• Mode independent behavior in multimode fiber applications.

Two-by-two polarizing beam splitter for 1550nm with 50dB return loss. Both inputs are Corning SMF-28 singlemode fibers, and both outputs are 8/125 polarization maintaining fibers for 1550nm. All four fibers are one meter long, 900 micron OD cabled, with no connectors on the fiber ends. The output polarization extinction ratio is better than 25dB.
