Improved Polarization Tracking in the Presence of PDL
- 2022
-
Ingår i: European Conference on Optical Communication, ECOC. - 9781957171159
-
Konferensbidrag (refereegranskat)abstract
- We propose a novel tracking algorithm for optical channels suffering from fast state of polarization (SOP) rotations and polarization-dependent loss (PDL). Unlike gradient descent-based algorithms that require step size adjustment when the channel conditions change, our algorithm performs similarly or better without parameter tuning.

GNPy : Lessons Learned and Future Plans [Invited]
- 2022
-
Ingår i: 2022 European Conference on Optical Communication, ECOC 2022. - : Institute of Electrical and Electronics Engineers Inc.. - 9781957171159
-
Konferensbidrag (refereegranskat)abstract
- We discuss the history, past challenges and future plans of GNPy, an open source project for simulating physical impairments in contemporary DWDM network. The paper describes the unique interaction among network operators, equipment vendors, and standard bodies, as well as challenges in implementing the digital twin of an optical network.

Continuous Fiber Sensing over Field-Deployed Metro Link using Real-Time Coherent Transceiver and DAS
- 2022
-
Ingår i: 2022 European Conference on Optical Communication, ECOC 2022. - 9781957171159
-
Konferensbidrag (refereegranskat)abstract
- We use an FPGA-based real-time coherent transceiver prototype with continuous μs-level state-of-polarization readouts and a commercial DAS system to perform fiber sensing. Link monitoring and active detection of link tampering is demonstrated using both systems, showing how SOP-based sensing complements DAS in metro environments.

Error-Free 108 Gbps On-Off Keying Link for Optical Interconnect Applications
- 2022
-
Ingår i: 2022 European Conference on Optical Communication, ECOC 2022. - : Institute of Electrical and Electronics Engineers Inc.. - 9781957171159
-
Konferensbidrag (refereegranskat)abstract
- We demonstrate an error-free 108 Gbps OOK link using a C-band externally modulated laser with 3.3 dBm of modulated output power and an O-band directly modulated laser with 7.3 dBm of modulated output power. This paves the way forward for high-speed optical interconnects without FEC.

200 Gb/s Unamplified IM/DD Transmission over 20-km SMF with an O-band Low-Chirp Directly Modulated Laser
- 2022
-
Ingår i: 2022 European Conference on Optical Communication, ECOC 2022. - : Institute of Electrical and Electronics Engineers Inc.. - 9781957171159
-
Konferensbidrag (refereegranskat)abstract
- 200 Gb/s IM/DD transmission over 20-km SMF is demonstrated without any optical amplifiers, achieving BER below the 6.25%-overhead HD-FEC limit, enabled by a broadband and high-power DML with low-complexity digital equalizations.

Learning Optimal PAM Levels for VCSEL-based Optical Interconnects
- 2022
-
Ingår i: 2022 European Conference on Optical Communication, ECOC 2022. - 9781957171159
-
Konferensbidrag (refereegranskat)abstract
- An auto-encoder that optimizes a VCSEL-based fiber-optic system end-to-end and provides a 1.5dB sensitivity gain at higher temperatures is trained, utilizing a neural network that models the response of a VCSEL for a range of operating temperatures.

Nonlinear Fiber Transmission of Compressed Shaping Signals
- 2022
-
Ingår i: 2022 European Conference on Optical Communication, ECOC 2022. - 9781957171159 ; , s. 1-4
-
Konferensbidrag (refereegranskat)abstract
- In nonlinear transmission of compressed shaping signals, the optimum launch power decreases as source entropy decreases, but the maximum Q performance based on soft information increases for either bit-interleaved coded or multilevel coded modulation. The excess degradation is mostly recovered by high-performance multi-channel nonlinearity compensation.
