Tencent Transmits Single-Wavelength 600Gbit/s Signals Over Its OPC-4 Open Line System

Tencent has successfully transmitted single-wavelength 600Gbit/s signals over its OPC-4 open line system (OLS) using the ADVA FSP 3000 CloudConnect TeraFlex solution. This trial would be a first for the Chinese market and a milestone for metro data center interconnect (DCI) networks.

The trial leveraged ADVA’s FSP 3000 TeraFlex hyperscale DCI technology, which features software-defined optics with “plug-and-play” simplicity. By transporting 600Gbit/s per wavelength over an open 100km OLS, Tencent is highlighting the value of disaggregated solutions to “cost-effectively” meet the growing bandwidth needs of metro data center interconnect infrastructure.

“What this trial proves is that 600Gbit/s services are ready to go,” said Fangchao Li, optical network architect, Tencent. “With the ADVA FSP 3000 TeraFlex plugged into our self-developed open line system OPC-4, we have verified multiple rates from 200Gbit/s to 600Gbit/s through various modulation schemes. With the highest density available in the current market, ADVA’s open and modular 600Gbit/s DCI technology has integrated easily and seamlessly into our OPC-4. That simplicity will be invaluable to operators to meet booming data demand and address changing business needs in real time. With this test, we’re highlighting how ultra-high capacity can now be achieved, while also moving away from static, manual operations to an intelligent, programmable optical layer.”

The pioneering trial involved Tencent utilizing the ADVA FSP 3000 TeraFlex for a 600Gbit/s bidirectional end-to-end transmission across its OLS and a 100km fiber link. Developed for hyperscale DCI applications, the ADVA FSP 3000 TeraFlex would be one of the most high-density transport solutions capable of transmitting 3.6Tbit/s of duplex capacity in a single rack unit with 600Gbit/s bandwidth over a single set of optics.

‘Zero Touch Provisioning’

The ADVA FSP 3000 TeraFlex delivers high energy-efficiency and enables software-defined optics, “giving operators the power to maximize bandwidth for specific capacity and distance needs.” The ADVA FSP 3000 TeraFlex would also offer zero touch provisioning straight from the box for a crucial competitive advantage. What’s more, it provides real-time telemetry streaming for total network visibility and big data-enabled control.

“We believe it’s the first time anyone in the industry has successfully transmitted 600Gbit/s per wavelength over a third-party OLS,” said Rocky Weicong Zhou, director, global business development, ADVA. “The combined solution is easy to install, straightforward to configure and simple to maintain, which represents a huge step forward in freeing customers from vendor lock-in and unleashing the open, disaggregated infrastructure needed for the hyperscale era. With this demo, Tencent has made it clear that it’s ready to lead the way to the next generation of DCI networks. It also underlines the importance of disaggregation for enabling operators to optimize each network layer separately. Finally, this trial shows that our DCI technology opens the door to the full benefits of network service automation, enabling service providers to bring applications to market quicker than ever before.”
