PON gateway receiving optical power automatic adjusting method

Abstract

The invention discloses a PON (Passive Optical Network) gateway receiving optical power automatic regulation method, which comprises the following steps that an optical regulator module is embedded in front of an optical transceiver of a gateway, and the optical regulator module is in a closed state under a default condition; detecting the intensity n of the received original optical signal through a photoelectric detector, and feeding back the intensity n to the upper computer software; judging whether the intensity n of the optical signal is within a reasonable range or not; if the intensity of the received original light is larger than the reasonable receiving range of the light signal intensity, an instruction for increasing light attenuation is issued to the light regulator module through the API interface; if the received original light intensity is smaller than the reasonable receiving range of the light signal intensity; if yes, an instruction for increasing light expansion is issued to the light regulator module through the API interface; and the optical regulator module regulates the optical signal intensity according to the D value or the K value. According to the invention, the problem of light instability in the optical network can be effectively reduced, the maintenance cost is reduced, and the maintenance efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of PON optical network communication, in particular to an automatic adjustment method for receiving optical power of a PON gateway. Background technique [0002] The optical network deployed in my country has covered hundreds of millions of households. The optical network has played an irreplaceable role in social development. Most people are enjoying the convenience brought by the optical network. The optical network can cover 80% of the user environment. , but at the same time, it is also found that in the environment at the edge of the optical network, there are still many problems in the optical network, and there are often situations where the registration cannot be performed or the light is unstable, such as the following scenarios: [0003] Scenario 1) With the rapid increase of bandwidth used by users, although 1G can meet the needs of most users, the demand for 10G is also very strong, resulting in t...
