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

Why fiber?
Speed- operates at high speed upto gigabits
Bandwidth- large carrying capacity
Resistance- to EM noise
Provide electrical isolation
Distance- Signals can be transmitted further without need of repeaters
Maintenance cost- less
Requirements of digital fiber link
No. of digital signal 8
No. of fiber cable 1
Signal frequency- 0-20KHz
I/p-O/p voltage level- 0 & 24 V for (0 & 1 digital logic)
Transmission Range- 300m
Here, we have selected HFBR-1521 transmitter and HFBR-2521 receiver. Spec ....etc

This article presents a fiber-optics-based sensing network for fault detection in power systems. This scheme is considered secure and immune from interferences. A passive rugged fiber-Bragg-grating-based sensors are present a each of the monitoring locations. magnetostrictive transducers are used in the place of CT or PT for the purpose of converting the magnetically induced currents into optical signals. The temperature drift in these sensors can be easily compensated for. An increased fault current at a certain location causes a surge in the ....etc

Good day,

I am a masters student of Covenant University. i needed a topic on fiber optics communication for my thesis.

I have written a seminar on fiber optics broadband so i know a lot on fiber optics and with this it has being on my mind to work on it for my thesis which can also be useful in Nigeria which is my country.

Thanks for your assistance, i will be expecting your reply.

Your faithfully

Atop each of the Trump towers in New York City, there's a new type of wireless transmitter and receiver that can send and receive data at rates of more than one gigabit per second -- fast enough to stream 90 minutes of video from one tower to the next, more than one mile apart, in less than six seconds. By comparison, the same video sent over a DSL or cable Internet connection would take almost an hour to download.

This system is dubbed 'WiFiber' by its creator, GigaBeam, a Virginia-based telecommunications startup. Although the technology ....etc
