Indicates the channel of control signal.



Indicates the channel of service signal.



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 16 XGS-PON ports.

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



Indicates the channel of power or clock signal.



  • 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.
