play



Indicates the control signal channel.



Indicates the service signal channel.



Control module: loads the board software, controls the running of the board, and manages the board.



  • Service processing module: aggregates and forwards the signals from 8 XG-PON ports.

  • Interface module: conversion between XG-PON optical signals and Ethernet packets.



Indicates the power or clock signal channel.



  • The power module supplies power to each functional module of the board.

  • The clock module provides clock signals for each functional module of the board.
