which modulation technique is widely used in optical fiber communication?and why?
can we use ofdm signals in optical communication?and how?

sir,
i want all study report related to optical fiber communication .
i will study those material for submitting seminar and also clear my doubt about modulation techniques in optical communication.
this field/topic is my area of interest,and i really want to study,try to implement it.
thank you!


regards

Mention optical communication and most people think of fiber optics. But light travels through air for a lot less money. So it is hardly a surprise that clever entrepreneurs and technologists are borrowing many of the devices and techniques developed for fiber-optic systems and applying them to what some call fiber-free optical communication. Although it only recently, and rather suddenly, sprang into public awareness, free-space optics is not a new idea. It has roots that go back over 30 years--to the era before fiber-optic cable b ....etc

INTRODUCTION
When we talk about optical communication, most people think about optical-fiber. But optical communication is also possible without optical-fiber. We know that light travels through air for a lot less money. This makes possible the optical communication without optical-fiber. Optical communication without fiber is known as Free Space Optics. It is used due to economic advantages. Since the introduction of internet the backbone traffic is increasing at the rate greater than 100%, hence the owner of the backbone ....etc
