Title:
The method, device, and communication node for controlling the output noise of PCIe fiber-optic communications
Document Type and Number:
Japanese Patent JP6175709
Kind Code:
B2
Abstract:
A method, an apparatus, and a communication node for suppressing output noise of PCIe optical fiber communication is provided, where the method includes: detecting a differential-mode voltage of a transmit end of an interface module; and, when the differential-mode voltage is lower than a threshold, controlling an optical module connected to the interface module to be disabled. In an application of the embodiments of the present invention, when two communication parties communicate with each other by using an optical fiber, and when a differential-mode voltage of a signal transmitted by a transmit end is lower than a threshold, an optical module is controlled to be disabled, so that the transmit end cannot output a noise signal. This prevents a receive end from receiving an abnormal signal and ensures that an optical fiber communication line is normal.
