Upgrade your network infrastructure with the new 800G QSFP-DD optical transceiver

Join us on the journey towards lightning-fast speeds with our latest Vitex Talks video! In this episode, we’re excited to introduce our new 800G QSFP-DD optical transceiver, designed to take your network speeds to the next lane in the Internet Superhighway! While 400G speed lanes are still commonplace, the demand for faster speeds continues to grow, making the upgrade to 800G an essential investment for everyone who wants to stay ahead of the curve. Our 800G QSFP-DD optical transceiver are at the forefront of this trend, offering high performance, efficiency, and reliability.

Hey everybody, this is Craig. I’m just driving down the Internet Super Highway to tell you about a new awesome Vitex product that’s coming out to just do like a spotlight. So, what we’re going to do is we’re going to shine some light on 800G transceivers. Before we jump into that, let’s just take a little trip down the old Internet Super Highway.

The Internet Super Highway

So, as we move into the future, of course the one thing we’re going to want and we’re going to need, we’re going to see a development of faster and faster technology. So, currently right now we’re in this 200 and 400G speed. We’re just coming out with 800G and 1.6 tera is being developed and in the future we just, you know, see this continuing to go, right. So, we’re going to move into 3.2, 6.4 tera and it’s just going to keep going and going and going, right. So, the need for faster and faster devices doesn’t look like it’s going to slow down any time in the future. But not all people in all applications need this speed. Some tools and some solutions are perfectly fine in the slow lane and they don’t have to be all the way in the fast lane. But for those applications that need to be in the fast lane, what’s driving some of that stuff?

What is 800G used for?

So, let’s just kind of take a look at where 800G is really going to be used for. So, we see a lot of push as cloud solutions are growing. Getting storage, accessibility. There’s going to be more development in the hyperscale data centers. So, there’s going to be a lot of work there that’s going to push towards 800. Additional things such as artificial intelligence, machine learning, also, into gaming and use of things in virtual reality augmented reality. And as we saw during the pandemic, there was a lot of push from home. So, that’s something that we’re looking for in the future is how that’s going to change. How workplace and institutions such as like universities and offices are going to change. And more of that access for faster data rates are going to be needed outside of the office, outside of a campus type setting. So, as we progress through the last couple of years, where do we see this breakdown of 400G and 800G and where is it going forward?

So, right around now, the majority player is still 400G, right? There’s only a little percentage of 800G products out there, but that’s changing this year. So, also, here on Vitex, we’re coming out with our 800G products in 2023. And as we move into the next couple years, we see this big shift going on where 800G is definitely going to be the dominant player.

How did we get here?

So, we understand who’s driving down the highway, how we’re getting there, but what type of technology brought us there? So, if we just kind of take a step back from this and look at when we were in the 25G lane how we would move to an 800G product, right? So, how does something like the QSFP 112 or the QSFP double density 800 MSAs come into play? So, there’s really three options of how we move up in this speed. So, our first one is board rate, right? So, we can move from 25G to 500 to 100G per lane. So, every time we do something like that, we get a multiplier of our rate. Also, our second option is modulation. So, having a non-return to zero and then going to a PAM-4. So, when we go to a PAM-4, we also get a nice multiplier of our data rate as well. And the last option we have is the physical amount of lanes. So, what’s in our physical link, right? We move from single link to four lanes, and then we continue into an eight lane. And we see that multiplier also, continue to happen. So, a whole combination of those bring us through from our starting at around 100 all the way down to how we get to 1.6 terabyte.


And so, if you have a need for an application if you’re in one of these high performance computing, you’re in a data center space, if you’re in any of these other players that are looking to get into the fast lane, contact us here in our New Jersey office. We can definitely provide a solution for you. And so, until next time, I’ll see you then.
