Q21: What is CATV cables?
A21:CATV cabling is a 75 ohm coaxial cables commonly known for transmission
of Cable TV signals, but is also used with Ethernet 10Broad36 networks.
CATV stands for "community antenna television".
CATV cabling is used for "broadband" transmission as opposed
to the "baseband" transmission used by all other Ethernet physical
layers. A broadband cabling system supports transmission of multiple services
over a single cable by dividing the bandwidth into separate frequencies,
with each frequency assigned to a different service. This technique is
used in cable TV transmission systems to transmit multiple channels over
a single cable. Each channel uses a different frequency range. This capability
can allow 10Broad36 share a single cable with other services such as video.
