A range of polyimide-coated, bend-insensitive single-mode (SM) fibers with fiber cores that are specifically designed for use in harsh environments. Fiber-targeted microseismic "frac" sensor, distributed temperature and pressure sensor for oil and gas exploration and process optimization. These fibers are also an excellent choice for embedded fiber Bragg grating (FBG) strain and temperature sensor applications.

Polyimide is a high-performance polymer that can withstand short-term temperatures up to 400°C and continuous temperatures of 300°C, enabling fibers to survive high-temperature wells and thermal curing intercalation processes.

Fibers are available in numerical apertures (NAs) ranging from 0.13NA to 0.31 nA. Low NA fibers are designed for low attenuation applications where long fibers are used in straight deployment conditions, such as in distributed temperature sensing (DTS) systems. High NA fibers allow for greatly reduced bending losses in coil deployment states such as in coiled seismic/acoustic sensors.

Advantage:

1. Designed for high temperature applications up to 300°C

2. High NA variant with high NA and minimal bending loss

3. Cladding options for reduced high reliability coils and reduced package size

4. FBG inscription photosensitive core design

1. Downhole sensor

2. Seismograph

3. DTS, Distributed Acoustic Sensing (DAS), Distributed Strain Sensing (DSS) and Distributed Pressure Sensing (DPS)

4. Embedded sensors

5. FBGS

6. Biomedical in vivo sensors

7. High temperature sensor
