In 2023, the backbone transmission network for "digital data in the east and data in the west" will enter the 400G era, and the capacity of the trunk optical network will be greatly improved. While the large-scale commercial use of 400G is gradually deepening, the industry is also actively exploring the forward-looking deployment of 800G. 800G long-distance transmission requires continued development of key technologies such as 200GB+ high baud rate devices and C+L+S multi-band transmission based on 400G technology. Conduct research and achieve breakthroughs.

As a communication infrastructure resource, communication pipelines play an important role in today's rapid development of information and communication networks. The scale of operators' communication networks continues to expand, and the development of communication services continues to diversify. In particular, the growing demand for optical cable resources for new services represented by 5G has gradually revealed the shortage of existing network resources, which is reflected in the communication pipelines as pipe holes. There is a shortage of resources, so how to deploy new optical cables?
