E new fiber "paves" the way for 400G deployment
.

At the same time, with the implementation of the "Broadband China" strategy, the construction of optical network cities has been fully promoted, and more optical fiber and cable products for FTTx deployment have emerged
.
The in-depth coverage of 4G networks and the vigorous development of data centers have also brought new opportunities
to the optical fiber and cable industry.

Driven by the multiple impetus of market and technology, China's optical fiber and cable industry is ushering in a new round of development, and the innovation of optical fiber and cable technology is also laying the foundation
for the accelerated application of ICT technology to all walks of life.

From 40G a few years ago to 100G currently deployed on a large scale, and then to the future 400G, 1T and other higher speed WDM, the continuous improvement of optical transmission network performance is prompting the industry to break through the performance bottleneck of existing optical fibers and develop new optical fiber technologies
suitable for the ultra-100G era.

E fiber released in September this year will pave the way for large-scale deployment of future 400G networks with its large effective area and low/ultra-low loss
.

At present, China Unicom has carried out the pilot verification of 400G live network based on G.

E fiber, evaluated its transmission performance and environmental adaptability, and laid the foundation
for the introduction of G.

E fiber in the backbone high-speed transmission network in the future.

In addition to optical fiber and cable manufacturers, major mainstream system equipment manufacturers are also actively involved in China Unicom's 400G live network pilot verification, technological development needs the support of the entire industry, only all links of the industrial chain join hands to finally achieve technological breakthroughs and bring large-scale applications
.

China Unicom will uphold an open and win-win attitude, share the results of live network verification with the industry, and hope that more manufacturers will participate in it to lay a solid foundation
for the arrival of the 400G era.

Changfei will continue to increase the research and development of G.

E optical fiber, share the latest technologies and products with the industry, and provide strong support
for 400G live network pilot verification and future large-scale deployment.
