Product description:

In-line isolators can be divided into two categories according to the fiber types: non-polarization-maintaining isolator and polarization-maintaining isolator.

The non-polarization-maintaining isolator consists of birefringent crystal, Faraday rotator, half-wave plate or polarizer , and collimator. It’s usually used in the fiber laser system and to maintain the stability of optical system effectively.

The polarization-maintaining isolator is a laser component that can achieve the steady transmission of linear polarized light and remain the polarization state unchanged. It consists of input polarizer, Faraday rotator, half-wave plate or polarizer, output polarizer, and collimator. In some special applications, this type of isolator is used to maintain the stability of the system’s polarization state.

CASTECH's in-line isolators are with high isolation, high power handling, high return loss, low insertion loss, excellent environmental stability and reliability, operating in the wavelength range of 850nm-2000nm and power range of 0.3W-500W. The connection types of the fiber tail can be adopted by bare fiber, FC/PC or FC/APC.

 

Applications:

● EDFA

● DWDM Systems

● Optical coherence detection

● Laser sensing

● Fiber communication etc
