With the arrival of the era of big data, the rapid development of Internet services such as VR and cloud computing has further led to the innovation and development of optical fibre and cable. Especially in the transmission rate of optical fibre communication, major optical fibre manufacturers continue to inject funds to increase a scientific research of optical fibre.
Until now, researchers are still proud of the transmission rate of optical fibers, but we know that most of the data only exist in theory, and the actual transmission speed will be affected by various aspects of the loss. Especially in the face of long-distance transmission of large amounts of data, optical fiber can not become a completely trusted transmission mode. However, a recent study may change this situation. Nokia Bell Laboratory, Deutsche Telecom and the University of Munich in Germany recently achieved a data transmission speed of 1 Tbps in a demonstration, which was completed in a simulated real environment.
The secret of high-speed transmission is a new modulation technology, which gives priority to low-amplitude points, which are more insensitive to external influences, than the traditional optical fiber transmission using all constellation points in the network. This technology also allows the transmission rate to be adjusted to adapt to the channel, which can increase the transmission speed by about 30%. Eventually, the team achieved near-light speed.
Of course, this technology is still a long way from being put into civil production. After all, there are still some differences between the actual environment and the experimental environment. But it just happened. To know that 5G cellular data is the future trend, telecom companies need to increase bandwidth to meet the growing demand. Once this technology becomes a reality, it will ensure that network lines do not collapse under high-speed data transmission.
