Difference between noise and interference in optical communication?
Wiki User
∙ 11y ago
Interference and noise are distinguished the same way in all situations not just optical communication. Noise is caused by random thermal effects or statistical effects to to the randomized distribution of electron flow. Interference is due to a system being sensitive to external perturbation, due to weather, dust, vibration etc.

What is Relationship between electrical and optical bandwidth for an optical fiber communication?
The electrical bandwidth refers to the frequency range that the electronic components in the communication system can handle, while optical bandwidth refers to the frequency range that the optical fiber can transmit. The relationship between the two bandwidths is important in ensuring that the data transmission is efficient and reliable. Matching the electrical and optical bandwidths helps to avoid signal degradation and distortion in the communication system.
Why optical communication is used in long distance communication?
Because it transmits data much faster, cooler, and with less chance of interference than metal cable.
What is the Difference between optical zoom and dynamic zoom?
ofcourse optical zoom..................
What is the difference between a mirage and an optical illusion?
All mirages are optical illusions but all optical illusions are not mirages.
What is the difference between and optical illusion and an illusion?
All mirages are optical illusions but all optical illusions are not mirages.
What is the definition of 'optical satellite communication'?
definition of optical satellite communication
What is the difference between a dvd player and a optical dvd player?
The difference between optical and non optical is the way the drive in the DVD reads the disk. Optical is a better and more higher quality reader. So the picture is much better.
What is Difference between optical communication and microwave communication?
Only the frequency of the communications carrier. Microwaves are electromagnetic radiation in the frequency range of 3 gigahertz to 300 gigahertz. Electromagnetic radiation above those frequencies are considered "optical" even though you can see only a small percentage of them with your eyes.
What is the difference between a optical microscope and a non- optical microscope?
light is must for optical microscope while is not necessary for nonn optical one
How does a twopoint interference pattern form?
Interference effects can be observed with all types of waves, for example, light A simple form of interference pattern is obtained if two plane waves of the same Optical interference between two point sources for different wavelengths and
Are noise and interference major propagation problems for optical fiber propagation?
No. Fiber is immune to electrical interference; there is no cross-talk between signals in different cables and no pickup of environmental noise.
What cable type is immune to outside interference?
optical fibre
