PacketLight Networks Japan’s 400G DWDM Network With NEC
Ethernet Networks
PacketLight Networks spearheads Japan's quantum-safe communications across fast DWDM networks.
A renowned DWDM and OTN equipment supplier, PacketLight Networks, demonstrated Quantum Key Distribution (QKD) across a 400G DWDM network, changing digital security. This historic feat was made possible by partnering with NEC Corporation, a pioneer in network and IT technology integration, at NEC's cutting-edge Japanese facilities. This milestone shows PacketLight's crucial role in merging modern methods with high-capacity optical networks to secure global data delivery.
The demonstration showed how NEC's cutting-edge QKD technology and PacketLight's PL-4000M 600G Muxponder worked well together. Collaboration produced a powerful, high-performing, quantum-safe network infrastructure. The PL-4000M, a crucial feature of PacketLight, manages huge volumes of data traffic, making 400G data flow across the DWDM system possible.
The QKD channel was transmitted using a dedicated fibre optic link, which was novel. Most importantly, the main data link fibre carried 400G data traffic alongside this unique QKD fibre.
This clever dual-fibre setup protects critical quantum communications, among other benefits. Since quantum signals are vulnerable to noise and interference, their integrity is essential for cryptographic key exchange. The QKD channel is isolated on a dedicated fibre to ensure quantum signal stability and integrity. This method keeps 400G data traffic running efficiently across the current DWDM infrastructure. Businesses can improve communication security without compromising high-bandwidth data transfer speed.
With our dual-fiber configuration, introducing quantum security to operational network environments is economical and scalable. This paradigm advances QKD's main goal, safe key exchange, in real-world applications. This example shows how to improve communication security without costly or complicated network architecture redesigns. By keeping quantum-secure communications affordable and easy to use, this strategy encourages their adoption in many businesses that rely on safe and rapid data transport.
In the rigorous demonstration, PacketLight and NEC experts meticulously validated system compatibility and network performance. Results proved the integrated solution's efficacy and robustness. Specifically, the encrypted data channel maintained low latency and 100% throughput. Independent verification of these critical performance parameters using a 100GbE tester proved the solution's reliability and applicability. This validates that quantum technologies may be deployed alongside current infrastructures without affecting performance or operational networks, especially when paired with PacketLight's DWDM/OTN devices.
Koby Reshef, PacketLight's CEO, was pleased to join this vital partnership. PacketLight's DWDM/OTN devices and NEC's QKD technology provide safe data transmission', he claimed. PacketLight's Mr. Reshef said, "We take pride in our involvement in this cooperation and eagerly anticipate the market's response to the new opportunities it presents." He showed PacketLight's forward-thinking approach and commitment to meeting the expanding demand for cutting-edge cybersecurity solutions in a globalised environment.
Yoichiro Ito, NEC's Director of Innovation Product Solutions Group, Defence Network Department, expressed his satisfaction with the joint demonstration's success. Mr. Ito noted NEC's lengthy research facility in Japan, which has advanced QKD for over two decades, and praised the collaboration.
He added this demonstration demonstrated our QKD system's interoperability with PacketLight's equipment, proving its usefulness in various usage scenarios. NEC confirms PacketLight's efficiency and versatility in enabling cutting-edge quantum security applications. He concluded by reiterating NEC's commitment to working with PacketLight to advance quantum security.
PacketLight and NEC's alliance proves quantum security's technological viability on high-speed networks and sets a baseline for protecting future communication infrastructures from advanced cyberthreats.
Quantum computing can crack many encryption methods, therefore this includes addressing its hazards. A viable and economical way to future-proof data security for corporations, governments, and suppliers of important infrastructure is to add quantum key distribution to present DWDM networks without costly redesigns.
As every industry digitises, unbreakable communication lines will become more important. PacketLight's technology helped this successful demonstration in Japan, which has a big impact on cybersecurity worldwide. It will strengthen global digital communications and usher in a new era of secure data transmission.
