CoreOptics Inc., a leading designer and manufacturer of 10/40/100 Gb/s optical networking subsystems, today announced that it ranked number 107 on Technology Fast 500™, Deloitte LLP’s ranking of 500 of the fastest growing technology, media, telecommunications, life sciences and clean technology companies in North America. Rankings are based on percentage of fiscal year revenue growth during the five year period from 2004–2008. CoreOptics grew 1618% percent during this period.

As carriers seek to evolve their networks to 40 and 100 Gbps, new cost-effective ways to deal with the resulting signal impairment issues and the longer transmission requirements must be found.

The Optical Internetworking Forum (OIF; search Lightwave for OIF) has issued a framework document that spells out what it hopes to accomplish to aid the development of 100-Gbps long-haul DWDM equipment. The document not only explains the dual-polarization quadrature phase-shift keying (DP-QPSK) with coherent detection approach it has chosen as its focus, but highlights several implementation agreements and related project work.

CoreOptics Inc., a designer and manufacturer of 10/40/100 Gbps optical networking subsystems, announced the validation of the company's algorithm implementation and DSP architecture to achieve what the company said will enable the most inexpensive 40G transmission systems compared to currently available technologies.

CoreOptics Inc., a leading designer and manufacturer of 10/40/100 Gbps optical networking subsystems, today announced the validation of the company's algorithm implementation and DSP architecture to achieve what the company believes will enable the most cost-effective 40G transmission systems compared to currently available technologies.

CoreOptics coherent technology will enable cost effective transition for carriers upgrading backbone networks from 10G to 40G DWDM and sets the foundation for 100G optical networks.

Sierra Monolithics Inc. had a chip market all to itself at 40 Gbit/s, but the company is going to have to deal with more competition as the 100 Gbit/s generation comes along. The privately held company is trying to get a headstart, at least, having announced its SerDes chips yesterday. And that's why CoreOptics Inc. -- an optical subsystems vendor -- came out last June with its own 40 Gbit/s SerDes.

At its Q4 meeting last month, the Optical Internetworking Forum (search for OIF) announced a 100G Long-Haul DWDM Transmission Module project. In addition, OIF members approved the completion of SFI-S, an implementation agreement that defines a scalable interface between SERDES and Framer devices from 40G to 100G and beyond.

CoreOptics Inc., a manufacturer of 40 Gbps and 10 Gbps optical networking subsystems and ADVA Optical Networking (News - Alert) have jointly developed the second generation of 10 Gbps Maximum Likelihood Sequence Estimation (MLSE-2) technology based on ADVA Optical Networking’s FSP 3000 Wavelength Division Multiplexing (WDM) platform.

A product announcement from metro network equipment vendor ADVA Optical Networking and 10 and 40 Gbit/s subsystem developer CoreOptics highlights how vendors are finding new ways to collaborate. At the European Conference on Optical Communications (ECOC) here in Brussels today, the pair unveiled a jointly-developed optical module technology that could help to make it easier and cheaper to build metro ROADM (reconfigurable optical add-drop multiplexer) networks.

The financial environment in which optical communications companies operate offers a conundrum. On the one hand, market research indicates that more money is being spent on optical communications technology today than at any time since the height of the bubble in 2001. On the other, the balance sheets for companies active in the space don't reflect the kind of prosperity such customer spending would normally imply, particularly in the optical components and subsystems niche. Not surprisingly, the financial community doesn't like conundrums—so when companies go looking for venture funding, they'll find that while carrier capital expenditures have risen, venture capital (VC) expenditures have not.

By some accounts, only two-thirds of fiber currently in the ground will support 40-Gbit/sec transmission and even less will accommodate higher data rates, thanks to optical impairments caused by dispersion. Chromatic dispersion can be compensated using electrical or traditional optical techniques, including dispersion-compensating fiber (DCF) and tunable optical dispersion compensators (TODCs). But the effects of polarization-mode dispersion (PMD) are not nearly so easy to mitigate—either optically or electrically.

Like the prototype "cars of tomorrow" that always draw a crowd at the major auto shows, demonstrations of 100-Gbit/sec technology have proven a popular feature at communications trade shows this year. Prototypes on display at OFC/NFOEC this past February and last month's NXTcomm indicate that consensus on technology directions has begun to form in both the standards bodies and the industry as a whole.

Optical startup CoreOptics Inc. received $25 million in financing, which it will use to ramp up sales and marketing and increase its development of 40-Gbit/s subsystems.

SAN DIEGO -- OFC/NFOEC -- It's not quite like winning the Super Bowl, but Alcatel-Lucent (NYSE: ALU) appears to have claimed the championship for most 100 Gbit/s signals jammed onto a fiber.

In a post-deadline paper at OFC/NFOEC, researchers at CoreOptics (www.coreoptics.com), Siemens Networks/PSE (www.siemens.com), and the University of Eindhoven reported that they had combined coherent technology with DQPSK to transmit 10 wavelengths spaced at 50 GHz over 2,375 km at 111 Gbits/sec.

A pair of demonstrations reported in post-deadline papers underscored the potential of this technology. In the first paper, researchers at CoreOptics (www.coreoptics.com), Siemens Networks/PSE (www.siemens.com), and the University of Eindhoven reported that they had combined coherent technology with DQPSK to transmit 10 wavelengths spaced at 50 GHz over 2,375 km at 111 Gbit/s.

We see the 40 Gb/s deployment as more of a stepping stone, " says Saeid Aramideh, vice president of marketing for CoreOptics Inc. "Not that we have stopped our activity there, but certainly we see our future being 100 Gb/s based.

Schreiber compares selecting the appropriate EDC technology with buying a new car; there are high-end options and low-end options. On the high end are technologies like Maximum Likelihood Sequence Estimation (MLSE), the preferred digital equalization method of 10 Gbit/s transponder vendor CoreOptics (www.coreoptics.com)

CoreOptics is a fast-growing and innovative player in advanced optical networking subsystems.

CoreOptics GmbH, a German designer and manufacturer of optical networking chips and subsystems, closed a $28 million Series D financing as it contemplates going public in 2007 with the help of new lead investor GIMV NV.
