Alcatel-Lucent Adds Depth to Its Metro Lineup

Alcatel-Lucent is the latest vendor to raise the stakes in the increasingly contentious metro optical poker game, announcing Thursday that it's adding a new box to its metro platform family and releasing next-generation versions of two other boxes in its metro lineup.

The new addition to the 1830 Photonic Service Switch platform is the 1830 PSS-8, the numeral alluding to the 800 Gbit/s switch capacity in a three-rack-unit deployment of the four-slot chassis. Alcatel-Lucent (NYSE: ALU) also has new versions of its 1830 PSS-4 (400 Gbit/s) and 1830-PSS16 (1.6 Tbit/s), with all three boxes employing the same software release. (See Alcatel-Lucent Expands Metro Optical Family.)

The distributed switching capability and footprint size (smaller than the PSS-16, but bigger than the PSS-4) of the PSS-8 positions it well for metro aggregation and access applications, Kevin Drury, IP transport marketing lead at Alcatel-Lucent, tells Light Reading.

"Metro traffic is growing twice as fast as core backbone traffic, and up to three quarters of all the traffic that originates in the metro will stay in the metro," Drury says, alluding to Bell Labs research. "In the metro, you have requirements for platforms, as you go from metro core rings to the edge or aggregation area and down to small access points. Versatility is key."

The PSS-8 works the metro edge, where data center interconnect also is becoming a much-hyped application for a new round of dedicated products from a variety of vendors, including BTI Systems Inc. , Infinera Corp. (Nasdaq: INFN), Cyan Inc. and Coriant , the last of which just last week unveiled its 7100 Pico to attack the DCI use case. However, Drury emphasizes Alcatel-Lucent's platform breadth as its competitive edge.

Of course, the same vendors will launch or already have launched other products to fill out their own metro families to give network operators a greater array of options for supporting all architectures and applications. Infinera is expected to launch another metro product later this year, while Coriant's recent addition only deepened its existing platform family, according to Coriant CTO Uwe Fischer. (See Key SDN, Metro Steps for Infinera and SoftBank Choose Coriant for Metro.)

"It all depends on the type of operator," Fischer tells Light Reading. "Metro and regional can mean different things to different operators and can create a variety of footprint and distance requirements for both packet and optical services. Our Pico is not a new platform, but a variant and further downward extension of our 7100 Nano. But, we can also use our 7300 [Multi-haul Transport Platform] for a metro if the distance is much greater."

Re: Dedicated metro edge products Quite a lot of it is focused on the DCI opportunity, which carriers, vendors and analyst seen to agree is the initial use for 100G in the metro. Still hard to come to grips with real numbers around that specific opportunity, but vendors like Cyan and Infinera have targeted new products at DCI. ALU portrays its product is not being just for DCI, but of course they are clear about saying it's suited for that use case. They would be fools not to.

Re: Dedicated metro edge products How much of this business is about data center interconnects? There seems to be an explosion of network operator and service provider activity there.

Dedicated metro edge products Right now, the trend in new metro optical boxes is toward the edge--smaller units consuming less power and priced to be deployed in high volumes. ALU's next-generation PSS-16 make me wonder if we'll start see brand new (or new) generations of the larger metro core boxes, too.
