Abstract
The invention provides a method for detecting an optical fiber link state. Specifically, an optical fiber module is used for receiving signals to detect the optical fiber link state.
Description
Technical field
The present invention is whether a kind of detection fiber network links correct method.
Background technology
Along with popularizing of network, the application limitation of twisted-pair wire net has had a strong impact on the scope of network topology, and the maturation along with optic fibre manufacture process, its cost further reduces, more and more remote, middle distance all adopts centralized optical fiber wire laying mode, so that the application of fiber plant trends towards low cost, portable development.
Usually the optical fiber module also provides an independently input pin except independently sending, receive signal pair, is used to indicate the linking status of optical fiber, but needs to adopt special-purpose pin input.And the invention provides a kind of method by reception input fiber optic links state, and further improved the integrated level of chip, realized the more requirement of miniaturization.
Summary of the invention
A kind of fiber optic links condition detection method, the method may further comprise the steps: right signal access link detection module is received in the optical fiber mode winding; Optical fiber is received right input signal detect the fiber optic links state that obtains.
Description of drawings
In claims of present patent application, pointed out particularly theme of the present invention, and clearly it has been proposed patent protection.Yet with reference to following detailed description and accompanying drawing, the related structure that can better understand the present invention and implementation method with and purpose, Characteristics and advantages.
Fig. 1 is the theory diagram of fiber optic links state detection module.
Fig. 2 is the state machine of fiber optic links state detection module.
Embodiment
In the following detailed description, having described specific details comprehensively understands the present invention in order to provide.Yet the professional and technical personnel will appreciate that the present invention also can implement with other similar details.
A kind of fiber optic links condition detection method comprises 3 modules as shown in Figure 1, wherein 201 is input, network signal or noise signal for detection of input signal, 202 be used for to determine the time for timer, 203 is the master control logic state machine, and the signal that detects is judged and definite fiber optic links state.
Operating state in conjunction with state machine shown in Figure 2, state machine 203 enters link off-state 302 after initial condition 301,201 modules detect the signal of input, level by signal changes judges it is effective fiber data or noise or without input, if effective fiber data, and after reaching 10uS by timer 2 02, state machine 203 enters link success status 303; If the effective fiber data that 201 modules detect fails to keep 10uS, then state machine 203 still is in link off-state 302, and timer resets.After state machine 203 entered link success status 303,201 modules continued the signal of input is detected, if fail to detect effective fiber data, and after reaching 10uS by timer 2 02, state machine 203 enters link off-state 302; If the undetected effective fiber data of 201 modules fails to keep 10uS, then state machine 203 still is in link success status 303, and timer resets.
Although herein declarative description some feature of the present invention and a kind of implementation method, for the professional and technical personnel, many modifications, replacement, variation and equivalent substitution will appear.Therefore, protection scope of the present invention is as the criterion with the scope of appended claim.
Claims (1)
1. fiber optic links condition detection method, the method may further comprise the steps: right signal access link detection module is received in the optical fiber mode winding; Optical fiber is received right input signal detect the fiber optic links state that obtains.
