Multimode Fiber Coupler
Flyin Optronics’ Multimode Fiber Optic Coupler(MM FBT Coupler ) are fabricated from multimode fibers with core diameters of 50um ,62.5um or 100um. Standard multimode couplers are commonly used in short distance communications with LED sources operating at 1310nm or 850nm. Multimode couplers are wavelength independent over a broad range of wavelengths (600nm to 1610nm) with uniform modal power distribution launch condition, multimode tree/star couplers NX4(n=1,2,4) NX8(n=1,2,8) NX16(n=1,2,16) port ratios are available.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
