Optical network terminal unit (ONT)

Block diagram

Overview

Our integrated circuits and reference designs help you create optical network terminal (ONT) units that enable high-speed data connections for today's passive optical networks. Use the resources below to design a system with our most advanced microcontroller, interface and power delivery technologies.

Design requirements

Modern ONT units often require:

  • An RF transceiver with integrated microcontroller for 802.11 standard compliance.
  • Gigabit Ethernet link for high-speed data connections.
  • Efficient, low-standby Power over Ethernet (PoE) pass-through to power peripheral devices.
