The invention discloses a multi-channel chip aging method which comprises the following steps: setting initial parameters including aging temperature, aging time and body dark current; aging the multi-channel chip to obtain initial voltage and initial current of the multi-channel chip in a normal temperature state; obtaining the reverse bias voltage of the aged multichannel chip and the time required for reaching the body dark current; based on the initial voltage, the initial current, the reverse bias voltage and the time required for reaching the body dark current, determining the aging effect of the multi-channel chip, and the problems that in the prior art, batch aging of APD chips is difficult to achieve, APD chips in a special packaging form are aged, and the service life of the APDchips is shortened are solved. The technical problem that different pins are powered on and inconsistent when a bare chip is directly aged is solved, batch aging of APD chips of different packaging forms is achieved, meanwhile, the production cost and difficulty are reduced, the aging time can be adjusted in real time, and the aging effect accuracy of the chip is improved.
Description
Technical field [0001] The present invention relates to the field of fiber optic communications, and more particularly to a multi-channel chip aging system and method. Background technique [0002] The ROSA (Receiver Optical Subassembly, Light Receiver) of the optical fiber communication is mainly used to convert the optical signal into an electrical signal. The core device of the optical module is a light emission and a light receiving device, in order to make the designed optical device during operation. Stable, the light-devices are subjected to a certain amount of time long before formally putting it, and the defective device, the chip is filtered in advance, and the lattice of the chip or device is stable, and the performance reaches a steady state. The chip aging of the optical device is mostly based on the emitting light chip, and the receiving optical chip is often less aging due to the overall process. Among them, since the APD (Avalanche PhotoDioDe, avalanche diode) chi...
