Abstract
Data logging at temperatures up to 200.degree. C. by optical signals sent via a 'wet' optical fiber is achieved by using as a light source device an LED having a peak amplitude wavelength at ambient temperature which is sufficiently removed from 1390 .ANG. so that acceptable transmission levels can pass through the fiber when the wavelength/temperature shift of the LED is allowed for.
