Polarization Maintaining Fiber Pigtail
|
(PMFP Series)
The PM Fiber Pigtail is the basic building block for PM fiber optics components.
The Fiber Pigtail is characterized with fine polishing surface, accurate polishing angle and high
extinction ratio. The unique processing and high quality AR coating enable the fiber pigtail to handle
high power with minimum loss.
