Challenges in Data Center Interconnect (DCI) Installation Configuration of Data Center network through Metro Network

The scale of data centers is expanding to provide optimal performance to meet increasing demands. Because of these demands and other factors such as real estate constraints, power consumption, and latency issues, data centers are shifting to a more distributed model. Therefore, the number of data center interconnects is increasing but the Wavelength Division Multiplexing (WDM) system will require a high cost to achieve good performance.

Market Trends in Data Center

400GBASE-ZR (400ZR) technology is expected to reduce the cost for DC operators because 400ZR does not need the installation of WDM systems including transponders. However, DC operators are required to guarantee the performance by themselves as the maintenance of several WDM components such as 400ZR transceiver becomes their responsibility.

400GBASE-ZR (400ZR) technology is expected to reduce the cost by DC operators, while it is required to guarantee the performance by themselves.

Challenges in 400ZR Deployment

DCI Deployment Process

Structure of Data Center Interconnect on the Existing WDM System Structure of Data Center Interconnect on the 400ZR. There are challenges that DC operator would face when installing 400ZR.

Challenge 1: Need to guarantee the performance on 400ZR by DC operators themselves

The deployment of 400ZR network contributes to a reduction in costs, while DC operators need to guarantee the signal quality of their network equipment. For example, before introducing 400ZR transceivers which can switch an optical wavelength, DC operators should confirm that the optical wavelength keeps within the specific channel bandwidth. And then, the Ethernet frame test is required.

Want to complete the installation procedure easily and efficiently, but transport performance measurement is necessary.

Challenge 2: Require easy and efficient installation procedure

DC operators need to establish a procedure that enables their engineers to easily operate and test transport performances in 400ZR optical networks. This is because DC operators themselves must construct their network and guarantee the quality of the communications in their networks.

Solution 1: MT1040A and MS9740B support for confirming the performance at transceivers, communication networks, client servers

MT1040A directly connects to a 400ZR transceiver to provide a quality testing environment for 400ZR DCI network. In addition to the standard Ethernet frame testing to confirm the bit error rate and the number of TRx frame, the MT1040A can import the monitored values of the quality of communications and display them on the screen. And then, an optical spectrum analyzer MS9740B measures and confirms that the output power, wavelength, and signal bandwidth meet the required network specifications.

Solution 2: Efficient automated on-site testing by MT1040A

The automatic test scenario for 400ZR on the MT1040A makes it easy to perform the test described in Solution 1 above.

Since the automated testing using a scenario displays on-screen operation guidance, even operators with only minimum training can test easily without operation errors.
