What is meant by optical network topology?
What is meant by optical network topology?
Topology: When multiple fiber cables are employed in an optical network, then these are connected through nodes. But the way in which the multiple nodes are connected together denotes the topology of the network.
What are the three topologies used for fiber optical network?
Fiber Access Topologies: Star, Ring (or Bus), and Tree | Home. Several topologies are being used for the optical fiber cable network that connects CO to CP. These topologies are: Star, Ring (or Bus), and Tree topologies. Star topologies are having separate connection for each subscriber.
What are the four components of an optical network?
Components
- Fiber.
- Laser or LED light source.
- Multiplexer/demultiplexer, also called mux/demux, filter, or prism.
- Optical switch, to direct light between ports without an optical-electrical-optical conversion.
- Optical splitter, to send a signal down different fiber paths.
What are the 8 types of topology?
- Mesh Topology. In mesh topology each device is connected to every other device on the network through a dedicated point-to-point link.
- Star Topology. In star topology each device in the network is connected to a central device called hub.
- Bus Topology.
- Ring Topology.
- Hybrid topology.
What are the advantages of optical network?
Here are six major advantages of a fibre optic network:
- Better bandwidth. Fibre optic cables have much greater bandwidth than metal cables.
- Higher bandwidth means faster speed.
- Longer transmission distances.
- Greater flexibility.
- Improved latency.
- Stronger security.
What are the different types of classification of optical network?
The classification based on the mode of propagation of light is as follows: Single-Mode Fibers: These fibers are used for long-distance transmission of signals….Types of Optical Fibers
- Step index-single mode fibers.
- Graded index-Single mode fibers.
- Step index-Multimode fibers.
- Graded index-Multimode fibers.
What are different type of optical network?
There are three types of fiber optic cable commonly used: single mode, multimode and plastic optical fiber (POF).
What are the main parts of optical fiber explain?
A typical optical fiber comprises three main components: the core, which carries the light; the cladding, which surrounds the core with a lower refractive index and contains the light; and the coating, which protects the fragile fiber within.
How many types of topologies are there?
In computer networks, there are mainly two types of topologies, they are: Physical Topology: A physical topology describes the way in which the computers or nodes are connected with each other in a computer network.
What are the limitations of optical fiber communication systems?
Low power—Light emitting sources are limited to low power. Although high power emitters are available to improve power supply, it would add extra cost. Fragility—Optical fiber is rather fragile and more vulnerable to damage compared to copper wires.
What are the uses of optical fibers in the various industries?
Many of us know that fibers are used for the internet communication network but optical fibers are also used in industrial welding application to cut steel for building cars, medical applications where fibers are used for light transmission in endoscopes and removal of artery plaque, kidney stone, etc.
What are the most common network topologies?
Mesh Topology. Mesh Topology: In a mesh network,devices are connected with many redundant interconnections between network nodes.
What are some examples of network topologies?
Bus Topology
What are the types of network topology?
Based on the arrangement of nodes in a network, topologies can be classified as bus, ring, mesh, star, and tree. In these topologies, the network terminals are arranged in a manner suggested by their names. Another type of network topology is hybrid, which uses a combination of two or more topologies.
What is the most common network topology?
The Star or Hub topology is one of the most common network topologies found in most offices and home networks. It has become very popular in contrast to the bus type (which we just spoke about), because of the cost and the ease of troubleshooting.
