The technical specifications of the present invention are applicable to optical fibers with an integrated linear birefringent axis (hereinafter referr
Product details
Large circular birefringence, highly stable, insensitive to thermal noise and vibration. Suitable for EFOCT, current sensors, and Faraday effect sensors.
Dimension:
Note:
The temperature range is -60 ° C to+60 ° C.
2. Parameter measurement is based on the standard current measurement results of laboratory optical fibers.
3. The current transformer adopts the studied spun optical fiber as the sensing element.
