dc.description.abstract	In this work, the RSA (Rivest, Shamir, Adelman) cipher system was implemented by software. The data in form of speech waveform have been recorded by using a computer microphone. These digital speeches were encrypted, and sent via an optical fiber interface card (Fast Ethernet adapter card) at a bit rate of 100 Mbps to another computer, and then it was decrypted .The encrypted data were transmitted through the optical system using a light emitting diode (LED) with a wavelength of 1310 nm and power of (-14 )dBm. A multimode optical fiber was used as a channel and Positive Intrinsic Negative (PIN) photodiode was used as an optical detector. ‫‫‪The power budgets for distances (3, 10, 15, 20, 25) meters have been‬‬ ‫.‪calculated by using the experimental results‬‬ ‫‪In this work, a program was written to support the RSA cipher algorithms‬‬ ‫	en_US
