SUMMARY

The discussion focuses on the attenuation of optical fiber specifically for Fiber Bragg Grating (FBG) sensors operating at a wavelength of 1550nm. It is established that typical attenuation values for optical fibers at this wavelength range from 0.2 dB/km to 0.5 dB/km, depending on the fiber type and quality. The context of the inquiry relates to using FBG sensors for monitoring physiological parameters such as heart and breathing rates. Participants emphasize the importance of selecting appropriate fiber types to minimize signal loss in practical applications.

Welcome to the PF.

What is the context of your question? Is this something from an experiment in your lab? What have you found so far in your research of this question?
 
My seminar topic is fiber Bragg grating sensor used for monitoring heart and breathing rate so related to that it is said that the system will be operating at a Bragg wavelength of 1550nm.
