An optical communication repeater is a carrier of all the new digital signal forms. It converts the electronic signal to light and sends it out to the other fiber. Analog Repeater: This repeater transmits data in analog signals. It amplifies the analog signals and sends it to the next receiver. Digital Repeater : Also called as a digipeater, transmit data in binary digital signals.
This amplifies the digital signal and also, if required, repairs the losses over the medium it is received from. In networking, a repeater is used to connect two LAN signals. It is not possible to connect all the devices through wires.
Repeater makes it easy to expand the coverage and access network to a greater scale with the same signal strength. Repeaters are used to extend transmissions so that the signal can cover long distances. It creates an extended range of the signal and makes it accessible till the destination which was not possible only with the router. In a wireless communication system, a repeater takes the existing signal from an access point and rebroadcasts to create a second network.
This is a two-port device. This is commonly used in homes and small offices to make the signal available to a larger extent. This strengthens the signal and extends the coverage area of the Wi-Fi network. A repeater is often considered as a non-logical device as it rebroadcasts each bit by bit regardless of its feature. It supports both analog and digital signals. It removes unwanted noise from the signal. Even when the signal is weak or distorted it is absorbed and is strengthened again.
Digital repeaters can even reconstruct the signals which are distorted by transmission. It repropagates a broken signal. Repeaters are easy to install.
It is cost-effective and does not require a unique installation process. A few of the disadvantages are; it connects only to a similar network, it cannot differentiate noise, it cannot reduce traffic or congestion, and routers or networks might have limitations on the number of repeaters that can be installed. As mentioned, the repeater has two ports, a hub is a multiport repeater. It can carry multiple connections.
Optical Repeater : These types of repeater are used for fiber optic communication system. This repeater grabs the optical signals into electric form. It is capable to reshaping and amplification operations before getting to retransmission. Radio Repeater : Radio repeater transmits the all data into radio signals. It contains two ports; one is radio receiver and other radio transmitter.
Radio receivers helps to grab the data in the form of signals, and radio transmitter helps to retransmits the data which are obtained from the repeater. Telephone Repeater : Telephone repeater can be used for long range communications.
In this repeater, amplifier is used that is consisted the transistors for enhancing the power. This telephone repeater uses the bidirectional communication system that means data is broadcasted in the form of audio signals. The main use of this telephone system is in the submarine communications. A repeater is used for performing several functions; below explain each one —.

Hence repeaters are capable of carrying electric as well as light signals. In order to achieve greater and efficient signal length, often repeaters are used in the Ethernet.
The purpose of the Ethernet repeater is to carry signal from one Ethernet cable and take it to the other cable without attenuation or loss of signal strength. More over repeater helps system to work powerfully by detecting any collision. If a repeater identifies any collision, it sends the signal to the all connected ports.
Repeater is used to connect various segments in an Ethernet. A multiport repeater is often used for this purpose. If between two host devices there are more than five segments. Often repeaters can detect improper links; hence data flow is terminated till the accuracy or rectification of data.
Repeaters are smart devices; they regulate the signals and control the signal flow. As a result the wires can be protected from damage or breakage. Repeaters also enable the continuous working of the network segments, if though if one of the segment is broken and it is unable to perform the function.
