PM Isolator

It is an optical device designed for polarisation-sensitive optical systems, combining the unidirectional transmission characteristics of an optical isolator (Isolator) with the polarisation-maintaining capability of Polarization-Maintaining (PM) technology. Its core function is to allow forward light to pass through while blocking reflected light in the reverse direction and ensuring that the polarisation of light (e.g. linear polarisation direction) does not change.

*Above specifications are for devices without the connectors.

*For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, and ER will be 2dB lower.

*The PM fiber and the connector key are aligned to the slow axis. And for F type, fast axis is blocked, for type B ; both axis is working
