Abstract: A conformance testing method including: obtaining a testing symbol pattern in an optical signal; performing equalization compensation on the testing symbol pattern; generating a testing eye pattern; calculating a value of a first parameter based on the testing eye pattern and a noise enhancement coefficient, where the first parameter is used to determine a transmitter dispersion eye pattern closure degree of the optical transmitter; and when the value of the first parameter is less than or equal to a preset threshold, determining that conformance testing on the optical signal succeeds.

Abstract: Disclosed are an adaptive frequency domain resource configuration method, an apparatus, and a communications system. The method includes receiving, by a receiving apparatus, a pilot signal transmitted by a transmitting apparatus and feeding back channel information of a channel for transmitting the pilot signal to the transmitting apparatus by measuring the pilot signal, so that the transmitting apparatus divides a bandwidth frequency of the transmitting apparatus according to the channel information. The receiving apparatus can feed back the channel information to the transmitting apparatus according to the received pilot signal, so that the transmitting apparatus can divide the bandwidth frequency according to channel quality, and adaptive adjustment can be performed on a frequency domain resource of each subcarrier according to the channel information fed back by the receiving apparatus.

Abstract: Embodiments of this application provide a link resource transmission method and apparatus. The method includes the following steps. A first node floods first control routing information, where the first control routing information includes an identifier of an area in which the first node is located. A second node floods second control routing information, where the second control routing information includes an identifier of an area in which the second node is located. The first node determines, through comparison, whether the identifier of the area in which the first node is located is consistent with the identifier of the area in which the second node is located. When the identifier of the area in which the first node is located is consistent with the identifier of the area in which the second node is located, the first node transmits link data information of the first node to the second node.
