Keysight Technologies has launched the first compliance test system for validating 112Gbit/s serial data centre interface to the latest industry standards. 

Data centre operators and hyperscalers are implementing 800 gigabit (800G) as the next generation of data centre connectivity technology, to address bandwidth, virtualization and switching capacity requirements as well as the need for cost-effective power efficient data transportation. Interfaces capable of supporting speeds of at least 100 Gbps and per lane are critical to realizing the benefits of 800G deployments.

Keysight’s 112 Gbit/s conformance test platform enables optical transceiver manufacturers to accurately verify both the transmitter (TX) and receiver (RX) of designs that support connectivity speeds of 100 Gbps or greater. 

 “Keysight’s contributions to industry standards bodies are advancing hyperscale network measurement science and design validation solutions for 100Gbps technology,” said Dr. Joachim Peerlings, vice president of network and data centre solutions at Keysight Technologies. “We leverage insights gained from working with key stakeholders across the ecosystem to create interoperability and physical layer conformance test tools. These tools speed design and development ranging from electrical simulation to early silicon and systems validation.” 

Keysight’s fully automated conformance test system enables developers to perform flexible, precise and repeatable testing across a variety of implementation scenarios, to minimize development schedules. 

A wide range of test cases for validating compliance to the latest specifications defined by both the Institute of Electrical and Electronics Engineers (IEEE) and the Optical Internetworking Forum (OIF) can be used to simplify and accelerate testing of multiple interfaces, including chip-to-chip, chip-to-module, cabled and backplane. 

The conformance system uses the Keysight M8040A 64 GBaud high performance bit error ratio tester (BERT) with a N1060A Digital Communication Analyzer (DCA) for receiver testing and Keysight’s Infiniium UXR-Series real-time oscilloscope for transmitter testing.
