안녕하세요. 개알못입니다~~

이번 포스터는 데이터통신 과목에서 Multiplexing 에 관하여 다루겠습니다.

 

중간고사가 6.2절이므로, 추후에 추가해서 올릴 예정입니다 :)

- Multiplexing

Share high medium bandwidth

Simultaneous transmission of multiple signals over a single data link

Share one link between n lines

FDM(analog), WDM(analog), TDM(digital)

 

6.1 FDM

 

- FDM

An analog multiplexing technique that combines signals.

Bandwidth split with multiple carriers

Unused bandwidth strips: guard bands

---

6.2 WDM

 

- WDM ( Wave Division Multiplexing )

fiber-optic cable for high data rate

Conceptually smae with FDM

Very high frequency

Multiple light sources
