The act of demodulating converts broadband video to baseband video. Fiber optic allows the signal to be transmitted farther without being repeated. Cable companies use a hybrid system using fiber to transmit the signal to neighborhoods and then changes the signal from light to radio frequency to be transmitted over coaxial cable to homes.
A baseband signal or lowpass signal is a signal that can include frequencies that are very near zero, by comparison with its highest frequency (for example, a sound waveform can be considered as a baseband signal, whereas a radio signal or any other modulated signal is not). [2] A baseband bandwidth is equal to the highest frequency of a signal ...
In telecommunications engineering, this is a broadband signaling technique. [a] Broadband provides several advantages over the baseband signal used, for instance in 10BASE5. Range is greatly extended (3,600 m (11,800 ft), versus 500 m (1,600 ft) for 10BASE5), and multiple signals can be carried on the same cable. 10BROAD36 can even share a ...
The term “broadband” refers to a high-speed internet connection that uses a satellite, digital subscriber line or cable connection for data transmission. A broadband connection is usually a lot faster than a dial-up connection and allows you to browse the web and download videos, music and games much more quickly.
The first Ethernet standard, known as 10BASE5 (ThickNet) in the family of IEEE 802.3, specified baseband operation over 50 ohm coaxial cable, which remained the principal medium into the 1980s, when 10BASE2 (ThinNet) coax replaced it in deployments in the 1980s; both being replaced in the 1990s when thinner, cheaper twisted pair cabling came to dominate the market.
An Ethernet extender (also network extender or LAN extender) is any device used to extend an Ethernet or network segment beyond its inherent distance limitation which is approximately 100 metres (330 ft) for most common forms of twisted pair Ethernet. These devices employ a variety of transmission technologies and physical media (wireless ...
