List of Figures

Chapter 1: An Introduction to Optical Access Networks Technological Overview and Regulatory Issues for Large-Scale Deployment

Figure 1: FTTH deployment architectures (a) point-to-point; (b) curb-switched active Ethernet, and; (c) passive optical Network (PON).
Figure 2: A simple WDM-PON implementation where multiple wavelengths are assigned for communication between the various Optical Network Units (ONUs) and the Optical Line Termination (OLT).
Figure 3: A carrier-neutral open-access FTTH scheme illustrating the three major operational roles

Figure 1: An abstract view of an active optical access network
Figure 2: The general structure of an active optical access network using an SDH transport network
Figure 3: Narrowband and transport (SDH-type) multiplexers of an ONU
Figure 4: Line Cards with POTS, "U" or Voice-Frequency (VF) interfaces.
Figure 5: Provision of E1 services (2048 Mbit/s) through an ONU. HDSL devices are used in case signal attenuation between the user and the ONU exceeds a prescribed value (e.g. 6 dB at 1 kHz)
Figure 6: Schematic of a typical subrack of a narrowband multiplexer. In this subrack, it is considered that each...
