人民日报客户端2月12日消息，我国光通信技术再次取得突破性进展。记者日前从中国信息通信科技集团获悉，科研人员在国内首次实现1.06Pbit/s超大容量波分复用及空分复用的光传输系统实验，可以实现一根光纤上近300亿人同时通话，标志着我国在“超大容量、超长距离、超高速率”光通信系统研究领域迈向了新的台阶。

据介绍，本次实验采用的传输介质是一种单模19芯的特种光纤，为我国自主研制，相比此前单模7芯光纤，传输能力大为增强，传输容量是目前商用单模光纤传输系统最大容量的10倍，可以在1秒之内传输约130块1TB硬盘所存储的数据。相比2017年实现的560Tb/s光传输系统实验，容量几乎倍增。在材料上，本次实验采用的是我国自主研发的硅基材料芯片，而不是传统的三五族材料芯片。
该系统设备在C+L波段内产生了375个光载波，基于硅光相干收发芯片实现了25GHz通道内的178.18Gbit/s DFTs-PDM-16QAM信号光收发，在单模19芯光纤内完成了光传输验证，谱效率达到了113bit/s/Hz，传输总容量达到1.06Pbit/s，首次实现了从“Tb/s级”到“Pb/s级”的突破。
据光纤通信技术和网络国家重点实验室贺志学博士介绍，随着数据通信呈现爆炸式增长，对现有的基础网络产生巨大的压力。三超光传输将更好地缓解数据传输压力，为迎接5G时代的到来做足准备。

People's Daily client February 12 news, China's optical communications technology once again made breakthrough progress. The reporter recently learned from China Information and Communication Technology Group that the researchers realized the first 1.06 Pbit/s ultra-large capacity wavelength division multiplexing and space division multiplexing optical transmission system experiments in China, which can realize nearly 30 billion simultaneous calls on one fiber. It marks that China has taken a new step in the research field of "ultra-large capacity, ultra-long-distance, ultra-high-rate" optical communication systems.

According to reports, the transmission medium used in this experiment is a single-mode 19-core special fiber, which is independently developed by China. Compared with the previous single-mode 7-core fiber, the transmission capacity is greatly enhanced, and the transmission capacity is currently commercial single-mode fiber transmission. 10 times the maximum capacity of the system, it can transfer data stored in about 130 1TB hard disks in 1 second. Compared to the 560Tb/s optical transmission system experiment implemented in 2017, the capacity is almost doubled. In terms of materials, this experiment uses silicon-based material chips independently developed by China, rather than traditional three-five material chips.

The system equipment generates 375 optical carriers in the C+L band, and realizes 178.18 Gbit/s DFTs-PDM-16QAM signal transmission and reception in the 25 GHz channel based on the silicon optical coherent transceiver chip, which is completed in the single mode 19-core fiber. Optical transmission verification, the spectral efficiency reached 113bit/s/Hz, and the total transmission capacity reached 1.06Pbit/s. For the first time, the breakthrough from "Tb/s level" to "Pb/s level" was realized.

According to Dr. He Zhixue, National Key Laboratory of Optical Fiber Communication Technology and Network, with the explosive growth of data communication, tremendous pressure on the existing infrastructure network. The three super-light transmission will better alleviate the pressure of data transmission and prepare for the arrival of the 5G era.

Record breaking fiber transmission speed reported

NICT Network System Research Institute and Fujikura Ltd. (Fujikura, President: Masahiko Ito) developed a 3-mode optical fiber, capable of wide-band wavelength multiplexing transmission with standard outer diameter (0.125 mm) that can be cabled with existing equipment. The researchers have successfully demonstrated a transmission experiment over 1045 km with a data-rate of 159 Tb/s. Multimode fibers have different propagation delays between optical signals in different modes that makes it difficult to simultaneously satisfy large data-rates and long distance transmission. This achievement shows that such limitations may be overcome.

Converting the results to the product of data-rate and distance, which is a general indicator of transmission capability, results in 166 Pb/s×km. This is the world record in a standard outer diameter few-mode optical fiber and the largest data-rate over 1000 km for any kind of standard-diameter fiber. In order to achieve the transmission capacity of 159 Tb/s, mode multiplexing is used in combination with 16-QAM (quadrature-amplitude modulation), which is a practical high-density multilevel modulation optical signal, for all 348 wavelengths and MIMO (multiple-input and multiple-output) enables unscrambling of mixed modal signals even after transmission over more than 1000 km. This shows that standard outer diameter multimode fibers can be used for communication of high capacity optical backbone transmission systems.

The results of this demonstration were selected for presentation as a post-deadline paper at the 41st Optical Fiber Communication Conference and Exhibition (OFC2018).

In order to cope with ever-increasing communication traffic, research on large-scale optical transmission using new types of optical fiber exceeding the limit of conventional optical fiber and its application is actively conducted all over the world. The main new types of optical fibers studied are multicore fibers in which multiple passages (cores) are arranged in an optical fiber and multimode fibers that support multiple propagation modes in a single core with a larger core diameter. Up to now, successful transmission experiments of large capacity and long distance have been reported for multicore fiber, but it was considered that transmission which satisfied both large capacity and long distance simultaneously was difficult in multimode fiber.

In this work, NICT constructed a transmission system using an optical fiber developed by Fujikura and successfully transmitted over 1045 km with a data-rate of 159 Tb/s (Fig. 1). Converting the results to the product of transmission data-rate and distance, which is a general indicator of transmission capability, is 166 Pb/s×km. This is about twice the world record so far in the few-mode fibers.



The transmission system consists of the following element technologies.

• 3-mode optical fiber with standard outer diameter 0.125 mm
• 348 wavelength optical comb light source
• 16-QAM multi-level modulation technology equivalent to 4 bits / single polarization symbol
• Separation technology of multimode optical signals with different propagation speeds in fiber (MIMO processing)

The researchers succeeded in transmitting over 1045 km using a standard 3-mode optical fiber. When laying of standard outer diameter optical fibers takes place, the existing equipment can be used and the practical use at an early stage is promising. Also, ultimate large-capacity transmission will become possible in the future if combined with multicore technology, which is researched by NICT in cooperation with industry, university and government in Japan.

The researchers will continue to research and develop future optical communication infrastructure technologies which can smoothly accommodate traffic such as big data and 5G network services.

KNN!

My HDD is 8TB capacity took me hours to backup copy.

This fiber will transmit all it's contents within less than 1/10 of a second!



Actually about 13 of this HDD contents can fly through this fiber within 1 second!
