Professional provider of high-end integrated DWDM solutions for big data transmission

In modern society, mobile phones have become an indispensable communication tool in our daily lives. When we dial a phone number and talk to relatives and friends far away, there is actually a series of complex and sophisticated working principles hidden behind it. Do you know how signals are transmitted when you are talking to relatives and friends? The first step in a mobile phone call is the transmission of the signal. When the call is connected, the mobile phone will continue to send signals to the nearby base station, telling the base station to transmit the signal. The base station will transmit the signal to the nearest data center, and then pass the signal through the aggregation layer, backbone network, and core network. After being transmitted, it passes through the core network, backbone network, aggregation layer, and base station, and then the signal is delivered to the target mobile phone. As shown in the figure below, in the process of signal transmission, DWDM optical t...

In today's society, the application of hyper-internet is very extensive, mainly in the following aspects:Super Computing Dedicated Network , Internet Service Operator, Data center interconnection , Government and Enterprise Dedicated Network,Internet. Super Computing Dedicated Network With the advent of the era of super computing power and AI, computing power, as a productive force, is playing an increasingly important role. To achieve a high-quality computing network, it is necessary to build a deterministic basic network with large bandwidth, low latency, and deployable capabilities. Internet Service Operator Cloud services and Internet customer demands have promoted the large-scale development of data center interconnection (DCI). Long-distance interconnection, intra-city interconnection, and interconnection around hotspot areas. Supercomputing power has driven the explosive growth of inter-DC traffic. Operators have laid out plans to build DC interconnection and high-speed Inte...

We know that since the 1990s, WDM wavelength division multiplexing technology has been used for hundreds or even thousands of kilometers of long-distance optical fiber links. For most countries, fiber optic infrastructure is their most expensive asset, while the cost of transceiver components is relatively low. However, with the explosive growth of data transmission rates in networks such as 5G, WDM technology is also becoming increasingly important in short-distance links, which are deployed in much greater volumes and therefore have an impact on the cost of transceiver components. and size are also more sensitive. Currently, these networks still rely on thousands of single-mode optical fibers for parallel transmission through spatial division multiplexing channels, and the data rate of each channel is relatively low, only a few hundred Gbit/s (800G) at most. T-level is possible There are few applications.   But in the foreseeable future, the concept of ordinary space parallelizat...
