Demonstration of a 160-Gbh Group-Alternating Phase CSRZ format Featuring Simplified Clock Recovery and

We propose and demonstrate a new 160-Gbh signal format employing phase inversion of every four consecutive bits in a group. This format enables simple clock recovery by spectral filtering, and increases the nonhear tolerance compared to CSRZ signals.
