94-Gb/s 4-PAM Using an 850-nm VCSEL, Pre-Emphasis, and Receiver Equalization

We present the results from an experimental demonstration of a 100-Gb/s 4-PAM transmission over a few meter MMFs using an 850-nm VCSEL with both analog pre-emphasis and a digital offline equalizer. The effective data rate is 94 Gb/s after accounting for the forward error correction overhead. Digital equalizers of lengths 11 to 71 taps were investigated.
