Short-Length FBG

Alxenses’s short-length FBG is fabricated based on advanced FBG fabrication technique and production facilities. The Bragg wavelength and length of the FBG can be controlled precisely while maintaining high reflectivity and side-lobe suppression ratio.

The standard length of short-length FBG is 3mm and can be customized to various lengths upon request. The short-length FBG allows smaller form-factor housing to be used for FBG packaging that is necessary when sensor size is a concern. Short-length FBG is suitable for building small sensors for temperature and strain measurements and compact sensor arrays for distributed monitoring applications.

Features:
•Short length
•Low insertion loss
•Multiplexing of FBG sensors in single fiber

Applications:
•Small form-factor sensor packaging


Note:

In general, the bandwidth becomes wider when the length of FBG gets shorter.
