Sonet: Who's Ahead in Long Haul?

Cisco Systems Inc. (Nasdaq: CSCO) announced yesterday that it's leading the North American market for long-haul Sonet OC48 products, based on figures from RHK Inc. The figures were published in the market research firm's January 2001 report, "SONET Transport and DCS Long-Haul SONET Market Forecast." OC48 links support 2.5-Gbit/s in carrier networks.

North American Long Haul Sonet OC48 Market Cisco's announcement is interesting for several reasons. First, it demonstrates the priority Cisco's assigned to gaining a significant toehold in the market for mainstream carrier equipment, a market the company entered seriously less than two years ago with its acquisiton of Cerent Corp.

But Cisco also has raised a bit of confusion. That's because the success of Cisco's Cerent box, now dubbed the ONS 15454, has been chiefly in network edge applications, not in the long-haul part of the net. The ONS 15454 was among the first products to aggregate OC48 links and feed them from carrier points of presence (POPs) to the network core.

It's also notable that Cisco's announcement this week didn't mention a number of other interesting points from RHK's report. For instance, RHK's figures show Nortel Networks Corp., the overall Sonet market leader, breathing down Cisco's neck in long-haul OC48. Just three points separate the two companies' slices of the OC48 pie.

What's more, RHK's report indicates that Cisco's not leading the most lucrative segment of the North American long-haul Sonet market. Sales of Sonet OC192 (10 Gbit/s) gear were $2.763 billion of an overall market of $5.03 billion in 2000 -- more than the $1.944 billion for OC48 (although more OC48 ports actually shipped). And RHK says that OC192 is the fastest-growing segment of the long-haul market.

What's more, Cisco's not on the map at all when it comes to sales of Sonet OC192 links, according to RHK. Instead, Nortel sales account for 95.1 percent of that market, with the rest of the pie divvied up among other players in tiny slivers.

North American Long Haul Sonet OC192 Market Neither Cisco nor Nortel seems eager to emphasize these points -- for different reasons. For its part, Cisco doesn't yet support OC192, and understandably eschews discussing the potential of that market. "We don't talk about unannounced products," a spokesperson says. And although Cisco's talked for months about adding OC192 to the ONS 15454, nothing has materialized so far.

Some analysts other than RHK say Cisco needn't worry too much about OC192 in the metro space -- where its OC48 presence is strongest. "OC192 isn't big in the access space," asserts Seth Spalding, director at Epoch Partners. He says some vendors, such as ONI Systems Inc. (Nasdaq: ONIS), offer OC192 as an access option, but he doesn't foresee it taking off there for at least a couple of years.

For its part, Nortel seems to view its leadership in long-haul Sonet OC192 links as a mixed blessing. That's because Nortel would rather publicize figures that show its role in next-generation products via sales of DWDM (dense wavelength-division multiplexing) gear. Ironically, Nortel gave a mixed message last week in announcing its market share in DWDM (see Nortel: Top Dog, but for How Long?) -- just as Cisco did with RHK's figures this week.

In both cases, attempts to pin down one aspect of the market served to emphasize a larger, more complex picture that wasn't initially discussed.

re: Sonet: Who's Ahead in Long Haul? Funny you should say that. Nortel gained its massive DWDM and OC-192 market share with a not-so-savy provisioning tool. In fact, you fail to realize that Nortel has gained its hugh market share with the same lame software accross the board! What will win is the product which is sold like hell. Cisco had one major carrier convinced to buy a boat load of their product before it even came out!

Superb provisioning software does exist on the Fuji FLM2400 - but they hit the rocks against Nortel a long time ago. Cisco has their great provisioning software - but that's only an enabler.

However, they will not emerge as the winner after the OC-48/OC-192 window is closed (soon). What is winning now are "true next-gen" products.

Will bandwidth play second fiddle? Perhaps what you are trying to say, or should have said is that what will win in the metro edge is a core product. OC-48s and OC-192s don't do it for managing circuits. Cisco and Nortel don't have anything now and are getting vested by Ciena - again. (should have bought them at 17!)

Another thing that Nortel has above anyone else is network management software - par excellance. But it won't help when you aren't hitting the needs of the moment.

re: Sonet: Who's Ahead in Long Haul? A note to all:

1) We all know the difference between a field and a lab test.

2) Please MENTON exactly who these mysterious core router manufacturers are that have been cut out. (and a note to CORVIS-wavelength switches don't count- it doesnt even have the density to be called a switch for that matter).

3) If these ephemeral core manufacturers actually have a deliverable product, then send a couple of boxes to LR with 200 to 800 line cards (and see if management will sign off on tieing up 90 days inventory) and stop complaining.

re: Sonet: Who's Ahead in Long Haul? This might actually be over 90% of the core market, but that is not the point. There are other players who compete with these guys, many who have products shipping in volume.

Point is, if there are other companies who want to (or should) be tested, can these be tested in the future? Unless there were interoperability tests, then given scientific rigor which demands repeatability, can these other boxes be tested identically?

re: Sonet: Who's Ahead in Long Haul? Seems like the article tries to bring Cisco's claim into question - or diminish its importance in the overall optical networking picture. Fair enough, but don't take your readers for fools. Wasn't long ago <not all!="" at="" long=""> that the consensus seemed to be that "Cisco can't do optical - won't be able to."

I think Cisco has something to crow about here. Seems like a steep curve they're on - who knows what they may bring forth to this highly contested market. Wouldn't serve one to cover one's eyes.

Except for the gentleman who sizes things up relative to his grandmother's drawers - son, you should have turned away from that sight.</not>

Metro: Nortel v ???
Switch: Tellabs or Tellium v ??
Core Router: Juniper v ??

re: Sonet: Who's Ahead in Long Haul? "Yes, but do you always drop OC 192 / OC 48 using an ADM? I though that was the whole point of these new o-e switches that scale from DS 3 to infinity and beyond.

And this gets back to how you define the SONET market. Plus, any operator will tell you the first thing they want to do in the core is replace the ADM with a hybrid aggregation and/or cross connect (ie, intelligent) box.

If you really want to save money, make an ADM that drops lightwaves, does the O-E, sonet mux/dumux, and drops at DS 3 and OC 3."

Yes, you're right. but we were discussing about the article which is based on sonet products only.

Well, i really think that it will take a couple of years to have really transparent optical Networks.

What is sold in most of the proposals are SONET/SDH Equipment and DWDM is just something to enhance the use of the fiber, it's not used as a technology that could be rate and protocol independent.

OADMs are not as used as we would like to be.

re: Sonet: Who's Ahead in Long Haul? I think 90+% of this technology is here today, but it's certainly not free! One would have to expect a box with these features to carry a slight premium over a traditional SONET or DWDM box, depending upon what is actually integrated.

Take a look at Metro Optix, they appear to be the only company that has actually released a product that is very close to an "all-in-one" type solution, the backplane throughput is something like 820Gbps. I am aware of a few others out there as well: Akara, Tropic Networks and Caspain-to the best of my knowledge these guys do not have a released product---maybe someone knows differently and can share the news.

I think it is quite obvious that the optical networking industry is clearly headed toward (and needs) true optical multiservice platforms that can accomplish Layer 3 routing (at a minimum)and varying protocols without the requirement of a router, or other device sitting in front of, or behind the box...

re: Sonet: Who's Ahead in Long Haul? In addition to a system that seamlessly grows from DS3 to OC768, would you like IP/ATM/GigE functionalities ? In addition, would you like the best densities at each of these traffic levels ? Oh, yes, a modular WDM feature + an elegant provisioning system would be easy to add on.

And while I am building this all-in-one-panacea, would you like it for ... say, free ?

As an established equipment vendor who has seen several startups hype their messages with phrases such as the one in this thread, I am curious to find out from dabomb and glassman if you have seen a company deliver a manufacturable product such as the one above? Please educate.

re: Sonet: Who's Ahead in Long Haul? guy,

You are so out to lunch...one wonders if you have ever been in the real telecom industy.

You have so many errors in your claims. I will only address one or 2. First, Rockwell NEVER had an OC anything system. They did make some optical terminals...but they were way prior to SONET even existing as a standard let alone a product. That Rockwell group became a part of Alcatel and Alcatel did and does do SONET systems.

Second...you need to go visit your friendly RBOC....to see how large Fujitsu's market share really is. Admittedly, Fuji is late to the long haul space with OC192 and dense long haul DWDM....but in Metro Sonet...they have both the largest installed base and the largest ongoing revenue and ports shipped even now.

Learn your business before you make such uninformed comments. Useless waste of server space and time.

re: Sonet: Who's Ahead in Long Haul?
An ADM is an expensive piece of equipment that most operators would like to see combined with other equipment.

If you cant follow that, or you're not familiar with the cerent or K2 box, maybe YOU should brush up.

And another thing, there's nothing more IRRITATING than listening to a sales engineer say you have to buy the transmission and ADM from the same f--ing vendor, and STILL have to drop/mux the signal to get your customer's traffic.

re: Sonet: Who's Ahead in Long Haul? Hey Telecom_Guy,

This article is about market share, i.e. the amount of revenue vendors brings in divided by the total market. This has nothing to do with having the best technology.

This is the United States and we all know that a company's real worth is tabulated at the cash register. For all you out their making the better mouse trap, be warned - it's not about having cool technology, it's all about serving your customer's needs and by how much money you make at the end of the day.

Going back to the problems of this article, please understand this - the market shares presented here and in Cisco's press release do not include the Metro SONET market (which came in at $5.4B in 2000 according to RHK's Metro SONET report).

Cyras / Ciena does not show up in this report either - the only small start up to make it is Astral Point.

If Mary or someone else would look into this, maybe we can find out who the total SONET market leaders really are.

re: Sonet: Who's Ahead in Long Haul? Let's keep our eye on the ball, folks. It's about providing service provider customers with an aggregation / migration solution for Metro SONET /Optical deployments.

re: Sonet: Who's Ahead in Long Haul? The article was mentioning the revenues of 2000 ($1.9Billion). So it's not looking at already installed market share, but new revenue. Specifically the one for 2000. Although Fujitsu has alot of old equipment still out there, it's not getting the 49.3% the angry Fujitsu people claim on this board. I agree with the 2% or less figure. Fujitsu is "El Stinko". That's the technical term for their products. And another guy talking about Ciena's absence... Are they smoking something over there? Since when has Ciena had a huge share of OC48 sales / revenue. They only recently acquired Cyras. Even then I think they have separate booths at OFC. And as for the Optera guy that mentions the Nortel lead in the OC192, well that part is true. Everyone is trying to catch up, but once they do, it won't be hard to beat that slow turtle. They product is huge!! But I guess you have to buy what's available no matter what it looks like. Anyone remember those huge Rockwell OC12 nodes? LOL Well that's how I see the Nortel OC192. A switching fabric card the size of my grandma's drawers. Can't you guys at Nortel get with it and desgn a smaller switch fabric? And siemens? Well what can one say about a dinosaur.

re: Sonet: Who's Ahead in Long Haul? Mary,

You're making the same mistake the Cisco press release makes - you are leaving out the Metro SONET market.

RHK released the SONET Metro Market Forecast & Analysis yesterday, and the information was not included in the Cisco press release. If you read the press release closely, RHK analysts are quoted about the Long-haul SONET market. Cisco (and you) are extrapolating this over the entire market.

Could you PLEASE read RHK's Metro report, calculate the REAL OC-48 market and then write the article?

Otherwise, you're doing a real dis-service to other OC-48 vendors (especially Fujitsu which has 43.9% share of the OC-48 metro SONET market).
