Abstract: Disclosed are an optical fiber connector assembly, an optical fiber connector plug, and an adapter assembly, comprising an optical fiber connector plug, an optical fiber connector adapter, and an adapter base plate. A plug information storage chip and an indicator light-guiding pillar are arranged in parallel on a bottom side of the optical fiber connector plug. Each pin of the plug information storage chip is electrically connected to conductive slide-rails. Metal elastic pins and an indicator light accommodation portion are arranged in parallel on a bottom side of a plug opening of the optical fiber connector adapter. Pin contacts and an indicator light are arranged in parallel on the adapter base plate. When the adapter is mounted on the adapter base plate, the indicator light is accommodated in the indicator light accommodation portion and the metal elastic pins are electrically connected to the pin contacts.

Abstract: The present invention provides a method and apparatus for implementing trunk optical fiber protection in EPON. According to the technical scheme of the present invention, activating an optical module at a master PON port, deactivating an optical module at a standby PON port, configuring a service for the master PON port, and synchronizing static data and dynamic data to the standby PON port; synchronizing and adjusting a value of an MPCP counter at the standby PON port according to a value of an MPCP counter at the master PON port; and carrying out fault detection, transmitting an operating state to the standby PON port when the fault occurs, and performing a master-standby switch of the PON ports.

Abstract: A multicast control method in an Ethernet passive optical network, the method includes steps: (A) configuring different id for user-end devices and their user ports; labeling users on office-end devices by using id for user-end devices and their user ports; setting up user's multicast authorization table; (B) based on the multicast authorization table, office-end devices control user's multicast authority; based on the controlled result, setting up multicast filtration tables and user filtration tables for user-end devices; based on the multicast filtration tables and user filtration tables, user-end devices filter multicast data, and forward them to users having multicast authority. The method controls multicast for different user ports on the same user-end device so as to raise security of multicast.
