Error-Free 100Gbps PAM-4 Transmission Over 100m OM5 MMF using 1060nm VCSELs

We experimentally demonstrate error-free (BER <;10
^-12
) rates beyond 100Gbps over 100m OM5 using unpackaged 1060nm VCSELs. Power penalties of PAM-2/PAM-4 are examined demonstrating OM5 fiber capacity to support wavelengths to 1060nm with only transmitter equalization.
