A theoretical foundation for any turbo interleaver to be a contention-free interleaver to access data in parallel by a butterfly network is presented. A contention-free parallel access of multiple ...

We experimentally demonstrate optical generation of a super-channel of 7 × 12.5 Gbaud QPSK-modulated subcarriers at Nyquist spacing, using a flat-top interleaver. The interleaver comprises a ...
