TOKYO, JAPAN – Ciena (NYSE: CIEN) announced today that Colt Technology Services (Colt) is now able to run high-capacity services across long distances spanning more than 500km using Ciena’s industry-leading coherent technology.

With Ciena’s 6500 Reconfigurable Line System (RLS), Waveserver 5 compact interconnect platform powered by WaveLogic 5 Extreme (WL5e) coherent optics, and Manage, Control and Plan (MCP) domain controller, the upgrade more than doubles Colt’s network capacity.

“We continue to improve our service offerings on the Colt IQ Network, enabling us to better respond to the explosive traffic demands in Japan and drive faster service launches. The Colt IQ Network is designed to provide high-bandwidth, on-demand connectivity, and we continue to deliver on this promise by collaborating with industry pioneer Ciena,” said Masato Hoshino, Representative Director & President, Head of Asia, Colt Technology Services Co., Ltd.

With the Ciena 6500 RLS, Colt can simplify deployment, operation, and troubleshooting with built-in tools like Zero-Touch Provisioning (ZTP), network auto-discovery, and real-time network monitoring and visibility. Network adaptability is also enhanced with automated calibration. Additionally, with RLS’s integrated L-band amplification and ASE noise loading, the upgrade has no impact to existing C-band traffic and does not require any visits or changes to line amplifier sites, enabling stable and uninterrupted service launches.

“Throughout Japan, there is a growing ask to support the connectivity needs required to run cloud-based applications and bandwidth-heavy video content. Designed with programmability, performance, and scalability in mind, Ciena’s 6500 RLS enables Colt to deploy C&L-band optimized equipment with no service interruptions, empowering Colt to bring the digital universe to its customers faster than ever before despite the distance,” said Kazuyasu Takahashi, Vice President and General Manager, Ciena Japan.

This upgrade to the Colt IQ Network follows an earlier milestone, when Colt, in collaboration with Ciena, became the first provider to transport 600G wavelength services in a long-haul live network in Japan.
