Energy-Efficient Soft-Decision LDPC FEC for Long-Haul Optical Communication
- 2015
-
Ingår i: 41st European Conference on Optical Communication, ECOC 2015, Valencia, Spain, 27 September - 1 October 2015. - 9788460817413
-
Konferensbidrag (refereegranskat)abstract
- We present forward error correction systems based on a low complexity LDPC decoding algorithm and randomly-structured LDPC codes. Simulation and ASIC synthesis results show throughput and net coding gain sufficient for long-haul applications, with greatly reduced energy consumption.

Four-Dimensional Estimates of Mutual Information in Coherent Optical Communication Experiments
- 2015
-
Ingår i: European Conference on Optical Communications (ECOC), Valencia, Spain, 27 September - 1 October 2015. - 9788460817413
-
Konferensbidrag (refereegranskat)abstract
- Mutual information is experimentally investigated for long-haul coherent transmission. Receivers that consider memoryless four-dimensional noise distributions can achieve significantly higher rates than receivers assuming two-dimensional symmetric distributions.

A path to use large linewidth LO in 28 Gbd 16-QAM metro links
- 2015
-
Ingår i: European Conference on Optical Communication, ECOC. - : IEEE. - 9788460817413
-
Konferensbidrag (refereegranskat)abstract
- We experimentally investigate the possibility to mitigate local oscillator induced Equalization Enhanced Phase Noise penalty. The results pave the way for the use of even 10 MHz linewidth local oscillator lasers in 28 Gbd 16-QAM metro links.

Sensitivity improvements in an 850 nm VCSEL transmitter using a one-tap pre-emphasis electronic filter
- 2015

Konferensbidrag (refereegranskat)abstract
- We present ISI reduction of an 850 nm VCSEL-based back-to-back optical link using a one-tap electronic pre-emphasis filter and compare it to a VCSEL link without filtering with similar launch conditions. Error floors are eliminated by the use of the filter.

Optimum detection in presence of nonlinear distortions with memory

-
Konferensbidrag (refereegranskat)abstract
- The performance of nonlinearity-tailored detection for single channel, single span optical fibre systems is studied. Monotonically decreasing bit error rate with transmitted power can be achieved without any nonlinearity compensation.

-
Konferensbidrag (refereegranskat)abstract
- We demonstrate frequency-comb regeneration from two received unmodulated carriers usinga parametric mixer. For 10 dB optical signal-to-noise ratio of the unmodulated carriers, up to 60 carriersare generated without linewidth degradation.

Ingår i: 41st European Conference on Optical Communication, ECOC 2015, Valencia, Spain, 27 September 2015 - 1 October 2015. - 9788460817413
-
Konferensbidrag (refereegranskat)abstract
- We analyze the power consumption in hybrid EDFA/Raman amplified links along with the trade-off of span distance and the use of FEC. A simple model provides some guidelines for the choices to be made.

Manycast and anycast routing for replica placement in datacenter networks
- 2015
-
Ingår i: European Conference on Optical Communication, ECOC. - : Institute of Electrical and Electronics Engineers (IEEE). - 9788460817413
-
Konferensbidrag (refereegranskat)abstract
- Inter-datacenter networks need to support datacenters communication with the end-users, as well as content replication and synchronization between datacenters. This paper presents an integrated routing and replica placement strategy for WDM inter-datacenter networks resulting in reduced overall network resource consumption.

Phase noise tolerant carrier recovery scheme for 28 Gbaud circular 16QAM
- 2015
-
Ingår i: European Conference on Optical Communication, ECOC. - : Institute of Electrical and Electronics Engineers (IEEE). - 9788460817413
-
Konferensbidrag (refereegranskat)abstract
- We propose a novel carrier phase recovery scheme for circular 16QAM coherent transmission systems. Experimental results show low penalties (<1.4 dB) even for linewidths where square 16QAM exhibits irretrievable (above the FEC limit) error floor.
