Multimode Fiber Optic Couplers
Multimode Fiber Optic Coupler(MM FBT Coupler ) are fabricated from Corning’s 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.
Features
