Description

一种高精度光纤余长测量装置A high-precision optical fiber excess length measuring device 技术领域Technical field
本发明涉及光纤余长测量技术领域，涉及一种高精度光纤余长测量装置。The invention relates to the technical field of optical fiber excess length measurement, and relates to a high-precision optical fiber excess length measurement device.
背景技术Background technique
在光缆产品中，光纤余长一直是一个很重要的参数指标，直接影响到光缆产品生产加工中光纤的衰减性能以及光缆产品架设使用性能稳定性和寿命。因此在光缆产品加工时光纤余长加工控制的精准性能体现出生产工艺控制的能力。目前行业内光缆中光纤余长测量方式采用余长测量平台和钢直尺作为测量工具，目前使用钢直尺测量光纤长度不满足余长测量精度要求，同时余长测量平台无法对被测光缆产品或光单元进行校直、使用剪刀剪取被测光缆产品或光单元进度不足、光纤测量存在斜拉对不齐等因素，导致现有余长测量平台未通过MSA实验(有效分辨率NDC＝2、％公差Tolerance＝94.2)。如果光纤余长测量和控制不准确将对产品加工制造、架设安装和使用带来很大的负面影响，甚至会导致信息通信的突然中断。In optical cable products, the excess length of the optical fiber has always been a very important parameter index, which directly affects the attenuation performance of the optical fiber in the production and processing of the optical cable product, and the stability and service life of the optical cable product. Therefore, the precise performance of optical fiber excess length processing control during the processing of optical cable products reflects the ability of production process control. At present, the optical fiber excess length measurement method in the industry uses the excess length measurement platform and the steel ruler as the measuring tool. The current use of the steel ruler to measure the length of the fiber does not meet the accuracy requirements of the excess length measurement, and the excess length measurement platform cannot be used to measure the optical cable product under test. Or the optical unit is straightened, scissors are used to cut the measured optical cable product or the progress of the optical unit is insufficient, and the optical fiber measurement has misalignment in the diagonal pull, which causes the existing excess length measurement platform to fail the MSA experiment (effective resolution NDC = 2, % Tolerance = 94.2). If the measurement and control of the excess length of the optical fiber are inaccurate, it will have a great negative impact on the manufacturing, erection, installation and use of the product, and even cause the sudden interruption of information and communication.

通过集成切料组件和检测组件，可确保一次样品裁剪即满足标准样品长度要求，减少了光单元裁切和测量分别操作的时间，提高测量精度，同时为减少光单元及其内部光纤不同时测量的误差，采用切料台2上的切料槽21加切割部件来实现光单元(光纤)样品裁剪和测量一步完成，并满足样品裁切标准长度要求，同时使用测量卡尺测量光纤超出光单元样品的长度，这样大大降低了分别测量光单元和光纤的测量误差，缩短检测时间，提高余长测量的准确性和精确度。Through the integration of the cutting component and the detection component, it can ensure that the standard sample length requirement can be met once the sample is cut, which reduces the time of the optical unit cutting and measurement operations, improves the measurement accuracy, and reduces the optical unit and its internal optical fiber at the same time. The cutting groove 21 on the cutting table 2 and the cutting parts are used to realize the cutting and measurement of the optical unit (optical fiber) sample in one step, and meet the standard length requirements of sample cutting.
