1. How Fiber Optics Work S1170165 Yusuke Fukaya

3. The optical fiber is thin at human's hair level. And, it carries digital information farther.

4. Moreover, it might be used for medical imaging and the mechanical engineering check.

6. Single-mode fibers communicates by using infrared rays.

7. Moreover, Multi-mode fibers communicates by using infrared rays and the light emitting diode.

9. However, the signal of the repetition of the reflection becomes weak.

11. Optical Regenerator can recover the lost light. So to speak, it is a laser amplifier.

12. Optical Receiver receives the light signal by using photocell or photodiode.

15. The optical fiber is made from the outer cylinder. It is very precise work.

16. Finally, it tests separately for some items. It completes it by this.
