Cloud services are becoming increasingly important due to the rapid spread of teleworking and online learning as well as advances in digital transformation (DX). Data centers supporting these cloud services are constantly upgrading communications equipment, optical modules, etc., to offer faster speeds, power efficiency, etc., supporting the best cloud services for customers.
High-Speed Serial Bus
- PCI Express
- Sampling Oscilloscope
- Optical Spectrum Analyzer
- Data Center Interconnects (DCI) I&M
- Automated and Efficient Network I&M Tests
- Optical Fiber Network Verification
Data Centers use a variety of technologies.
Anritsu has measurement solutions for evaluating technologies used by cloud services and data centers including modules still in development such as 400G.
High-Speed Serial Buses
The MP1900A is targeted at receiver testing for next-generation high-speed digital interfaces, such as PCI Express, Thunderbolt, and USB3.0, to improve the efficiency of design tests, device communications verification, and Jitter load margin inspection tests. This section describes some test configurations for actual interfaces as well as measurement methods.
Ultra High –Speed Device and optical module R&D Solution
The MP1900A has built-in PPGs generating wideband multichannel high-quality NRZ/PAM4 signals, a high-input-sensitivity ED, and a Jitter modulation source. This section describes efficient evaluation of optical modules and devices using the built-in noise generation source and 10Tap Emphasis.
The MP1900A supports multichannel high-baud-rate PAM4/NRZ signals with different optional PAM4 combiner units for extended range of testing functions. This section describes the role that the basic test-signal Intrinsic Jitter and high input sensitivity functions play in helping improve design test efficiency.
Optical Module and Device Manufacturing Solution
The BERTWave MP2100B is measuring instruments for optical modules and device production lines. With a built-in BERT and sampling oscilloscope they can simultaneously perform the Eye pattern analysis and bit error rate measurements required for evaluating optical-modules performance. Optical modules manufacturing throughput is increased by the shorter test times resulting from the high-speed measurement. Additionally, the high-sensitivity receiver helps improve line yields because the measurement results reflect DUT characteristics more accurately.
The high resolution and fast sweep speed of the MS9740B both play a key role in more efficient VCSEL, DFB-LD, Silicon Photonics, etc., evaluations. This section describes both aspects from the viewpoint of shorter test times and faster production-line test equipment switchover. Click here for more information about these functions.
The spread of cloud services, SNS (Social Networking Service), and video streaming is increasing the number of businesses using distributed metropolitan data centers (Metro DC) as interconnects. This section describes some solutions using the MT1040A for troubleshooting and installing data center interconnects (DCI).
Inspection at optical communications network installation as well as network maintenance is key factors in offering good services. This section explains solutions for eliminating human errors at on-site network I&M.
- Easy Evaluation of Optical Fiber Status
The fastest possible communication speeds are negatively affected by optical fibers installed inside and outside of data centers by reflections resulting from optical fiber connectors and splices. Anritsu's handheld Optical Loss Test Set makes it easy to measure optical power, while the Optical Fiberscope is useful for visually checking the condition of the optical fiber end faces, and an OTDR provides an easy to grasp icon-based visualization of events, such as connectors and splices along the fiber length.
