Embodiment Construction

[0044] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0045] The present invention aims at the problem in the prior art that the optical fiber of the fiber output optical path of the optical module breaks, and its invisible light waves may cause harm to the eyes of the operator, and provides a control device and method for the optical module. When the optical fiber of the fiber optic path breaks or is damaged, the harm caused by the reflected light wave can be avoided.

[0046] Such as figure 1 As shown, the control device of the optical module of the embodiment of the present invention is connected to an optical module, and the optical module has an optical power transmitting unit for emitting light waves; the control device includes:

[0047] The first detection module is used to obtain the reflected lig...

Abstract

The invention provides a control device and a method for an optical module and a light emitting device. The control device is connected to the optical module which is provided with a light power emitting unit for emitting light waves. The control device comprises a first detecting module which is arranged for acquiring a reflected light power of the reflected light waves on a damaged side occurred on an optic fiber of the life waves transmitted by the optical module, a second detecting module which is arranged for comparing the reflected light power with a set power threshold value and generating a first comparison result if the reflected light power is more than the power threshold value, and a control module which is arranged for generating a first control signal according to the first comparison result and switching off the light power emitting unit of the optical module according to the first control signal. The technical scheme of the invention can avoid the danger caused by the reflected light waves when the optical fiber on the output optical fiber path of the optical module is broken or damaged.

Description

technical field [0001] The invention relates to the security technology of optical modules in wired optical transmission systems, in particular to a control device, method and light emitting device for optical modules. Background technique [0002] As fiber-to-community and fiber-to-the-home are approaching, the occasions where optical modules are used for short-distance transmission within a city or between cities in a short distance are bound to increase sharply. In order to save system configuration costs, the optical module can be increased. Output optical power, thus eliminating the need for optical amplifiers. But there will be a problem in this way. If the optical fiber of the optical fiber output optical path of the optical module breaks, the invisible light waves may cause harm to the eyes of the operator. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a control device, method and light emitting device...
