASE-T silicon is available from several manufacturers with a stated 3-4 watt power dissipation at a 40 nm structure size, and with 28 nm in development, capacity will continue to decline. 10GBASE-T uses modular IEC 60603-7 8P8C connectors already widely used with Ethernet. Transmission characteristics are now shown to be up to 500 MHz. To achieve this category 6A frequency or better balanced of cables, ISO/IEC 11801 Amendment 2 or ANSI/TIA-568-C.2 are required to carry 10GBASE-T at distances of 100 m. Category 6 cables can carry 10GBASE-T for shorter distances at qualifications in accordance with ISO TR 24750 or TIA-155-A guidelines. Standard 802.3an defines a 10GBASE-T wire level modulation for the use of pre-encoding tomlinson-Harashima (THP) and modulation of pulse amplitude with 16 discrete levels (PAM-16) encoded in a two-dimensional chessboard pattern known as DS128 sent to the 800 Msymbols/sec line. with the design of a parity verification matrix based on the generalized Reed-Solomon code (32,2,31) over GF (26). Another 1,536 bits are not encoded. In each block 1723-1536, there are 1'50'8'1 alarms and bug detection bits and 3,200 bits of data (and occupying 320 ns on the line). Unlike the PAM-5 is the modulation method used in the 1000BASE-T Gigabit Ethernet. The 10GBASE-T SFP' transciver coding line used by 10GBASE-T is the basis for the new and slower 2.5GBASE-T and 5GBASE-T standard, implementing a 2.5 or 5.0 Gbit/s connection over the existing category 5e or 6 cables. Cables that will not function reliably with 10GBASE-T can successfully operate with 2.5GBASE-T or 5GBASE-T with support from both ends. 10GBASE-T1 10GBASE-T1 for automotive applications and is working on one balanced pair of conductors. WAN PHY (10GBASE-W) At the time when standard 10 Gigabit Ethernet was developed, interest in 10GbE as a broad network (WAN) transport led to the introduction of WAN PHY for 10GbE. WAN PHY encapsulates Ethernet packages in SONET OC-192c frames and operates at a slightly lower data rate (9.95328 Gbit/s) than localized network (LAN) PHY. WAN PHY uses the same optical PMG 10GBASE-S, 10GBASE-L and 10GBASE-E optical PMG as LAN PHY, and is labeled as 10GBASE-SW, 10GBASE-LW or 10GBASE-EW. Its 64b/66b PCS is defined in IEEE 802.3 Item 49 and its PMD sublayer at paragraphs 52. It also uses the Wan Sublayer Interface (WIS) defined in paragraph 50, which adds additional encapsulation to format frame data to be compatible with SONET STS-192c. WAN PHY can travel a maximum connection distance of up to 80 km depending on the fiber standard used. Notes : Category 6 cable support runs up to 55 meters. Category 6A or higher is good for length up to 100 meters. All of these types of fibers are specified to have a minimum fashion bandwidth of 500 MHz × km at 1300 Nm. The maximum Gigabit Ethernet package requires 12.2 microns for transmission (1526 × 8 ÷ 109) for store and forward, this adds to the hardware delay.

The History Industry Consortium, a consortium of 25G Ethernet, was formed by Arista, Broadcom, Google, Mellanox Technologies and Microsoft in July 2014 to support the specification of 25-Gbit/s Ethernet single-band technology and 50 Gbit/s Ethernet dualband technology. The 25G Ethernet consortium specification project was completed in September 2015 and uses technology from IEEE Std. 802.3ba and IEEE Std. 802.3bj. In November 2014, the IEEE 802.3 task force was formed to develop the 25 Gbit/s single-band standard, and in November 2015 a training group was established to study the development of the single-band 50-Gbit/s standard. On June 30, 2016, IEEE 802.3by was approved by the IEEE-SA Standards Board. On November 12, 2018, the IEEE P802.3cn Task Force began work on PHY supporting 50 Gbit/s for at least 40 km of SMF. The IEEE 802.3cd standard was approved on December 5, 2018. On December 20, 2019, IEEE 802.3cn was published. On April 6, 2020, the consortium rebranded the Ethernet Technology Consortium and announced the specification of 800 Gigabit Ethernet (GbE). On June 4, 2020, IEEE approved IEEE 802.3ca, allowing symmetrical or asymmetrical work at a speed downstream of 25 Gbps or 50 Gbps, as well as speeds upstream of 10 Gbps, 25 Gbps, or 50 Gbps over passive optical networks. The 25 Gigabit Ethernet Standard IEEE 802.3by uses technology defined for , implemented as four 25 Gbit/s bands (IEEE 802.3bj). The IEEE 802.3by is standard for several single-lane variations. 25GBASE-T, the 25 Gbit/s standard for twisted pair, was approved along with 40GBASE-T as part of IEEE 802.3bq.

Невозможно передать 53.125 Gbit/s по электрическому интерфейсу, сохраняя при этом подходящую целостность сигнала, поэтому четырехуровневая модуляция амплитуды импульса (PAM4) используется для картирования пар битов в один символ. Это приводит к общей ставке 26,5625 GBd для 50 Gbit/s за полосу Ethernet. Кодирование PAM4 для 50G Ethernet определено в пункте 135 стандарта 802.3.
