Test system for automatically calibrating power factor of semi-active CWDM module

Abstract

The invention discloses a test system for automatically calibrating a power factor of a semi-active CWDM module, which comprises the following steps: firstly, issuing an instruction through software to ensure that a PRI path is conducted, and turning on all 18 paths of light sources of a CWDM light source module, wherein the method comprises the specific operation steps that the optical power of an optical power channel 1 is read through an optical power meter, and the output optical power W1 of a 1*12 optical switch channel 1 is calculated according to the splitting ratio of an optical splitter and the insertion loss of a 1*12 optical switch; inputting an instruction through a serial port of the PC, and obtaining ADC voltage values Vp1 and V1 of the DUT according to an ADC reading position and register position map of each wave band in the PC; and automatically calibrating the power factor, wherein manual calibration is not needed, and the method has the advantages of being efficient, rapid, easy to operate, high in passing rate and the like, and therefore, the production efficiency is greatly improved, and the calibration time is shortened.

Description

Problems solved by technology

[0002] With the shortage of pipeline resources in national strategic cities, the scenarios for laying optical cables are gradually limited; in areas where optical cables are scarce, there will be no pipeline resources or scenarios where optical cables cannot be laid; Long time and large investment; due to municipal coordination, pipeline construction, and pipeline laying, the time period for optical cable scheduling is long, the communication cost is high, and the cost of optical cable laying is higher than the cost of fronthaul equipment; Practical problems of difficult and expensive household registration; at present, indoor distribution construction needs to be communicated with the customer's property department, and there are problems such as long time, slow opening of the station, and expensive fees; in this case, the CWDM module with OLP function can be very good It solves the above-mentioned problems of 5G network, and solves the problems of large number of fronthaul network laying and difficult maintenance in the later stage. It is also the most effective solution for fronthaul network that comprehensively considers fiber saving, low cost and controllability.

[0003] However, the existing CWDM module power factor calibration is still at the stage of manual calibration. Manual calibration takes a long time, has low efficiency and poor accuracy, so it is necessary to improve it.
