Abstract

The invention provides a method and apparatus for determining the type of an optical network unit (ONU), and an optical line terminal (OLT). The method comprises the following steps: receiving data sent by a specific ONU, and determining a data transmission channel for transmitting data; and according to corresponding relations between data transmission channels and ONU types, determining an ONU type corresponding to the data transmission channel, and taking the determined ONU type as the type of the specific ONU. According to the invention, the problem of operation complexity of a passive optical network coexistence mode in related arts is solved, and the operation complexity is reduced.

Description

technical field [0001] The present invention relates to the field of optical communication, in particular to an ONU type determination method and device, and an OLT. Background technique [0002] According to the working mechanism, passive optical network equipment can be divided into Ethernet-based passive optical network equipment (Ethernet Passive Optical Network, referred to as EPON), 10G Ethernet-based passive optical network equipment (10G Ethernet Passive Optical Network, referred to as 10GEPON), thousand Gigabit-capable Passive Optical Network (G-PON for short), NG passive optical network equipment (N Gigabit-capable Passive Optical Network One, NG-PON1 for short) and passive optical network equipment with other working mechanisms ( Such as 10GEPON, 10GPON, WDM-PON, etc.), among which, NG passive optical network equipment refers to NG-PON1 type equipment, which is divided into two types, XGPON1 and XGPON2, and XGPON1 is an asymmetric system of downlink 10Gbps / uplink ...
