Embodiment 1

[0027] This embodiment discloses a method for judging the mixture of BOSA devices, which includes the following steps:

[0028] Step 1: First replace the variable resistance of the Huygens DC bridge with a fixed resistance, and then set up a microprocessor MCU with a differential signal digital-to-analog converter. The model of the microprocessor MCU can be C8051F320 with a USB interface. , Which includes ADC+ and ADC- two ADC sampling terminals, and then connect the ADC sampling terminal of the differential signal digital-to-analog converter to the two arms of the Huygens DC bridge. After connection, the microprocessor MCU can directly obtain the differential The sampling value of the signal digital-to-analog converter;

[0029] Specifically, the resistance of the replaced fixed resistance is the same as the resistance of the two fixed resistances included in the Huygens DC bridge itself. The resistance of the three fixed resistances is taken from the OUTP pin to the GND pin of th...

Abstract

The invention discloses a mixing discrimination method of a BOSA device. The method comprises the following steps of 1, firstly, replacing a variable resistor of a Huygens direct-current bridge with afixed resistor, then arranging a microprocessor MCU internally provided with a differential signal digital-to-analog converter, and respectively connecting ADC sampling ends of the differential signal digital-to-analog converter to intersection points of two arms of the Huygens direct-current bridge, 2, enabling an OUTP pin and a GND pin of the BOSA device to be inserted into the two ends of a measured resistor, and conducting sampling to obtain a sampling value, and 3, comparing the sampling value with a preset threshold value by the microprocessor MCU, and judging the type of the BOSA device according to a comparison result. According to the method, the GPON OLT BOSA device and the EPON OLT BOSA device can be quickly distinguished at low cost, and the risk caused by material mixing is greatly reduced.

Description

Technical field [0001] The present invention relates to the technical field of optical modules, in particular to a method for judging the mixture of BOSA devices, and in particular to a method for judging the mixture of GPON OLT BOSA devices and EPON OLT BOSA devices. Background technique [0002] Since the core components of the GPON OLT BOSA device and EPON OLT BOSA device are composed of 2.5G LD TOCAN+1.25G APD-TIA TOCAN, the accessories, dimensions, colors, etc. can be exactly the same, and they cannot be distinguished from the naked eye. Once the two BOSA devices are mixed in the production line, it will have a huge impact on the performance of the finished optical module. This is because the 1.25G TIA chip built in TOCAN, the model used by GPON OLT and EPON OLT are completely different. Although it is known that if the GPON OLT BOSA is implemented as an ERON OLT optical module, it can basically meet the index requirements of the ERON OLT optical module specification; but if...
