Webcurved pillars that make up each tower. The depth of the groove on each pillar is just sufcient to align the ber and hold it with cyanoacrylate adhesive. The pillars are 4mm in length, accommodating a 2mm FBG with a 1mm buffer on either end. It is critical for FBGs to be placed on a straight section of the pillar to avoid double peaks in signal ... WebAug 1, 2024 · The contrast of the FBGs (I, III & V) has virtually no variation in the temperature range of 0–200 °C. When the temperature raises 200 °C to 800 °C, the contrast of the FBGs (I, III & V) gradually decreased, the FBG I decreased by 10 dB and retained 20 dB, FBG III reduced from the 8 dB to 4 dB, and FBG III dropped from 10 dB to 4 dB.
