Nortel's HDX is Here

ANAHEIM, Calif. -- OFC 2002 -- Nortel Networks Corp. (NYSE/Toronto: NT) moved to silence its critics today by announcing that it is shipping the Optera Connect HDX optical switch.

In pure capacity terms, the product is impressive. Based on a switching fabric built with eight internally designed ASICs, the switch is designed to start at a 640-Gbit/s capacity and scale to a terabit using the same switching fabric. The line cards will also fit eight 10-Gbit/s ports each, say Nortel officials. Most line cards in optical systems these days only include four 10-Gbit/s optical ports.

In recent months, anticipation had been building about this large, do-it-all optical switch. Some analysts and the financial community have wondered whether Nortel could deliver the product on time -- and with the right customers (see Nortel's HDX: The Future Under Fire ).

On the face of it, the company looks to have gotten at least the first part right. The product is out in the first quarter of 2002, the original delivery date, and includes everything the company said it would.

"We've worked on this. Instead of making a lot of noise, we put our head down and we've delivered it on time," said Brian McFadden, president of Nortel's optical long-haul division, in an interview here with Light Reading.

On the second theme -- the customers -- Nortel may have some more work to do. The first announced customer is Touch America Holdings Inc. (NYSE: TAA), a Montana-based carrier focusing on broadband fiber networks. The emphasis here is on "CLEC," which these days might as well stand for "company losing economic cachet" (see Carrier Crisis: Who's Most at Risk?). The two companies did not release the terms of the deal.

A Touch America spokesman, Cort Freeman, said the company bought the product to consolidate a large collection of Sonet ADMs and digital crossconnects. He said the HDX will minimize the amount of labor inolved in manually managing that equipment, because the HDX allows those connections to be consolidated and provisioned electronically.

McFadden says Touch America is a good pick because it was the first company to buy Nortel's vaunted 10-Gbit/s technology several years ago. He also says they're "doing well."

The fact remains, however, that Touch America's stock was today trading on Wall Street for $3.33 per share and had a market capitalization around $350 million -- not exactly an AT&T Corp. (NYSE: T). Nortel will have to announce larger accounts to gain credibility with the product

So far, Nortel has announced that Genuity Inc. (Nasdaq: GENU) is one of the trial customers, and it says that it has another. This customer may be Bell Canada (NYSE/Toronto: BCE), according to a source inside Nortel's booth here at OFC.

Meanwhile, the optical switching space has cooled, as carriers cut back on large-scale optical projects. That may leave some people wondering if this massively scaleable optical switch is the right product for the wrong time. To Nortel's credit, that hasn't stopped other large players from moving into the market. Cisco Systems Inc. (Nasdaq: CSCO) was preparing an STS1 grooming switch; and, just last month, Lucent Technologies Inc. (NYSE: LU) announced plans for its LambdaUnite, an OEO grooming switch (see Cisco Preps Stealth Switch and Lucent's LambdaUnite Busts Out). That's in addition to optical switching pioneers such as Ciena Corp. (Nasdaq: CIEN), Corvis Corp. (Nasdaq: CORV), and Sycamore Networks Inc. (Nasdaq: SCMR).

Analysts have said the knocks against the HDX are the cost and size. Indeed, the size may be an issue. The product itself takes up two entire standard telecom bays -- although in its introductory configuration the bottom half of the two bays remain empty.

Regardless, the scaleability and flexibility of the product left McFadden feeling bullish: "You can use this to consolidate 16 bays of ADMs. That's the kind of business case that customers are looking for."

re: Nortel's HDX is Here The only people bashing the HDX are those who are fully informed about the products that they invest in.

re: Nortel's HDX is Here Yes the 10G is a deployed product and transmiting clear accross the country. BTW the Coorvis OCS has 16 10G's per shelf

re: Nortel's HDX is Here OS is OOO. HDX is OEO.

and yes the HDX is dwdm.

Has broadwing actually deployed the OS for 10G services or just 2.5G?

re: Nortel's HDX is Here aaaptics, I'm not aware of any issues at Genuity. I was simply pointing out that some people have been bashing the HDX because it's big. The Corvis article shows what "big" really is.

re: Nortel's HDX is Here Yeah, and CORV's OS is also already in commercial deployment in an all-optical network, and more importantly the new one (which is half the size of NTs HDX) will be available in Q2 '02.

So when does NT come out with a switch of comparable size? How about DWDM lol?

re: Nortel's HDX is Here If i'm not mistaken the HDX trials were with Qwest and Bell Canada. I haven't heard about Genuity yet. Anybody here can confirm that?

It's obvious now that the Ciena CoreDirector is under extreme pressure. And the thing is that most of the components in the HDX are Nortel proprietary, to be more specific from the Optical components division of NT. One of components is a multi-channel CMOS chip that has a total capacity of 100 Gb/s !!!! Where would Ciena get such a thing? It's pretty obvious that even if Ciena wanted to build something close to the HDX they couldnt because they just dont have the components.

I know that i may regret these words in the future but Nortel seems destined to recapture market share in the Long-Haul sector this year. Ciena will have a bad year , i think. Unless of course they have some new switch to compete , which doesn't seem to be the case.

re: Nortel's HDX is Here belzebutt, explain to all of us NT issues with the genuity tests.....what happened? you shouldn't be throwing stones in that BIG GLASS house of yours at NT....

Belzebutt 12/4/2012 | 10:45:57 PM
re: Nortel's HDX is Here If you think the HDX is big, check out the size of the current Corvis OS:

While the previous implementation took up four full seven-foot telecom racks and consumed over 3,500 watts of power, the newer version will occupy one rack and consume only 700 watts.

This is a 6-port switch! Sure, it integrates DWDM, but on the other hand it has no add-drop. If this is what the competition's power and size requirements are, NT is laughing.

re: Nortel's HDX is Here FMS is included. Like most high-capacticy equipment currently sold, it's a full rack deep, so it will be accessible from the back in any CO.

The layout has to do with the particular shape and arragement of the cards, it's a really unique product. All those who've seen it at OFC, you have to admit it looks pretty cool.

Yes, it does span the top half of two bays (with the bottom empty, so you can put other stuff there I suppose), but as you put capacity on the box you save a LOT of space compared to other products.

Go see the demo, you can see all that for yourself. For those who are at OFC, how close access do you get to the gear?

re: Nortel's HDX is Here Can anybody provide specific information about the physical dimensions of HDX.

Some HDX drawings show fiber management to the right of the system. I guess that would have to be included in the dimensions.

I have also read that the HDX needs to be accessible from the front AND the back. Is this true? WouldnGÇÖt that severely limit the places it can be installed in (e.g. not against a wall or back to back with other equipment). Or, is the HDX two bays wide AND two bays deep?

And the last question (referring to the LR article) is: Why does the HDX occupy more than one bay but in itGÇÖs smallest configuration only uses the upper half of the bays?

Here is a link to an HDX drawing (also showing the fiber management).
