Standard Multimode couplers:

FONT's Standard Multimode Couplers are fabricated from graded index fibers with core diameters of 50um or 62.5um. 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 (400nm to 1310nm) with uniform modal power distribution launch condition. 

Large core fiber couplers:
FONT's Specialty Multimode Couplers are manufactured from variety of fibers with core diameters of 100um, 200um, 400um. These couplers are widely used in laser power delivery, sensor technology and laboratory test and measurements.
FONT's Multimode couplers are available in  variety of package styles to meet specific requirements.
