The Limits of Digital Backpropagation in Nonlinear Coherent Fiber-Optical Links
- 2012

Ingår i: 2012 38th European Conference and Exhibition on Optical Communications, ECOC 2012; Amsterdam; Netherlands; 16 September 2012 through 20 September 2012. - 9781557529503 ; , s. Art. no. 6706029-
-
Konferensbidrag (refereegranskat)abstract
- The performance of a single-channel fiber-optical link is evaluated with linear (dispersive) and nonlinear equalization. The results show a quadratic growth of the noise variance with input power for a system with nonlinear equalization and also justify the known cubic growth for linear equalization.

Brillouin Suppressed Highly Nonlinear Fibers
- 2012
-
Ingår i: European Conference and Exhibition on Optical Communication, ECEOC 2012; Amsterdam; Netherlands; 16 September 2012 through 20 September 2012. - 9781557529503 ; , s. We.1.F.1-
-
Konferensbidrag (refereegranskat)abstract
- Methods for suppression of stimulated Brillouin scattering in highly nonlinear fibers are reviewed. Emphasis is paid to SBS suppression by aluminum doping of the core. New results for a HNLF with an aluminum doped core and reduced loss are presented.

-
Konferensbidrag (refereegranskat)abstract
- Using an improved receiver-side spectral shaping technique, we successfully transmitted 1.936 Tb/s (11×176 Gb/s) DP-16QAM superchannel signal over 8 × 80 km EDFA-only SSMF and two 280 GHz WSSs in support of future 1.6 Tb/s Ethernet with up to 20% FEC overhead.

Optimized lattice-based 16-level subcarrier modulation for IM/DD systems
- 2012
-
Ingår i: 2012 38th European Conference and Exhibition on Optical Communications, ECOC 2012; Amsterdam; Netherlands; 16 September 2012 through 20 September 2012. - 9781557529503 ; , s. Art. no. 6705904-
-
Konferensbidrag (refereegranskat)abstract
- We present an experimental demonstration of an optimized 16-level lattice-based single-cycle subcarrier modulation for IM/DD systems at 10 Gbps. The new format has 2.5 dB better sensitivity than single-cycle subcarrier 16-QAM and up to 1 dB better sensitivity than baseband 4-PAM at the same bit rate.
