Because - even in fibre-optic cable, distance brings attenuation of the signal. Repeaters boost the data stream to provide a constant signal level.

How many types of repeaters are there?
Signal repeaters are generally used in the telecommunication and electronics industries. There can be passive radio signal repeaters, multi-port repeaters, optical signal repeaters for optical fiber and digipeaters which repeat packet data.
What is the 5 4 3 rule in networking?
On a standard Ethernet network, between any two devices that communicate (such as computers), you can't have more than 4 repeaters (this includes hubs). "5-4-3" refers to a maximum of 5 segments; 4 repeaters; 3 segments with hosts on them.
What is the maximum number of class 1 fast Ethernet repeaters allowed between stations?
One
Which network topology do nodes act as repeaters?
Star Topology, where Hubs can act as repeaters.
What type of networks are repeaters typically used?
Either a Bus topology or Wireless repeating, depends on how the question is stated...
What function do cell repeaters have?
Cell repeaters have functions like extension of wireless range. When two hosts are being used, they have to be connected using a MAC (Medium Access Control) and a PHY (Physical Layer) but the connection is too long and to make it easier and shorter, one have to use cell repeaters to bridge the gap.
What is RS-232 refers to?
it is cable used for data transmission between computers
What is HTTP used for?
It's a protocol that enables communication between computers and servers.
Explain the advantages and disadvantages of repeaters?
1.It is very expensive as according to the distance the no.of repeaters can be fixed and accordingly the budget or the expenditure will increase or decrease. 2. it takes a lot of time to set a repeaters between two stations.
What kind of network infrastructure can have repeaters?
Wireless networks often use repeaters to extend the network signal to distant locations. Ethernet repeaters are commonplace as well, as there are limits to the lengths that cables will function at.
How do repeaters help networks?
A repeater connects two segments of your network cable. It retimes and regenerates the signals to proper amplitudes and sends them to the other segments. When talking about, Ethernet topology, you are probably talking about using a hub as a repeater. Repeaters require a small amount of time to regenerate the signal. This can cause a propagation delay which can affect network communication when there are several repeaters in a row. Many network architectures limit the number of repeaters that can be used in a row. Repeaters work only at the physical layer of the OSI network model.
