Abstract

Space-division multiplexed (SDM) transmission technique using uncoupled multi-core fibers (MCF) is considered a promising candidate for next-generation ultra-high-speed optical transport networks (OTN) due to its huge capacity potential and compatibility with existing OTN transceivers. In this paper, we demonstrate the first real-time 256 Tb/s and 448 Tb/s field trial over deployed 4-core and 7-core MCF cable using commercial 130-Gbaud probability constellation shaping 16-array quadrature amplitude modulation (PCS-16QAM) 800 Gb/s OTN transceivers with 80 wavelength channels. The 4-core and 7-core SDM transmission systems still reserve more than 4.6-dB and 3.7-dB OSNR margins respectively after 2 × 70.76-km transmission thanks to the high-baud-rate coherent modules and the low-crosstalk MCF cable. The 4-core and 7-core fibers inside the fiber cable are both utilize standard 245-μm coating, and the cabling processing has little effect on the characteristics of MCFs. This field trial demonstrates the capacity potential and implementation feasibility of uncoupled MCF in next-generation ultra-high-speed coherent optical transmission networks.

首次使用商用130-Gbaud PCS-16QAM 800 Gb/s OTN收发器在部署的多芯光缆上进行实时超高速现场试验

利用非耦合多芯光纤（MCF）的空分复用（SDM）传输技术由于其巨大的容量潜力和与现有OTN收发器的兼容性，被认为是下一代超高速光传输网络（OTN）的一个有前途的候选技术。在本文中，我们演示了第一次实时256tb /s和448tb /s现场试验，在部署的4核和7核MCF电缆上，使用商用130-Gbaud概率星座整形16阵列正交调幅（PCS-16QAM） 800 Gb/s OTN收发器，具有80个波长通道。由于采用了高波特率相干模块和低串扰MCF电缆，4芯和7芯SDM传输系统在传输2 × 70.76 km后仍能分别保留超过4.6 db和3.7 db的OSNR余量。光纤电缆内部的4芯和7芯光纤均采用标准245 μm涂层，布放工艺对mcf特性影响不大。现场试验验证了非耦合MCF在下一代超高速相干光传输网络中的容量潜力和实现可行性。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
