Demonstration of a 71.8 Gbps 4-PAM 850 nm VCSEL-based Link with a Pre-emphasizing Passive Filter

摘要

We present 71.8 Gbps 4-PAM back-to-back transmission in an 850 nm VCSEL-based link using a passive pre-emphasis filter and FEC with no post-equalization. Bit error rates below 10~(-8) are demonstrated with 72 Gbps uncoded data.
