Moving to 400G (400 Gigabit Ethernet) technology can bring a multitude of benefits for networks that need to effectively handle a steep increase in traffic demand, stemming primarily from video, mobile, and cloud computing services. Some of the essential benefits are:
Increased capacity and speed: 400G offers 4 times the bandwidth of 100G, greatly bolstering network capacity and throughput for data-intensive services and applications.
Efficiency and scalability: 400G is inherently more efficient because it can carry more information per transmission. This efficiency also provides future-proofing for providers as traffic demands grow.
Cost-effectiveness: Enable 2-4X lower cost and power/bit, reducing capex and opex. Even though the upfront capital expenditure might be higher, the total cost of operation can be reduced in the long run because you can move more data with fewer devices, leading to reductions in space, power, and cooling requirements.
Improved network performance: With greater speed and capacity, 400G technology reduces latency, providing an overall improvement in network performance. This is crucial for time-sensitive applications and can significantly enhance the user experience.
Support for higher bandwidth applications: Increase switching bandwidth by a factor of 4. Migrating from 100G to 400G systems increases the bandwidth per RU from 3.2-3.6T to 12.8-14.4T / RU. The rise in high-bandwidth applications, like Ultra High Definition (UHD) video streaming, cloud services, online gaming, and virtual reality (VR), require strong, stable, and fast network connections. 400G technology can provide the necessary support for these bandwidth-intensive applications.
Enables machine-to-machine communication: 400G technology is a powerful tool for enabling machine-to-machine communications, central to the Internet of Things (IoT), artificial intelligence, and other emerging technologies.
Supports 5G networks: The higher speed and capacity of 400G technology are ideal for meeting the demanding requirements of 5G networks, helping them to achieve their full potential.
Data Center Interconnect (DCI): For enterprises operating multiple data centers at multiple sites, 400G supports efficient and powerful data center interconnection, enhancing data transfer and communication.
Sustainability: 400G is more energy-efficient than its predecessors by providing more data transmission per power unit. This is a significant advantage considering the increasing global focus on sustainability and green technology.
Enable higher-density 100G ports using optical or copper breakouts. A 32 port 1RU 400G system enables 128 100GE ports / RU. This allows a single Top of Rack (TOR) leaf switch to connect to multiple racks of servers or Network Interface Cards (NICs).
Reduce the number of optical fiber links, connectors, and patch panels by a factor of 4 when compared to 100G platforms for the same aggregate bandwidth.
In conclusion, 400G technology presents a compelling solution for networks dealing with high traffic flows due to digital transformation trends. It builds the foundation for supporting the growing demand for data from businesses and consumers alike, making it an important tool in the era of 5G, and IoT.
