“…There have been substantial efforts to implement the MBT systems to the optical transmission network. In the lab test validation, recently, using discrete amplifiers covering a 97 nm wavelength range, a 63.2 Tbit/s system transmitting over 440 km has been demonstrated, which shows a feasible implementation of the MBT system in the metropolitan networks [9]. In [10], a 112.8 Tbit/s real-time transmission over 101 km G.654.E fiber has been demonstrated, which is amplified by thulium-doped fiber amplifiers (TDFA) for S band and erbium-doped fiber amplifiers (EDFA) for C+L band with the help of hybrid forward-and backward-pumped distributed Raman amplifiers.…”

Power unevenness, mainly induced by stimulated Raman scattering, has been a major problem in multi-band transmission systems, especially in the upcoming field-deployed 400 Gbit/s widened C band plus L band system for backbone long-haul and ultra-long-haul scenarios. To reduce the impact of power unevenness, we propose an automatic power optimization (APO) algorithm to guarantee reliable transmission for all channels, especially the channels at short wavelengths. The simulation results show that the power unevenness of output power after 5-span transmission in the C band is up to 11 dB before APO, while after APO is applied, it is greatly improved to less than 1.6 dB. To further investigate the performance of the APO scheme, we conduct a real-time 44 Tbit/s C+L transmission system over 1900 km G.654.E fiber utilizing 400 Gbit/s transponders. The experimental results show that the power unevenness has been effectively compensated from 12 dB to 4 dB in the entire 11 THz range, making the received optical signal-to-noise ratio relatively flat (3.4 dB). Moreover, the capacity and distance product of this system is 83.6 Pbit/s·km (44 Tbit/s × 1900 km), and to the best of our knowledge, this is a record capacity and distance product in the real-time single-mode fiber transmission system.

In the past decade, China has made great investments in studying photonics and photocommunication with larger communication capacity, better performance, and lower cost. After years of heavy investment, great progress has been made in academic research, manufacturing capabilities, and optical network scale. The number of papers written and published by researchers in China in the world’s top optical fiber communication conferences has increased year by year, accounting for about 10% of the total number of papers. These high-level articles show that scientists in China have made great strides in photonics research in devices, systems, and networks. On the other hand, photonics industrialization in China is getting more competitive with its large market scale and strong production capacity.

In this work, polarization modulator utilizing MXene material, namely Nb2C is demonstrated. S band signal is injected into Nb2C thin film and is modulated by 1400 nm laser diode. A total of 39.81° of polarization rotation is attained when the pump power is increased to 223 mW. The rotation of light is due to thermo-optic effect. The efficiency of polarization modulator is calculated at 0.1974°/mW.
