Anritsu Corporation introduces the 400G multi-speed module (QSFP-DD) MU104014B, which supports the new OpenZR+ interface standard, as the Network Master Pro MT1040A module. OpenZR+ allows you to create low-cost interconnections for data centers (DCI) and metro networks.
This measurement solution supports tests for the transition from expensive networks using existing WDM systems[*1] to low-cost networks using OpenZR+ transceivers. Thanks to this solution, MT1040A helps to reduce the cost of building and expanding the network. With excellent heat dissipation and cooling characteristics, the new measuring module is able to prevent communication failures caused by the release of heat by OpenZR+ transceivers. This allows you to measure network performance more accurately.
Background of the development
Metro's data centers and networks are growing rapidly due to the proliferation of generative artificial intelligence and cloud services, as well as advances in digital transformation (DX) to meet social needs. In particular, restrictions on available space, power supply and air conditioning can cause problems when increasing the capacity of existing medium-scale data centers, so increasing the number of distributed medium-scale data centers may be more efficient than building new hyper-sized data centers, which increases the demand for DCI between more medium-scale data centers data. data processing centers.
WDM circuits supplied by network operators are widely used for DCI, but are expensive. To solve this problem, the 400ZR standard was established[*2], which allows you to create low-cost networks. However, the transmission range of 400ZR is small, and the data transfer rate is only 400G. The OpenZR+ standard was created to support a longer transmission distance and data transfer speeds in the range from 100G to 400G.
OpenZR+ transceivers are inexpensive compared to existing WDM systems. OpenZR+ supports various network configurations and is suitable for building DCI. However, on the other hand, because OpenZR+ is capable of transmitting data over long distances, some OpenZR+ transceivers consume almost 1.5 times more energy than existing 400ZR transceivers and generate more heat. Therefore, in order to accurately measure the OpenZR+ transceiver without malfunction, the measuring module must have a means of measuring the heat dissipation of the transceiver to suppress the heat generated by the transceiver. This measurement solution meets this need.
