As a relatively precise instrument, fiber optic splitters may also encounter some problems during use. This article summarizes the occasional difficulties encountered in daily use and their solutions
1, Insertion loss issue
The insertion loss of a fiber optic splitter refers to the ratio of the output optical signal intensity after the input optical signal passes through the splitter to the input optical signal intensity. The issue of insertion loss can lead to a shorter transmission distance, affecting overall transmission performance. The main reasons for the high insertion loss include internal absorption, reflection, scattering and other losses in the splitter, as well as uneven ports and loose connections in the splitter.
Solution: Choose a low insertion loss splitter, keep the splitter port clean and tightly connected, reduce connector loss and scattering loss, etc.
2, Spectral uniformity issue
The spectral uniformity of a fiber optic splitter refers to the distribution of optical signal intensity at each output port. If the spectral uniformity is poor, it will affect the overall transmission performance. The main reason for the problem of spectral uniformity is due to factors such as manufacturing errors and temperature changes in optical components, resulting in optical component displacement, attenuation, etc.
Solution: Choose a spectrometer with stable performance, select a spectrometer with high precision optical components, and regularly maintain and clean the spectrometer.
3, Temperature stability issue
The temperature stability of a fiber optic splitter refers to its performance changes at different temperatures. If the temperature stability is poor, it will lead to a decrease in the performance of the spectrometer, affecting the overall transmission performance. The main reasons for temperature stability issues include changes in refractive index caused by temperature fluctuations, and displacement of components caused by thermal expansion and contraction.
Solution: Choose a spectrophotometer with good temperature stability, regularly maintain and clean the spectrophotometer, and take insulation measures.
4, Port contamination issue
Port contamination of fiber optic splitters can lead to a decrease in transmission performance. The main reason for port contamination is due to impurities such as dust, water vapor, and harmful gases entering the port, resulting in an unclean port surface.
Solution: Keep the splitter port clean, perform regular maintenance and cleaning, and use protective measures such as dust covers.
5, Reliability issues
The reliability of a fiber optic splitter refers to its stability and durability during long-term use. If the reliability is poor, it will lead to a decrease in the performance of the splitter, affecting the overall transmission performance. The main reasons for reliability issues include aging of internal materials in the spectrometer, wear and tear of optical components, and erosion from environmental factors.
Solution: Choose a reliable splitter, perform regular maintenance and upkeep on the splitter, take effective protective measures, and ensure a suitable operating environment.
