Upgraded Sampling Oscilloscope MP2110A Clock Recovery Function

Anritsu Corporation has launched its new 25G Clock Recovery Range Expansion Option (MP2110A-059) to upgrade the BERTWave MP2110A sampling oscilloscope clock recovery rate required for testing optical signals. Reduces 64GFC (64G Fibre Channel) PAM4 Optical Module Production-Line Costs.

This option facilitates optical-waveform tests of Fibre Channel compliant 64GFC PAM4 optical modules in a clock-signal-free test environment. The upgrade helps assure the quality of 64GFC PAM4 optical modules while simplifying the production line configuration to cut costs.

Development Background
The number of datacenters is growing worldwide to cope with the huge increases in data traffic volumes caused by the 5G rollout and spread of IoT. The many optical connections between intra-data-center network racks, servers, and storage use different optical transmission speeds and interfaces. Since standardization of the 64GFC interface for use by datacenters has been completed, this interface is expected to enter widespread use from 2022. Anritsu’s released MP2110A-059 function upgrade option supports tests of these 64GFC optical modules to meet demand from this growing market.

Moreover, introduction of 400GbE is driving a switch from NRZ to PAM4 modulation, while Fibre Channel is also similarly changing from 64GFC to PAM4. This technology paradigm shift requires higher-accuracy testing because PAM4 modulation has smaller performance margins than NRZ.

Higher-accuracy testing requires clock recovery to extract the clock signal from the measured signal and Anritsu has developed this 64GFC clock recovery function based on its earlier support for 400GbE technology to help support more accurate measurement.

Product Outline
The all-in-one MP2110A BERTWave combines a bit-error-rate tester (BERT) with a sampling oscilloscope for evaluating communications waveforms. The multi-channel sampling oscilloscope is ideal for configuring a versatile, cost-effective, customized test environment to improve production-line throughput using parallel all-at-once measurement with four high-speed channels.
