Ethernet Network Standards

14. 10 Gigabit Ethernet

10 Gigabit Ethernet - or 10GB - sometimes referred to as 10GbE can achieve speeds of 10 Gbps, which is ten times faster than Gigabit Ethernet. It is often used in LAN backbones. Many 10 Gigabit Ethernets use multimode fiber as a transmission medium. This type of fiber, which is able to transmit multiple modes of light simultaneously, provides low data-loss connections and can be powered by low-cost optical sources, making it a cost effective option. Gigabit Ethernet can also single mode fiber to connect devices over longer distances Two 10GBase standards - 10GBase-T and 10GBase-CX4 - use copper cables to transmit data. The 10GBase-T standard uses UTP cables, which can transmit data for distances up to 100 meters, or about 109 yards. The 10GBase-CX4 standard uses four thin twin-axial cables which can transmit data for up to 25 meters, or about 27 yards.14. 10 Gigabit Ethernet 10 Gigabit Ethernet - or 10GB - sometimes referred to as 10GbE can achieve speeds of 10 Gbps, which is ten times faster than Gigabit Ethernet.

5. American National Standards Institute (ANSI)

ANSI is the national standards institute of the United States. It guides the development of national standards, as well as promoting those standards internationally. The best-known ANSI standard in the computer world is a method for representing keyboard characters using standard four-digit numeric codes.

12. Fast Ethernet

Fast Ethernet can transmit data at speeds of 100 Mbps. Fast Ethernet can use either coaxial cables or optical fibers. 100Base-TX is the most widely used medium for Fast Ethernet. It uses two pairs of category 5 copper cables. 100Base-FX implements Fast Ethernet over optical fiber. It uses two strands of the fiber - one to transmit and the other to receive signals.

13. Gigabit Ethernet

In 1998, a more powerful version of Ethernet was introduced. Known as Gigabit Ethernet, this new standard specified a data transmission rate ten times that of Fast Ethernet, at up to 1,000 Mbps - or 1 gigabit per second. The first version of Gigabit Ethernet, published under the 802.3z standard and known as 1000Base-X, was divided into a series of standards, including 1000Base-SX, 1000Base-LX, and 1000Base-CX. It also includes the 1000Base-LH series. The second version, published in 1999 under the 802.3ab standard, defined the 1000Base-T standard, which is the dominant Gigabit Ethernet standard today. This standard uses CAT5 and CAT6 unshielded twisted pair, or UTP, cable

1. Networking Standards

Networking standards are sets of specifications, guidelines, or characteristics applied to network components to ensure interoperability and consistency between them. For example, networking standards specify the size, shape, and types of connectors for attaching network cables to devices.

11. Standard Ethernet

Standard Ethernet is the original Ethernet technology, and can transmit data at speeds of 10 Mbps. It has been superseded by more advanced Ethernet technologies. Standard Ethernet can use either coaxial cables or twisted-pair cables to transmit data for distances up to 500 meters, or about 547 yards. Standard Ethernet can also use optical fibers which can be used to transmit data for distances up to 2,000 meters, or about 2,187 yards.

9. What does the 10Base Standards specify?

The 10Base standards specify types of Ethernet, each defined based on transmission speed and the transmission medium that's used.

8. 802.x Standards

The 802.x standards are divided into subcategories to address different networking requirements. The 802.2 standard was developed to address the need for MAC-sub-layer addressing in switches. The 802.2 standard specifies the frame size and transmission rate. Frames can be sent over Ethernet and Token Ring networks using either copper or fiber media. Ethernet protocols refer to the collections standards covered by IEEE 802.3. The IEEE issued this specification to standardize Ethernet and expanded it to include a wide range of cable media. In addition, the 802.3 standard specifies transmission speeds and a signaling method.

4. Institute of Electrical & Electronics Engineers (IEEE)

The IEEE is an organization dedicated to advancing theory and technology in the electrical sciences. The standards wing of IEEE issues standards in areas such as electronic communications, circuitry, computer engineering, electromagnetics, and nuclear science.

7. Internet Engineering Task Force (IETF)

The IETF is an international open committee, consisting of working groups and commercial organizations that work together to develop and maintain Internet standards. All published Internet standards documents, known as Requests For Comments, or RFCs, are available through the IETF.

3. International Organization for Standardization (ISO)

The ISO is the largest standards-development body in the world, comprising the national standards institutes of 162 countries. It's a non-governmental organization that issues voluntary standards in fields ranging from agriculture to textiles. ISO standards related to networking include the Open Systems Interconnection, or OSI, model. This is a reference model that describes network communication in terms of functions that occur at each of seven layers. Particular protocols are associated with each layer.

6. Telecommunications Industry Association (TIA) & Electronic Industries Alliance (EIA)

The TIA and EIA, are two trade associations accredited by ANSI to develop and jointly issue standards for telecommunications and electronics.

10. Each Ethernet type is identified, how?

Using standard notation that includes three elements. For example, consider the three elements in 10Base-T: • the first element - in this case 10 - represents the approximate maximum transmission rate in megabits per second. • the second element - in this case Base - specifies whether transmission is broadband or baseband, and • the third element - in this case T, which refers to twisted pair cable - specifies the type of cable

2. Networking standards can be either:

• de facto standards, meaning that they've been publicly accepted as a result of their widespread adoption, or • de jure standards, meaning that they're mandated by law or have been approved by a recognized organization or body of experts
