Optical Fiber Lossed Measurement


ACKNOWLEDGEMENT

 

Many individual have proudly influenced us during our undergraduate studies (B.Tech.) at SSIET, Derabassi and it is pleasurevto acknowledge thiesr guidance and support.In SSIET, I learned many things, like, the project training is mainly aimed at enabling the student to apply their theoretical knowledge to practical as “The theory is to know how and practical to do how” and to appreciate the limitation of knowledge gained in the class room to practical situation and to appreciate the importance of discipline, punctuality, team work, sense of responsibility, money, value of time, dignity of labour.

 

I will like to express my gratitude towards Miss Vimmy Bhatia who took keen interest in our project,Who helped me in every possible way and is source of inspiration for all the group members.

I would also like to thank Mr. Sanjeev Chopra(hod, Electronics & Communication) who motivated me to complete our  project with enthusiasm and hard work. He helped every time when I need

Optical lossed Measurement

In  this project we will measure optical bend losses using microcontroller 8051 and will display it on 16*2 LCD. We are making this project because wedidnot find any circuit on internet. In brief firstly we convert the LOSSES into small voltage variations with the help of sensor, Output of the sensor is further converted into digital signal with the help of the ADC. IN this project we use ADC0809 . ADC 0809 is a 8 bit ADC and convert the any analogue signal into digital signal in 100 microsecond. To control the ADC we required a clock pulse, and 4 different signal . All this signal is provided by the controller. IN this project we use ic 89s51 as a main controller. IC 89s51 sense the output from the ADC in hex code. This HEX code is further converted into binary code with the help of program code inside the controller. IN the output device we use LCD display . LCD display display the contents of the display with the  help of the ASCII code. ASCII CODE  is a special code for displaying the character in the LCD.  In the controller we convert the binary code in to ASCII codes with the help of the code conversion program.
