  15. 15. FTTH Electronics Unmanaged Switch OLT Encoder & DVD Fiber Management A typical FTTH network has an “Optical Line Terminal” (OLT) or switch at the “Headend” or “Central Office” The OLT or switch converts incoming traffic into laser pulses and sends them down the fiber. …And an “Optical Network Terminal” (ONT), media converter, or gateway in the home. The ONT converts the signals from light to electrical signals. The ONT contains ports to distribute signals on the existing home wiring (or wirelessly). The ONT may be either inside or outside the home. Fiber ONU WWW.JTOPTICS.COM
  16. 16. Typical FTTH Architectures • PON (Passive Optical Network) • Incorporates a signal divider, such as an optical power splitter • One fiber at the central office feeds many fibers in the field • G-PON (Gigabit PON) and GE- PON (Gigabit Ethernet-PON) are the most common architectures • Point-to-Point (“Active Ethernet”) • One fiber in the headend = one fiber in the field OLT Optical power splitter or wavelength filter PON Point to point Switch WWW.JTOPTICS.COM

  45. 45. PON Design Considerations 1. OLT Cost per Port • As the cost per port drops, designs that require a higher utilization of ports but less fiber and splicing become more cost effective 2. Take Rates • As take rates increase, the impact of dedicating OLT ports to a greater number of splitters is reduced 3. Assessing Cost Impacts • When conducting a cost analysis to determine the impact of different design approaches, it is helpful to focus only on cost that vary between the designs • Eliminate costs that are common to the designs being assessed 4. Cost Assessment Focus • Cost effectiveness can be measured in multiple ways: • Cost per household/living unit • Cost per subscriber WWW.JTOPTICS.COM
