Konferensbidrag (refereegranskat)abstract
- We report record error-free data transmission of 40Gb/s over a 1m-long multimode polymer spiral waveguide. The waveguide imposes no significant transmission impairments in the link despite its highly-multimoded nature and long length, demonstrating its potential in high-speed board-level optical interconnections.

Fast and simple fault monitoring for long-reach passive optical networks
- 2014
-
Ingår i: 2014 European Conference on Optical Communication, (ECOC). - : IEEE. - 9782954944401 ; , s. 6964070-
-
Konferensbidrag (refereegranskat)abstract
- We propose a fast and simple monitoring system based on multi-wavelength bi-directional transmission reflection analysis approach for long-reach passive optical networks. Both experimental and simulation results have demonstrated the proposed system can reach high accuracy for fault localization.

Bandlimited Power-Efficient Signaling for Intensity Modulation
- 2014
-
Ingår i: European Conference on Optical Communication, ECOC 2014; Cannes; France; 21 September 2014 through 25 September 2014. - 9782954944401
-
Konferensbidrag (refereegranskat)abstract
- A new, power-efficient signaling method for intersymbol interference-free transmission over the bandlimited intensity-modulation direct-detection channel is proposed. The method utilizes pulse-amplitude modulation with a sinusoidal bias function and is more power-efficient than previously known methods.

Comparison between Coherent Superposition in DSP and PSA for Mitigation of Nonlinearities in a Single-span Link
- 2014
-
Ingår i: European Conference on Optical Communication, ECOC 2014; Cannes; France; 21 September 2014 through 25 September 2014. - 9782954944401 ; , s. Art. no. 6964015-
-
Konferensbidrag (refereegranskat)abstract
- An experimental comparison is made between nonlinearity mitigation through coherent superposition optically in a phase-sensitive amplifier and electrically in DSP. The improved nonlinear tolerance is quantified in terms of EVM with high received power and sensitivity with high launch power.

Experimental comparison of PS-QPSK and LDPC-coded PM-QPSK with equal spectral efficiency in WDM transmission
- 2014
-

-
Konferensbidrag (refereegranskat)abstract
- We compare QPSK with a rate 0.75 LDPC-code and PS-QPSK, which have the same spectral efficiency, in long-haul WDM transmission. We show that LDPC-coded PM-QPSK can achieve up to 98% increased transmission distance over uncoded PS-QPSK at BER = 10-3.

Comparison of Terminated and Tailbiting Spatially Coupled LDPC Codes With Optimized Bit Mapping for PM-64-QAM
- 2014
-
Ingår i: 2014 European Conference on Optical Communication, ECOC 2014; Cannes; France; 21 September 2014 through 25 September 2014. - 9782954944401 ; , s. Art. no. 6964047-
-
Konferensbidrag (refereegranskat)abstract
- We optimize the allocation of coded bits to modulation bits for spatially coupled low-density parity-check (SC-LDPC) codes and PM-64-QAM. Tailbiting SC-LDPC codes are shown to offer a similar gap to capacity as their terminated counterparts, at a lower FEC overhead.

On Maximum Likelihood Sequence Detectors for Single-channel Coherent Optical Communications

-
Konferensbidrag (refereegranskat)abstract
- Two different detectors that account for the nonlinear signal–noise interaction in a single channel coherent optical link are compared. The results indicate that accounting for the correlation between the samples leads to improved performance over stochastic digital backpropagation.

Phase-Sensitive Amplification and Regeneration of Dual-Polarization BPSK without Polarization Diversity

-
Konferensbidrag (refereegranskat)abstract
- We analyze the performance of a degenerate vector PSA-based receiver and compare to an EDFA-based receiver, achieving an about 1 dB sensitivity improvement. We also assess the phase regeneration provided by the vector PSA when the signal phase is degraded.

Single parity check multi-core modulation for power efficient spatial super-channels
- 2014
-

-
Konferensbidrag (refereegranskat)abstract
- We investigate multi-core modulation formats for spatial super-channels using a single parity check on PDM-QPSK symbols. Compared to per-core PDM-QPSK, we show improvements in required OSNR of up to 1.8 dB, with minimal impact on spectral efficiency.
