Ethernet Standards

Ethernet Standard

• IEEE 802.3 standard used on networks for communication.

• Network cables follows a BASE standard.

Copper Ethernet Standards

• 10BASE-T - Known as IEEE 802.3i, supports 10 Mbps with a signaling method as BASE which uses Twisted Pair (T) media (Cat 3).

• 100BASE-TX - Known as IEEE 802.3u, supports 100 Mbps with a signaling method as BASE which uses a Pairs of Twisted Pairs (TX) media (Cat 5).

• 1000BASE-T - Known as IEEE 802.3ab, supports 1 Gbps with a signaling method as BASE which uses Twisted Pair (T) media (Cat 6).

• 10GBASE-T - Known as IEEE 802.3an, supports 10 Gbps with a signaling method as BASE which uses Twisted Pair (T) media (Cat 6, Cat 6a & Cat 7). The Cat 6 cables has a reduce distance of 55 meters when working with 10GBASE-T standard.

• 40GBASE-T - Known as IEEE 802.3bq, supports 40 Gbps with a signaling method as BASE which uses Twisted Pair (T) media (Cat 8).

Content Based Access

• Carrier Sense Multiple Access / Collision Detection (CSMA/CD) - Allows only one device to transmit at a time on a wired Ethernet network. Before a sender transmits a message, it will check the media to determine if there is an existing signal. If a signal is detected, the sender will re-check after some time to determine whether a signal still exist on the media. If not signal is found on the media, the sender will transmit it's message. If 2 devices transmits at the same time on a content-based network, a collision occurs.

• Carrier Sense Multiple Access / Collision Avoidance (CSMA/CA) - Allows one wireless device to transmit at a time on a wireless network. Before a wireless client sends a message across the wireless network, it will as the wireless router if the network is clear before transmitting. If the wireless client receives an all-clear, it will proceed to transmit the message.

Fiber Ethernet Standards

• 100BASE-FX - Known as IEEE 802.3u, which supports FastEthernet speeds on Multimode Fiber (MMF).

• 100BASE-SX - Known as IEEE 802.3u, which supports FastEthernet speeds on short-range Multimode Fiber (MMF).

• 1000BASE-SX - Known as IEEE 802.3z, which supports GigabitEthernet speeds on Multimode Fiber (MMF).

• 1000BASE-LX - Known as IEEE 802.3z, which supports GigabitEthernet speeds on long-range Single mode Fiber (SMF).

• 10GBASE-SR - Known as IEEE 802.3ae, which supports 10 GigabitEthernet speeds on short-range Multimode Fiber (MMF).

• 10GBASE-LR - Known as IEEE 802.3ae, which supports 10 GigabitEthernet speeds on long-range Single mode Fiber (SMF).
