A 4-λ, 40Gb/s/λ bandwidth extension of multimode fiber in the 850nm range

View publication


The bandwidth capacity of 50/125 μm multimode fiber is extended by using four VCSELs with wavelengths coarsely separated at 30nm and with each wavelength operating at 40Gb/s. All four wavelengths achieve BER < 1E-12 at 100m.
