Embodiment 1

[0062] see figure 1 , figure 1 It is a schematic flowchart of a method for automatically enabling a forward error correction code function provided by an embodiment of the present invention. Such as figure 1 As shown, the method includes:

[0063] Step S10: Determine the sending rate of the test message according to the line bandwidth;

[0064] Specifically, the line bandwidth refers to the bandwidth allocated by the optical line terminal to the optical network terminal, wherein the line bandwidth can be allocated dynamically to better realize the effective utilization of line resources. The sending rate of the test message may be determined according to the bandwidth dynamically allocated to the optical network terminal by the optical line terminal. It can be understood that the sending rate of the test message should not exceed the line bandwidth. For example: you can set the sending rate of the test message as 90% of the line bandwidth, and send the test message at the...

Embodiment 2

[0079] see figure 2 , figure 2 It is a schematic diagram of an application scenario for automatically enabling the forward error correction code function provided by the embodiment of the present invention, as shown in figure 2 As shown, the optical line terminal sends the test message to the optical network terminal, and the optical network terminal sends the test message back.

[0080]Wherein, the method for automatically enabling the forward error correction code function includes: determining the transmission rate of the test message according to the line bandwidth; according to the transmission rate, sending the test message to the optical network terminal, and notifying the optical network The terminal sends back the test message; judges the line quality according to the test message returned by the optical network terminal; determines whether to enable the forward error correction code function according to the line quality.

[0081] Specifically, after the optical...

Abstract

The embodiment of the invention relates to the field of fiber-to-the-home communication, and discloses a method and device for automatically opening a forward error correction code function and an optical line terminal. The method for automatically opening the forward error correction code function includes the following steps: determining the sending rate of a test message according to the line bandwidth; sending the test message to an optical network terminal according to the sending rate, and notifying the optical network terminal to send the test message back; judging the line quality according to the test message returned by the optical network terminal; and determining whether to open the forward error correction code function according to the line quality. Through the above mode, the embodiment of the invention can improve the ability of judging the line quality, reduce the maintenance cost of the line, and achieve the balance between the line quality and the line bandwidth.

Description

technical field [0001] The invention relates to the field of fiber-to-the-home communication, in particular to a method, a device and an optical line terminal for automatically enabling a forward error correction code function. Background technique [0002] With the continuous development of Fiber To The Home (FTTH) technology, a large number of passive optical network systems have been applied to provide users with greater bandwidth services. However, due to the different networks and environments in different regions, the line quality varies, resulting in a high bit error rate. In order to solve the bit error problem, Forward Error Correction (FEC) technology has been widely used. FEC is a data encoding technology. The data sending end adds a certain redundant error correction code to the data message to be sent, and the receiving end performs error detection according to the error correction code. In the FEC mode, the receiving end can not only find the error, but also d...
