The optical network sector, which rallied strongly late last week while the market was headed south, has reversed course.
FORBES: Optical Stocks Slide On Ciena's Weak April Quarter Outlook
TeraGrid's partner sites are connected by a dedicated optical network that zaps data around at ten to 30 gigabits per second.
The hefty price tag is owed to the fact that SDL's technology lies at the heart of the white-hot optical network market.
It's named after their night-sky survey program, the International Scientific Optical Network.
This will establish a truly meshed optical network, ensuring world-wide coverage at service levels and connectivity options previously unattainable by other satellite platforms.
FORBES: Star Wars 2.0 - Lasers To Extend Fiberoptic Networks To Space
Metro networks have phone gear like digital cross-connects, which manage high-and low-speed traffic, and synchronous optical network (Sonet) systems, which come from fiber-optic phone networks.
The comet, discovered by Vitali Nevski and Artyom Novichonok and named for their institution, the International Scientific Optical Network, is still distant: 793 million kilometres away.
The advantage of the rival NTT technique, says Saruwatari Masatoshi, a senior researcher at the company's Optical Network Systems Laboratories, is that it uses only a single light source.
Crosswave uses synchronous optical network (sonet) and wavelength division multiplexing (dwdm) technologies, which enable it to transmit data at high speeds over long distances with a high degree of reliability.
And the product examples you cite attest to Alcatel's U.S. market leadership in the fast-growing optical submarine network, ADSL broadband Internet access and digital-loop carrier product areas.
The optical fibre network at the heart of the effort makes use of the same types of fibres that transmit data to homes and across oceans, in which light bounces along the fibres' length.
Building a unique global network of optical fiber, they learned the perils of debt in a deflationary market.
Around EUR 6 billion is earmarked for rolling out the broadband infrastructure in the German fixed network with optical fiber and vectoring between 2013 and 2020.
ENGADGET: T-Mobile and Apple sign agreement to launch products in 2013
The standard's global deployment is pervasive, and the span of stakeholders in its ongoing development is sweeping, including network component and system manufacturers (optical transceivers, cabling, integrated circuit, powering devices, switches and network interface cards, for example) and network, software and bandwidth providers, as well as LAN and Internet users worldwide.
ENGADGET: Ethernet gets new IEEE standard, still requires your thumbnail
China Unicom recently gave Lucent a billion-dollar contract to design and deploy an entire network, from the optical backbone to the circuits and wireless systems that will feed into it.
While Wall Street body-slammed the company for one lackluster quarter, in that same period sales of Lucent's most advanced optical gear doubled, and its data network business grew 60%.
Investors are clearly believers in large part because of the track record of Corvis' founder, David Huber, who also started Ciena (nasdaq: CIEN - news - people), a pioneer in new optical technology now used in nearly every telecommunications network.
The prevailing conventional wisdom was that the whole network would have to be replaced with optical fiber to enable video transmission.
