Study Notes
- Ethernet is the most widely used networking technology, used for connecting devices and organizations.
- There are different types of Ethernet connections, including baseband and broadband. Baseband technology uses a single frequency for transmission across a medium, while broadband uses multiple frequencies.
- Older Ethernet standards, such as 10BASE-T (10-megabit Ethernet), used baseband technology and required Category 3 cable. This standard had a maximum distance of 100 meters.
- Faster Ethernet standards, such as 100BASE-TX (100-megabit Ethernet), used all four pairs of wires within a cable and required Category 5 cable. This standard had a maximum distance of 100 meters.
- Gigabit Ethernet, 1000BASE-T (gigabit Ethernet over Category 5 cabling), used all four pairs of wires and required a higher frequency for communication. It had a maximum distance of 100 meters, and required Category 5e cable.
- 10GBASE-T (10 gigabit Ethernet over copper) uses all four pairs of wires and requires a minimum of Category 6 cabling. It uses a higher frequency for communication and has a maximum distance of 55 meters for unshielded cables and 100 meters for shielded cables.
- Category 6A cabling can support 10GBASE-T over both shielded and unshielded cables up to 100 meters.
- 40GBASE-T (40 gigabit per second Ethernet over twisted pair cabling) requires a minimum of Category 8 cable and only allows communication up to 30 meters based on the 40GBASE-T standard.
- Ethernet signals can also be transmitted over fiber using standards such as 100BASE-FX (100-megabit Ethernet over fiber) and 10GBASE-SR (10-gigabit Ethernet over short-range multi-mode fiber). These standards allow for longer distances than copper cabling.
- Wavelength-Division Multiplexing (WDM) allows for multiple signals to be sent over the same strand of fiber using different wavelengths. This technology can be used to increase the capacity of a fiber optic link.
- Coarse Wavelength-Division Multiplexing (CWDM) and Dense Wavelength-Division Multiplexing (DWDM) are types of WDM that use different numbers of carriers. CWDM uses four carriers at different wavelengths, while DWDM uses multiple carriers on a single fiber.
