Title:
BURR REMOVING METHOD AND APPARATUS FOR OPTICAL SIGNAL LOSS SIGNAL
Document Type and Number:
WIPO Patent Application WO/2016/074350
Kind Code:
A1
Abstract:
The present invention provides a burr removing method and apparatus for an optical signal loss signal. The present invention adopts the technical solution of: when detecting that an online signal output by an optical module changes from a high level to a low level, setting the online signal to the high level and starting a timer; when detecting that the online signal output by the optical module changes from the low level to the high level, setting the online signal to the high level and resetting the timer; and when the time of the timer reaches a preset time, setting the online signal to the low level, wherein when the online signal is set to the high level, an optical signal loss signal of the optical module fails. In this way, additional burr filtering is not required, the problem of time delay in a burr removing method for an optical signal loss signal of an optical module is effectively solved, and the time delay generated during removal of burrs of the optical signal loss signal of the optical module is avoided.
