Tencent announced today that it has completed an 80-km fiber transmission of multiple 200G 8QAM signals using Acacia's modules on third-party switches.

The signals were sent over Tencent's OPC-4 open line system (OLS) using Acacia Communications’ CFP2-DCO modules.

In order to simulate higher fiber loss in its metro networks, Tencent added 10dB optical attenuators to the tested link, and was still able to achieve error-free operation in all the ports. OPC-4, which was developed by Tencent, meets its software-defined networking (SDN) requirements for a disaggregated transport network, and is fully integrated into the company’s network controller.

Tencent said that the lab demonstration validates the deployment readiness of its IP over dense wavelength division multiplexing (DWDM) solution using OPC-4 in its metro data center interconnect (DCI) networks.

The demonstration used Acacia’s CFP2-DCO modules with 50GHz channel spacing and 200G 8QAM modulation, which also showed the ability to support transmission of up to 19.2T on a single fiber using Tencent’s 96-channel OPC-4 and Acacia’s CFP2-DCO modules.

The demonstration highlighted the value of IP over DWDM and disaggregated solutions to cost-effectively meet the growing bandwidth needs of Tencent’s metro DCI infrastructure, the companies said.

"With Acacia’s 200G CFP2-DCO, our switch platform can support eight ports, for up to 1.6T per line card and our OPC-4 can support transmission of up to 19.2T over a single fiber for metro DCI applications," said Tencent's Jengyi Geng, senior network architect in a statement. "In addition, the CFP2-DCO form factor provides us with a pay-as-you-grow deployment model."
