Fibercore’s photosensitive (PS) series of fibers have a high germania
For Temperature, Strain and and boron co-doped core composition, enabling high reflectivity gratings
to be written without the need to hydrogen-load. The mode field diameters
Biomedical Sensors and FBGs of the boron co-doped fibers are engineered so gratings may be spliced
into standard telecommunications, or pigtailing fiber with minimal
excess loss.
Fibercore offers a series of high germania SM1500 single-mode fibers
for distributed sensors and splice free sensor arrays. The cores of these
fibers contain more than 5X the germania content of standard
telecommunications fibers. This enables gratings to be written with
or without hydrogen loading, whilst maintaining low attenuation around
1550nm. The addition of polyimide coated versions of these fibers extends
the range, to cover high temperature harsh environment applications.
Typical applications:
• Temperature sensors • 3D shape sensing
• Strain sensors • Pressure sensors
• Biomedical sensors
