Huge opportunties seen for 40/100 GigE devices

LONDON — Market research group CIR, which focuses on optical components and optical communications, suggests the economic downturn will not delay early adopters of 40/100 GigE as companies such as Google and Amazon already have a "desperate need" for 100G connections.

CIR (Glen Allen, Virginia) added that even though the economic situation is having an impact on carrier network upgrades, scaling carrier networks to 100 Gbits/s will now only be accomplished using a 40/100-Gbits/s variant.

In its latest report, CIR says the market for 40/100 Gigabit Ethernet transceivers will reach $ 482 million in revenues by 2013.

The researchers suggests just a handful of firms are likely to shape the future of 40/100 GigE. These include Cisco, Juniper, Sun Microsystems, Force10, Nortel at the OEM level; JDSU, Finisar, Avago, Luxtera and Opnext at the transceiver level.

At the component level, the main players are likely to include Xilinx, Altera, IBM, LSI, Gennum, AMCC, Vitesse and Broadcom.

Though not mentioned in the CIR report, NetLogic Microsystems is also gearing up to be a major player, and was, late last year, angling to become the first company to sample a physical layer chip for the upcoming 40/100 Gbit Ethernet standard.

The adoption of 40G Ethernet is predicted to start in high end servers and High Performance Computing applications. Within the 40GigE environment, initially as much as 80 percent of the market will be accounted for by the SR4 version of the 40/100 GigE standard.

However, the SR4 version is expected to lose share to CR4 over time as 40-Gbits/s over-copper becomes more viable.

CIR expects both CR4 and SR4 to quickly lose share once serial 40GigE becomes a reality in 2014.

100G Ethernet is expected to be adopted initially in the core of the network, driven by growth in 10GigE server connections and access points.

And as 100GigE begins to generate revenues in around 2012, CIR expects the LR4 variant to account for maybe half the market, with SR10 taking another 20 percent of the market. However, improvements in copper technology should drive CR10 share of the 100 Gbits/s space to 25 percent or so by 2016.

The initial solutions for the 40G Ethernet CR and SR variants will, the researchers say, rely on existing technology leveraged from InfiniBand which should give vendors a faster time to market and reduced R&D costs.

The highest investment in new technology will come from the 100G LR and ER variants which require new 25G technology for the electronics and the optical components. This will include lasers, modulator drivers, PIN diodes, TIAs and SERDES technology. by John Walko

40Gb Ethernet set to be major feature at ECOC

LONDON — 40GbE transceivers and other parts, including testers, are set to be a major talking point at both the exhibitor stands and conferences at this week's European Conference and Exhibition on Optical Communication (ECOC) in Vienna, Austria.

Sumitomo Electric announced at the event it has started sampling to major potential customers a 40Gbit/s Ethernet transceiver module that it plans to start making available in volume during the second quarter of next year.

The company is demonstrating the device — that complies with the 40GbE standard under discussion at IEEE802 committee and which supports a 10km transmission distance — at ECOC.

The 40 GbE CFP transceiver uses a four wavelength CWDM laser diode with a low power drive circuit.

Sumitomo (Tokyo, Japan) says development of the part, and the work at the IEEE towards a 40GbE standard, has been driven by an anticipated infrastructure capacity shortfall as soon as 2010 due to the rapid growth of Internet services.

The IEEE 802.3 standard for 40/100G Ethernet has not yet been finalized. A lot of pieces of that technology still require significant work, according to presentations at an Ethernet Alliance meeting last week.

The company is also part of a multi source agreement (MSA) with other vendors supporting the CFP form factor for transceiver modules. The MSA for 40Gbit/s and 100Gbit/s pluggable modules is supported by Finisar, CoreOptics and Opnext, amongst others.

Finisar is also demonstrating at ECOC an operational Ethernet LR4 CFP optical transceiver transmitting data over 10 km of optical fiber that it claims will be the first demo of its type.

The demonstration will show Finisar's 40GE LR4 transmitting Ethernet traffic error-free over 10 km of single mode fiber. The device will be internally multiplexing four CWDM wavelengths running at 10.3 Gbits/s each. by John Walko
