DEMONSTRATING MULTISPEED INTEROPERABILITY
June 18, 2020
From 10GbE to 400GbEDave Estes, Spirent
Validating Multi-Vendor Interoperability
www.ethernetalliance.org 9
§ Who? 17 Ethernet Alliance members
§ Why?- Implement the most complex demonstration possible
proving Ethernet’s robust connectivity/interoperability and compliance to Ethernet specifications demanded by emerging markets and applications
- Highlighting the importance of testing early in an innovation’s development cycle to ensure interoperability and accelerate time to market
§ How?- Components (switches, routers, cables, optics, interconnects) ranged across various form factors
and speeds interconnected with all compatible components and test and measurement solutions
www.ethernetalliance.org 10
The Equipment List
- It all starts with a list…
- Months of careful collaboration with multiple participants on what equipment to showcase
- Identifying demonstration details based on available vendor equipment
- Mapping switches/routers including port counts & capabilities
- Aligning cables/optics/fibers to compatible components
- Dreaming big…

The White Board- Visualizing “minimum” number of connections to deliver
maximum impact
- Incorporating traffic routes and verifying interoperability (i.e. connections are operating error-free)
- Optimizing available ports and interconnects
- Diversifying showcase to highlight latest technologies and industry innovations

The Hot Stage
- 17 participating vendors, 3 days of testing, all equipment onsite to build a fully functioning network
- Testing every connection to ensure interoperability
- Optimizing showcase with additional connections
- Collaborating to resolve issues experienced
- Testing integration with 200G/400G switch network
- Displaying all connections in a single diagram

ETHERNET CHALLENGES ON 400GE INTEROPS
June 18, 2020
Anabel Alarcon - EXFO
www.ethernetalliance.org 16
Tsunami Alert.. Since 400GE appeared on the market a complete ecosystem was born, including the following elements:
§ Form Factors (OSFP, QSFP-DD, CFP8)
§ Modulations (PAM4, NRZ)
§ And more flexible ways to transport ethernet traffic(FlexE)
Form Factors Modulation Rates Flex E
17www.ethernetalliance.org
The different sorts of form factors and ratesout there have generated an extensivevariety of transceivers and cables.
As a test an measurement company wevalue a lot the opportunity to interop withnew manufacturers and test newtechnologies on plug fests and interops.
§ That really gives us the opportunity to quicklyadapt to market trends.
§ Also allowing us to create new tools. Exampleread registers, etc.
Wide variety of interfaces
New challenges …
www.ethernetalliance.org 18
400G/200G transceivers and cables include a new type modulation PAM4(Pulse Amplitude Modulation 4) that has different characteristics and new challenges.
Key challenges
§ Three eyes per lane§ Different electrical
characteristics
New challenges new tools
www.ethernetalliance.org 19
PAM4 pluggables introduce a higher level of complexity, new flexible tools to test and validate them are required

Different players
Another element inside ethernet networks is theincreasing number of switch fabrics, on data centers,clouds, core, edge, etc.
Key lessons learned when testing these fabrics atinterops:
ü Clean your fibers
ü Generate L2/L3/L4 traffic
ü BERT with different frame sizes (EMIX)
ü Smart loopback (very useful during interop’s)
FlexE Ethernet
www.ethernetalliance.org 21
Another member of the 400G ecosystem is Flexible Ethernet
§ The objective of this technology is to transport several mix clients with different bandwidth (5G, 25G up to 400G) using different high speed interfaces.
§ All the management is done at Layer 2, and its even possible to assign a specific mac address to each client.
400G/200G Coherent Optics
800G debut
400G/200G Deployed massively
Going forward ….

Summary
www.ethernetalliance.org 30
Cabling, Connectors, and Optical Modules are interoperable with leading switches, servers, and test equipment - even at 400G.
Ethernet Standards have created an eco-system where customers can choose components from multiple vendors over multiple data rates and have them all work together.
