There are a wide variety of optical isolator, including on-line optical isolators, free space optical isolators, etc. We provide various specifications of optical isolators to meet the needs of different applications.The internal design of 1310/1480/1550nm polarization-independent optical isolator is aimed at the separate processing of two orthogonal polarization states in single-mode fiber to ensure the polarization-independent characteristics of the whole device.Monopole devices with low insertion loss and double stage devices with high optical isolation are suitable for different applications, mainly for fiber amplifiers, fiber lasers, fiber CATV networks and satellite communications. Opelink Provide Single & dual stage optical Faraday isolators, Custom Isolator Available, High Reliability and Stability, welcome to inquire.
