Cutback technique

Figure 6.7 Attenuation spectra of GI POFs based on several polymers measured by the cutback technique.

DMA is measured by the cutback technique under the DML (see Section 6.2). The output optical power from a long fiber is measured while shifting the position of the fiber probe over the input end face then the fiber is cut off a few meters from the input end, and the output power is again measured at this output end of the short fiber while shifting the position of the fiber probe. The attenuation of the individual mode is calculated using Equation 6.10. 

Road paving. This includes bitumen, cutbacks and fluxed bitumen as well as emulsions. Each of these products is subject to very special application techniques. This list is completed by the use of poured asphalt, even though this product is better suited to smaller surfaces sidewalks, courts, etc., than to pavements. Since the middle of the 1980 s, air-blown bitumen is no longer used for road construction. 

Optical losses in the liquid-filled ARROWs are typically measured using the cutback method. This measurement technique assumes optical transmission in the waveguide can be described according to...
