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.
