In this chapter, the wavelength dependence of bend loss in a step-index multimode optical fiber (100 µm core diameter; fused silica) was investigated for fiber bend radii ranging between 2.0 and 4.5 mm using six laser excitation wavelengths, namely, 337.1, 470, 590, 632.8, 750, and 810 nm. The results obtained from fitting the bend loss measurements to Kao's model and utilizing MATLAB® indicate that bend loss is wavelength dependent and transmission loss in multimode optical fibers increases with the decrease in the fiber bend radius. Furthermore, the response of a microbend fiber-optic displacement sensor was characterized at 337.1, 470, 632.8, 750, and 810 nm. Measurements obtained from the microbend sensor indicate that the sensor output power is linear with the applied displacement and the sensor output is wavelength dependent. Lastly, references for industrial and biomedical applications of microbend fiber-optic sensors are provided. Finally, a brief description for the transmission loss mechanisms in optical fibers is given.

In this work, a single-stage C-band erbium-doped fiber amplifier (EDFA) has been constructed and characterized. Gain (G) and noise figure (NF) measurements collected for the C-band EDFA as a function of wavelength (1528.8 to 1562.3 nm) and laser pump powers are discussed. Further, the EDFA conversion efficiency (CE) as a function of laser pump powers is presented. Simplified mathematical expressions for the EDFA gain, NF, and CE are provided. The C-band EDFA signal gain remained flat in the spectral region 1539 to 1562 nm. Moreover, the C-band EDFA NF increased with wavelength and decreased with the 1480 nm laser pump powers. Additionally, the C-band EDFA maximum achieved conversion efficiency and signal gain is 22.64% at P1=19.49 mW and 22.6 dB at 1531.1 nm, respectively.
