Question 15

(single) Regarding EPON, which of the following descriptions is incorrect?

Select an option, then click Submit answer.

  • ○

    The EPON standard is one of the many TDM-PON standards. It has the basic characteristics of the
    TDM-PON network: the tree topology network consists of three parts: the OLT, the ONU, and the ODN (Optical Distribution Network).
  • ○

    On the logical topology, the EPON protocol establishes a logical link for the OLT to each ONU. The leading byte of the Ethernet data frame carries the logical link identifier, that is, LLID (Logical Link Identity).
  • ○

    The downstream data stream from the OLT to the ONU is encapsulated into an Ethernet message, and the corresponding LLID is appended and transmitted in the tree PON network. The optical splitter in the ODN broadcasts the data stream to each branch, and all ONUs can receive the downlink Ethernet data frame and selectively receive its own data according to the LLID.
  • ○

    From the ONU to the OLT in the uplink direction, each ONU uses the broadcast mode to share the uplink bandwidth.
