Embodiment Construction

[0011] The embodiments of the present invention will be described in further detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0012] This solution is mainly to solve the problem that BOSA cannot register when the downstream light of ZTE OLT is stronger than -10DB and less than -15DB. This solution is to monitor the ONU in real time. When the receiving power of the ONU is too strong, reduce the ONU's TX light emission Power, which ultimately enables ONUs to be successfully registered under ZTE's OLT.

[0013] When the ONU receives too much light and cannot be registered on the OLT, the ONU is cyclically monitored whether the current ONU is emitting long light and its received light power, and the power level scaling ratio is adjusted to adjust the ONU's TX luminous power, and finally the ONU can be successfully registered in the ZTE OLT ....

Abstract

The invention discloses a method for dynamically adjusting ONU light emission based on a powerlevel function. The method comprises the following steps: S1, obtaining whether a current ONU emits lightfor a long time or not, and obtaining the light receiving power of the current ONU; S2, if the current ONU is in the long light-emitting mode, setting the power level zoom ratio to be 1; if the current ONU is in a non-long light emitting mode and the light receiving intensity of the ONU is greater than -15dBm, setting the power level zoom ratio to be 0.5; and if the current ONU is in a non-long light emitting mode and the light receiving intensity of the ONU is less than -17 dBm, setting the power level zoom ratio to be 1. Whether the current ONU emits light for a long time and the light receiving power of the current ONU are circularly monitored through threads, the TX light emitting power of the ONU is adjusted by adjusting the power level level zoom ratio, and finally the ONU can be successfully registered in a Zhongxing OLT.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to passive optical network technology, in particular to a method for dynamically adjusting ONU light emission based on a powerlevel function. Background technique [0002] When the ONU receives too much light, the ONU cannot be registered on the OLT. Summary of the invention [0003] The purpose of the present invention is to provide a method for dynamically adjusting ONU light emission based on the powerlevel function in view of the above-mentioned shortcomings of the prior art. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: [0005] A method for dynamically adjusting ONU light emission based on the powerlevel function includes the following steps: [0006] S1: Obtain whether the current ONU is emitting light for a long time and obtain the received optical power of the current ONU. [0007] S2: If the current ONU is in...
