![]() The connection types of the fiber tail can be bare fiber or FC/APC. This type of isolators are commonly used in fiber optic communication systems, CATV links, fiber laser and amplifiers. Two 45 offset polarizers are used to construct the isolator device as shown in Figure 1, where the polarization direction of the incident light rotates 45 to. Customer can choose from polarize sensitive or incentive, C band or L band. CASTECH produces in-line isolators with high isolation, high power handling, high return loss, low insertion loss, excellent environmental stability and high reliability, operating in the wavelength range of 850~2000nm and power range of 0.3~500W. The four optocouplers are called the: Photo-transistor, Photo-darlington, Photo-SCR and Photo-triac as shown below. Neptec offers micro-optics isolators that operate in a wide range of wavelength. In applications, this type of isolator is used to maintain the stability of the system's polarization state. It consists of input polarizer, Faraday rotator, half-wave plate or polarizer, output polarizer, and collimators. The polarization-maintaining type can achieve the steady transmittance of linear polarized light and remain the polarization state unchanged. Our Fiber Isolators are available with SM or PM fiber. For more information on differences between types of free-space isolators, see the Isolator Types tab above. It is usually used in the fiber laser system to maintain the stability of optical system effectively. Our Free-Space Isolators are available in fixed and adjustable narrowband options, as well as broadband and tandem options. ![]() The non-polarization-maintaining type consists of birefringent crystals, Faraday rotator, half-wave plate or polarizer, and collimators. In-line isolators can be divided into two categories according to the fiber types: non-polarization-maintaining and polarization-maintaining in-line isolators.
