A METHOD FOR PROTECTING PHOTOELECTRICITY INTEGRATED DEVICE AND PHOTOELECTRICITY INTEGRAGED DEVICE

摘要

The present invention provides an optoelectronic integrated apparatus and method for protecting optoelectronic integrated apparatuses. The method includes: setting one or more spare wavelength-tunable optical source links and corresponding spare data channels in an optoelectronic integrated apparatus; detecting whether each working optical source link in the apparatus at the transmitting end is malfunctioning; and selecting a spare wavelength-tunable optical source link and a corresponding spare data channel to transmit service data for a malfunctioning working optical source link and the corresponding working data channel when detecting that the working optical source link is malfunctioning. The apparatus includes: a protection control unit, pluralities of working optical source links and corresponding working data channels, and one or more spare wavelength-tunable optical source links and corresponding spare data channels. The present invention provides protection for the optoelectronic integrated apparatuses, thus enhances the reliability of the optoelectronic integrated apparatuses without increasing the maintenance cost.
