Steve, I read the article. Very interesting. One takeaway is that the end users are looking for 4x100-gigabit modulators to get to 400. So if that's the case maybe the 50g modulator LWLG revealed is not enough (8x50). Maybe LWLG has to scale up further to 100g. But at that point it would be game over for all others.

“My point to them was that we need a CWDM4 version of 400 gigabits; the LAN-WDM eight-wavelength is a non-starter for all of us,” says Booth. “If you talk to any of the big end users, they will tell you it is a non-starter. They are waiting for the FR4.”

“Everyone wants 400 gigabit - 4x100-gigabit, that is what they are looking for,” says Rajgarhia.

If companies adopt other solutions it is purely a time-to-market consideration. “If they are going for intermediate solutions, as soon as there is 400 gigabits based on 100-gigabit serial, there is no need for them, whether it is 200-gigabit or 8x50-gigabit modules,” says Rajgarhia.

“extending to a 400-gigabit four-wavelength design becomes an engineering matter if the technology platform that is used can scale.” Period.


“When we looked at what is available and how to do an optical interface, there was no good solution that would allow us to meet those timelines, fit the power budget of the QSFP-DD and be at the cost points required for data centre deployment,” says Intel’s Blum. Intel is one of 11 founding companies backing the new MSA.
A disadvantage of the MSA is that it requires eight lasers instead of four, adding to the module’s overall cost. Oops


“Everyone wants 400 gigabit - 4x100-gigabit, that is what they are looking for,” says Rajgarhia. (I think LWLG is quietly working on this)

AGAIN, extending to a 400-gigabit four-wavelength design becomes an engineering matter if the technology platform that is used can scale.


If it is too expensive and too large it is not practical. X

Back in the day while D.C. electric was the darling of the industry with a power plant every few blocks it just was not practical. Eventually A.C. won the day with a power plant at Niagara Falls serving the north east U.S.

While it is possible to reach these speeds you can tell by their comments that the industry understands that new a solution is needed.

Nice Find Stevey,

Xster fun to watch

Steve, thanks for sharing the fascinating article on the race to deliver 400 gigabit optical interfaces for the next generation of data centre switches. It discusses the main players developing the switches such as Finisar, Viavi Solutions, Lumentum, Oclaro, Intel and Arista Networks and the end users such as Microsoft, Alibaba, Amazon, Facebook and Google.

It seems that everyone wants 4X100 gigabit module design and Dr Lebby has put Lightwave Logic in the forefront of discussions with recent presentations on PAM-4 electrical signal that are optically multiplexed onto fibre optics. The next couple of months will be interesting as many of the above top technology companies will want to discuss Lightwave Logics PAM-4 design to answer this multi-Billion dollar data centre business. This is a very exciting time to be an LWLG investor.

Thanks for the article Steve. Did not see it until this morning.
Comments to the article are spot on.
I want to raise attention to the paragraphs below the heading "Challenges and Risk"
Bottom of the second paragraph ("insanely hot and hard" thermal issues).
With out a doubt Lightwave leads ALL electro devices and I know of no other optic devices that can come close to our thermal accomplishments combined with our size. Solving this issue allows Lightwave to design devices capable to be small enough to fit in the existing ports that provide 10g now and will raise that to 100g or MORE without causing heat issues.
Nobody else out there can do this. This is what Lightwave will unveil!!
