Overview

The technical specifications of the present invention are applicable to optical fibers with an integrated linear birefringent axis (hereinafter referred to as spun optical fibers) spiral structure as part of the sensing element.

Product Details

Large circular birefringence, highly stable, insensitive to thermal noise and vibration. Suitable for EFOCT, current sensors, and Faraday effect sensors.

Dimension:

`Model`	`1550 nm type optical fiber`	`1310 nm type optical fiber`
`Magneto-optical temperature coefficient` `Sensitivity (linear approximation) ^ 12`	`1. 7x10 ^ -4 1/C (maximum)`	`2.4x10 ^ -4 1/C (maximum)`
