ROADM Vendors Perk Up

Business is finally arriving for hopefuls in the reconfigurable optical add-drop multiplexer (ROADM) market, as carriers have put out requests for proposals (RFPs) specifying the technology.

Money is back, too, as startup Polychromix Inc. announced an $8 million funding round earlier this week. This second round is intended to take the company into volume manufacturing (see Polychromix Raises $8M).

Other ROADM startups also say the market is picking up. Next week, Lynx Photonic Networks, will announce several new OEM partners, including two large distributors in Asia, South Korea-based 4urnet and Taiwan-based BBN. Lynx founder and CEO Daniel Tal says activity from carriers is building.

The ROADM adds the promise of flexibility to Wavelength Division Multiplexing (WDM) networks, allowing operators to remotely change the way wavelengths are taken in and out of a particular optical switching node. Older OADMs can't do this without being manually reconfigured, requiring the dreaded "truck roll." ROADMs can thus reduce operating expenses for networks.

More than 20 vendors, including Polychromix and Lynx, are developing the key components and subsystems for ROADMs. Many of the players are startups still hoping to get their first big sale, but the field also includes such big names as JDS Uniphase Corp. (Nasdaq: JDSU; Toronto: JDU) and Avanex Corp. (Nasdaq: AVNX).

The good news is that the business is finally arriving, something vendors had anticipated late last year (see ROADMs Could Boost Components). AT&T Corp. (NYSE: T), MCI (Nasdaq: WCOEQ, MCWEQ), SBC Communications Inc. (NYSE: SBC), and Verizon Communications Inc. (NYSE: VZ) have all put out RFPs specifying ROADM technology, and analysts expect cable operators to start building with ROADMs as well (see Siemens Has Hopes at AT&T and MCI's on a New Wavelength).

"If you look at the RFQs [requests for quotes] today -- not just the 'fishing' RFQs -- they're all demanding reconfigurable OADMS," says Mouli Ramani, vice president of marketing and business development at Polychromix.

Other executives concur. "We're seeing a nice pickup in the need for wavelength services and optical protections," says Tal.

Tal says Lynx has raised more than $60M and still has much of it left, as the company never had more than 100 employees and now has 60. "We could last until 2007... if we all went on vacation," he says.

Nice work if you can get it, but Tal said he has no such plans for a vacation. He says the company's line of optical switches, called LightLeader, allow for "plug and play" reconfigurability. These reconfigurable subsystems can be installed to upgrade static optical switches to an ROADM.

So, the players in the ROADM market have a story. The downside is that ROADMs aren't yet needed in huge numbers.

"The long-haul ROADM market is happening now. But requirements for ROADMs in a long-haul network are not huge, with maybe 50 to 150 points in a national backbone where they are necessary right away," says Scott Clavenna, analyst with Heavy Reading, the independent research division of Light Reading Inc. "For metro, which should kick in [at the] end of this year or next year, volumes are higher, but still limited."

The ROADM craze started during the bubble but got stalled by the recession, leaving startups holding their breath waiting for recovery. Naturally, some couldn't outlast the drought. Systems vendor Innovance Networks shut down, becoming one of Light Reading's 2003 Top Ten: Startup Flameouts, and Corning Inc. (NYSE: GLW) axed its Fountain Valley operation. The latest casualty appears to be components firm Clarendon Photonics Inc. (See Headcount: Company Makeover, Corning Chops Wavelength Blocker, and Headcount: FCC Eyes Action Jackson.)

While not revealing any customers, Polychromix claims to be gaining traction. "We have a few Tier 1 system houses that are in the near term going to be working with our wavelength blockers in their equipment," Ramani says. Production versions of that equipment should be appearing in the second half of the year, he says.

Polychromix's components use micro-electromechanical systems (MEMS) technology, an approach also employed by LightConnect Inc., NP Photonics Inc., Silicon Light Machines, and others. Other technologies being applied to ROADMs include thin-film filters, liquid crystals, and micro-ring resonators. Light Reading plans to summarize these efforts in an upcoming "Who Makes What" report.

re: ROADM Vendors Perk Up Guys have you checked CernoluX Tunable Opticla Add Drop Multiplexer..Looks like a great hit!

re: ROADM Vendors Perk Up Since the ROADM is taking up, how's the market space for MEMS switch?

re: ROADM Vendors Perk Up The ROADM market picking up could be good news for small metro-box makers like Tropic and Photuris. Arroyo wasn't mentioned in the article but are probably also excited or hopeful about ROADM sales sparking up. Every small company needs revenue these days.
- the wrong opinion

re: ROADM Vendors Perk Up Carrier interest in ROADMs must be good news for some systems vendors, but for which components vendors is this likely to be good news? In other words, how many of the likely systems vendors are using ROADM subsystems from these component vendors, and how many are using "in-house" components? Of the listed components vendors, how many (and which) are actually included in designs being considered for these bids?

re: ROADM Vendors Perk Up Right on.
Apart from the start-ups willing and trying to hype their product before OFC, it would be interesting to find out the actual demand or need for ROADM from carriers and which systems vendors are really including the ROADMs.
At one point in time Siemens and Alcatel were looking into it.
As mentioned, Corning pulled out and JDS has a product. Emerging systems vendors talk about it in their presentations but do they have actual +ve responses for new deployment (Movaz is the only one so far making inroads)

re: ROADM Vendors Perk Up Look to Fujitsu to lead in this market when it takes off. They continued to develop their product right through the tough times. Supposedly rock solid and making inroads.

re: ROADM Vendors Perk Up ROADM's sound good.. but a a few gotchas...

Initial deployment is a little expensive.. and the control / management / monitoring / provisioning of the wavelengths is the required "extras" to make it in the real world.

As for the vendors....:

A little thing about Movaz.. They tried in SBC and got their collective butts spanked due to the "quality" of their product. Sounds like they were pushing the timeframe and got caught with a not ready for prime time product.

Fujitsu is a question in terms of the overall product availability and "in-roads" to sales.

Photuris..? how many employees now? blub.. blub

Tropic..? Other than the LR adds.. no announcements..

Arroyo..? component vendor only by their web page.. sorry. you need a system guys.. you know the other bits to go along with the secret ROADM box..
