I'm pleased to share our paper entitled "C+L-Band System Design Enabling Spectrally Efficient 800G Long-Haul Terrestrial Transmission" has been accepted for publication in the Journal of Lightwave Technology and is now available on Early Access! ?? ? https://lnkd.in/e_d2mkcV ? In this work we examine how to maintain consistent spectral performance across a wideband long haul transmission system, composed of hybrid Raman-EDFA C+L amplifiers and high performance Corning TXF fiber. By modeling and optimising the line system using a digital-twin, we were able to support a total capacity of 72 Tb/s over 1504 km with an average spectral efficiency exceeding 7 b/s/Hz using ICE6 transponders. This represents the highest real-time capacity-distance product of any multi-band system to date. ? Thanks to my co-authors Ivan Fernandez de Jauregui, Ph.D, Nurmemet Abdukerim Aytoldi, Ravikiran Kakarla, Francisco Javier V., Lidia Galdino and Sergejs Makovejs and Jonathan Buset, Ph.D. for their invaluable expertise and support. I look forward to more great collaborations between Infinera (Nokia?!) and Corning Incorporated in the future!?

New Achievement!! The paper titled "Demonstration of Broadband Data Link over off-the-shelf Solar Module with White LED" by Rahul, Anand Srivastava, Vivek Ashok Bohara, D. Solanki, and Abhijit Mitra has been accepted in the IEEE/OPTICA PUBLISHING GROUP Journal of Lightwave Technology. Abstract:?This paper experimentally demonstrates high-speed data transmission using an off-the-shelf polycrystalline solar module while using a commercially available white light-emitting diode (LED) as an optical source. Solar panels are one of the major contributors to renewable energy sources, and their capability to provide high-speed data transmission makes them a viable contender for self-powered communication receivers. A bigger receiver area of the solar panel mitigates losses due to pointing errors, angle of arrival fluctuations, and misalignment in a communication link. This paper presents a bandwidth enhancement circuit (BEC) that enhances the 3-dB bandwidth of an off-the-shelf solar module-based receiver for facilitating visible light communication (VLC). The performance is compared with the other solar receiver designs, such as resistive load and passive equalization. We show that a data rate of 18.85 Mbps is achieved with the 16 quadrature amplitude modulation (QAM) orthogonal frequency division multiplexing (OFDM) over a VLC link of 330 cm. Optical lenses based on the total internal reflection (TIR) phenomenon are mounted over white LEDs to increase beam coherence, thereby increasing the transmission distance. We congratulate the authors for this great achievement.

I’m excited to share that our work on deployed fibre transmission using more than 100 nm of optical bandwidth has been accepted for publication in the Journal of Lightwave Technology! This study explores the feasibility of incorporating the S-band to achieve a more than 50% increase in throughput for deployed fibre transmission, in both short-reach and long-haul (>1000 km) scenarios. Be among the first to explore our findings—early access is available here: https://lnkd.in/ePTSJC_z. This work was in collaboration with NICT and Coherent Corp.. Special thanks to Dr. Wakayama from KDDI Corporation for his support.
