Optical Network Design and Implementation

Chapter 2. Time-Division Multiplexing

This chapter includes the following sections:

• An Introduction to Time-Division Multiplexing— TDM is a common way to send multiple signals or streams of information over a medium at the same time in the form of a single, complex signal, and then recover the separate signals at the receiving end. In a TDM scheme, several low-speed channels are multiplexed into a single high-speed channel for transmission over a network.

• Analog Signal Processing— This section presents the various stages involved with analog signal generation and reception, analog-to-digital conversion, signal filtering, sampling, quantization, encoding, and µ-law and A-law coding for pulse code modulation (PCM).

• Circuit-Switched Networks— Circuit-switched ...
