Abstract |
|
Increase in the number of users increases the interference between the signals and decreases the bit error rate (BER). This sets a limit for number of users in the given bandwidth in optical fiber. To improve the bit error rate of the system uniform fiber bragg grating is used at transmitter and receiver end with same reflectivity. With distance, performance of OCDMA decreases. To check the effectiveness of FBG on OCDMA in optisystem simulink software, various lengths of optical fibre are taken and bit error rate is checked. Comparison of BER and various parameters of eye diagram is done with FBG and without FBG. |
