Anritsu Presents Network Master Pro for Data Centers

WDM circuits provided by network operators are used widely for DCI but are expensive.

Anritsu Corporation has released its Network Master Pro 1040A now supporting tests of 400GBASE-ZR standard optical modules facilitating low-cost data centers interconnects (DCI).

Anritsu Data CenterIn addition, Anritsu has also developed the optional Ethernet 4x100G N Port BERT and Ethernet 2x200G N Port BERT M1040A software solutions for breakout-type communications quality tests to reduce DCI test workloads.

These upgraded functions supporting tests for transitioning to 400GBASE-ZR circuits as well as the introduction of breakout-type interfaces will help cut data center construction and expansion costs.

Data centers are growing at a rapid pace due to the spread of 5G services, teleworking, and online teaching as well as advances in digital transformation (DX) meeting social needs.

Limits on available space, power-supply capacity, and air-conditioning can cause problems in scaling up the capacity of established medium-scale data centers so increasing the number of distributed medium data centers can be more efficient than building new hyperscale data centers, which is driving demand for DCI between more medium-scale data centers.

WDM circuits provided by network operators are used widely for DCI but are expensive.

Recently, the market trend towards opening and disaggregation of WDM systems is driving demand for 400GBASE-ZR transceivers, which is helping cut circuit costs.

On the other hand, each data center becomes more efficient at the same time.

Although high-speed data center interconnects (DCI) link separate data centers, the many low-speed distribution port connections occupy a large data center space. This space-saving issue is solved by using breakout-type interfaces.

For example, the 400GBASE-XDR4 standard uses only one 400G port on the same panel whereas four 100G ports were previously required, which is four times more space-efficient than running four 100G cables.

Moreover, less power is used because the number of laser elements is reduced from the four required for each of the communications wavelengths used by the four 100G links to one laser used by the 400G link. However, the introduction of these breakout-type interfaces by data centers requires transceiver and equipment acceptance tests.

With these upgraded functions, Anritsu’s MT1040A is the ideal measurement solution for evaluating communications quality when data centers introduce this new DCI technology.
