ஃபைபர் ஆப்டிக் பவர் மீட்டர்

  • ஃபைபர் ஆப்டிக் பவர் மீட்டர் என்பது ஃபைபர் ஆப்டிக் கேபிளின் முடிவில் இருந்து எவ்வளவு வெளிச்சம் வெளிவருகிறது என்பதை அளவிடும் ஒரு சிறப்பு ஒளி மீட்டர் ஆகும்.
  • ஃபைபர் ஆப்டிக் பவர் மீட்டர்கள் ஒளிக்கதிர்களைப் பிடிக்க ஃபைபர் ஆப்டிக் கனெக்டர்கள் மற்றும் உணர்கருவிகளை இணைப்பதற்கான உள்ளீட்டைக் கொண்டுள்ளன.
  • டேட்டாகாம் நெட்வொர்க்குகளில் பயன்படுத்தப்படும் பெரும்பாலான மின் மீட்டர்கள் 850nm மற்றும் 1300nm வேகத்தில் வேலை செய்யும் வகையில் வடிவமைக்கப்பட்டுள்ளன.
  • பவர் மீட்டர்கள் சராசரி ஒளியியல் திறனை அளவிடுகின்றன, உச்ச திறனை அல்ல, எனவே அவை அனுப்பப்படும் தரவுகளின் பயன்  சுழற்சிக்கு உணர்திறன் கொண்டவை.
