Abstract

The invention relates to external optical fiber Bypass equipment. The equipment comprises an optical signal converter, a programmable controller and a power converter, wherein the optical signal converter is connected with the programmable controller; the power converter supplies power to the optical signal converter and the programmable controller; the programmable controller is used for receiving a control signal sent by a host and indicating the optical signal converter according to the control signal; and the optical signal converter is used for switching optical signal channels according to the indication of the programmable controller. On the host with an optical fiber network card, a Bypass function can be realized by allocating the external optical fiber Bypass equipment without replacing any original hardware equipment; and therefore, the equipment has the characteristics of high selectivity, low replacement cost and convenient upgrade.

Description

technical field [0001] The present invention relates to the technical field of optical signal processing equipment, and more specifically, relates to an external optical fiber bypass equipment and a switching method of an optical signal channel. Background technique [0002] Bypass [bypass function, which can prevent two networks from passing through the system of network security equipment through a specific trigger state (power failure or crash)] equipment, places with high real-time requirements, such as government, telecommunications, education, medical care, electricity It is a necessary network switching system for units such as hospitals, transportation, and scientific research institutes, which plays a decisive role in the protection of single-point failures in the line. The network bypass device is used to protect and prevent various network serial gateway devices (such as network firewalls, anti-virus gateways, anti-spam gateways, etc.) from becoming a single point...
