Konferensbidrag (refereegranskat)abstract
- We demonstrate 44 Tb/s transmission using three 50x24 Gbaud PM-256QAM comb-based superchannels. Each superchannel combines a single optical pilot tone with individual digital pilot symbols to minimize the total overhead, enabling record spectral-efficiency over the full C-band.

Efficient Offline Evaluation of FEC Codes Based on Captured Data with Probabilistic Shaping

Konferensbidrag (refereegranskat)abstract
- We propose a tool for reusing experimental or simulation data of probabilistically shaped signals with different FEC codes. A single recorded histogram of log-likelihood ratios is sufficient to examine arbitrary coding at low BERs.

Technologies toward implementation of probabilistic constellation shaping
- 2018
-
Ingår i: European Conference on Optical Communication, ECOC. ; 2018-September
-
Konferensbidrag (refereegranskat)abstract
- Reverse concatenation of forward error correction and distribution matching significantly improves the implementation capability of probabilistic constellation shaping. However, to take full advantage of the benefits, one should carefully understand the practical aspects and trade-offs.
