Embodiment 1

[0052] Such as figure 1 and Figure 4 As shown, the EPON link data acquisition and analysis device of this embodiment is set between the OLT (Optical Line Terminal) 4 and the 1:32 / 64 optical splitter 6 .

[0053] The EPON link data acquisition and analysis device in this embodiment includes a link optical splitting module 1 , a protocol analysis module 2 and a data analysis module 3 . Wherein, the output end of the link splitting module 1 is connected to the input end of the protocol analysis module 2 , and the output end of the protocol analysis module 2 is connected to the input end of the data analysis module 3 .

[0054] In the EPON link data acquisition and analysis device in this embodiment, the link optical splitting module 1 includes a 2-by-2 optical splitter 13, a first uplink optical port 71, a first downlink optical port 72, and a second uplink optical port 73 and the second downlink optical port 74, the first uplink optical port 71 and the first downlink optical ...

Embodiment 2

[0061] Such as figure 1 and Figure 5 As shown, the EPON link data acquisition and analysis device of this embodiment can also be arranged between the ONU end 5 and the 1:32 / 64 optical splitter 6 .

[0062] The EPON link data collection of the present embodiment and the analysis device structure are identical with embodiment 1, the optical fiber of ONU end 5 and the first uplink optical port 71 of link splitting module 1 (that is figure 1 The uplink optical port 11) in the link is connected, and the OLT end passes through the 1:32 / 64 optical splitter 6 and the first downlink optical port 72 of the link splitting module 1 (ie figure 1 The downlink optical port 12) in the connection.

[0063] In this embodiment, when the optical signals from the ONU end 5 and the OLT end 4 pass through the link splitting module 1, the uplink data optical signal of the ONU end 5 and the downlink data optical signal of the OLT end 4 are divided into two optical splitters 13, and transmit to the...

Abstract

The invention discloses an EPON link data collecting and analyzing device which comprises a link beam split module, a protocol analyzing module and a data analyzing module. The link beam split module is used for receiving EPON light signals and separating uplink EPON light signals and downlink EPON light signals. The protocol analyzing module is connected with the link beam split module and is used for reverting the received uplink EPON light signals and the received downlink EPON light signals into Ethernet data frame signals which are transmitted to the data analyzing module. The data analyzing module is connected with the protocol analyzing module and is used for collecting and analyzing data from the received Ethernet data frame signals. The invention further provides an EPON link data collecting and analyzing method. EPON data collecting and protocol analyzing are achieved, non-object data and useless data filtering is achieved, decryption on collected EPON data is achieved, restoring of the network record of a target user is achieved, user normal use daily service is not affected, and even if equipment power failure happens, all users can work normally.

Description

technical field [0001] The invention belongs to the technical design field of electric communication, and in particular relates to a device and a collection and analysis method for EPON link data collection and analysis. Background technique [0002] At present, network data collection and protocol analysis technology is widely used in the security industry, public security system and network management and equipment maintenance of operators. ADSL network data acquisition and protocol analysis technology is to collect the electrical signal of data transmission in the ADSL network, restore the electrical signal and analyze the corresponding protocol to obtain the Ethernet data frame. [0003] With the gradual deployment of the national FTTH (fiber-to-the-home) network, the scale of the optical fiber network in my country continues to expand, and the number of users also increases rapidly. EPON (Ethernet Passive Optical Network) is one of the mainstream technologies of optica...
