Mode Field Adaptor (MFA) - Backward version

This 1×1 Mode Field Adaptor is designed for high power fiber laser application.It connects two different fibers with different NA and core diameter, as well as cladding, to keep mode field diameter matched with low fundamental mode signal loss and minimal degradation of beam quality (M2).Fiber types can be customized.


Key Features

* High Signal Transfer Efficiency

* Low Degradation of Beam Quality

* Wide Wavelength Range Applicable

* Customized Configurations Available
