Какви са ефектите на температурата върху формата на вълната на оптични влакна
Optical fiber waveform has a significant impact on the performance of an optical transmission system, особено при високи температури. Общо взето, optoelectronic devices such as transceivers and amplifiers suffer from increased noise and shorter life when exposed to higher operating temperature ranges. This is because hot beams excite more modes in the crystal structure of silicon carbide than cold beams do.
The effects of temperature also go beyond just transceiver and amplifier performance; they can also have an adverse effect on signal integrity through the entire fiber-optic infrastructure. Поради тази причина, OSU scientists developed a mathematical model that takes into account all relevant parameters – including substrate material properties (e.g., rate saturation), electric fields near dielectrics (т.е., splitting losses), cladding characteristics (e.g., mode field intensity) – in order to predict total chanagement degradation under various conditions with accuracy well above 90%.
Higher temperatures also cause distortion of light waves due to their elasticity properties, which can create visual errors such as jagged edges or moire patterns. Освен това, high temperatures may increase bit error rate (BER) values and even lead to data corruption in some cases.
While there are many factors that affect optical fiber waveform at different frequencies, it’s important to keep in mind that temperature is one of them and should be taken into account when planning future infrastructure projects or deployments.
