Finisar adds silicon photonics to its technology toolkit

• Finisar revealed its in-house silicon photonics design capability at ECOC
• The company also showed its latest ROADM technologies: a dual wavelength-selective switch and a high-resolution optical channel monitor.
• Also shown was an optical amplifier that spans 400km fibre links 

These two complementary technologies [VCSELs and silicon photonics] work well together as we think about the next-generation Ethernet applications.

An interview with John D'Ambrosia

The chairman of the Ethernet Alliance talks to Gazettabyte about the many ways Ethernet is evolving due to industry requirements.

"We are witnessing the evolution of Ethernet in ways that many of us never planned because there are markets that are demanding different things from it."

Module makers rush to fill the 100 Gig mid-reach void

You may give little thought as to how your Facebook page is constructed each time you log in, or the data centre ramifications when you access Gmail. But for the internet giants, what is clear is that they need cheaper, higher-speed optical links to connect their equipment that match the growing size of their hyper-scale data centres.

Ciena adds software to enhance network control

Engineers at Ciena have developed software to provide service providers with greater control over their networks. The operators' customers will also benefit from the software control, using a web portal to meet their own networking needs.

"Networks can become more dynamic," says Tom Mock, senior vice president, corporate communications at Ciena. "Operators can now offer more on-demand services." If much work has been done in recent years to make the network's lower layers dynamic, attention is turning to software to make the networks programmable, he says.

10 Gigabit Plain Old Telephone Service

Bell Labs has sent unprecedented amounts of data down a telephone wire. The research arm of Alcatel-Lucent has achieved one-gigabit streams in both directions over 70m of wire, and 10-gigabit one-way over 30m using a bonded pair of telephone wires.

Keith RussellThe demonstrations show how gigabit-speed broadband could use telephone wire to bridge the gap between a local optical fibre point and a home. The optical fibre point may be located at the curbside, on a wall or in an apartment's basement.    

Service providers want to deliver gigabit services to compete with cable operators and developments like Google Fiber, the Web giant's one-gigabit broadband initiative in the US. Such technology will help the operators deploy gigabit broadband, saving them time and expense.

EZchip targets multi-core processing with Tilera purchase

Network processor specialist, EZchip Semiconductor, is to acquire Tilera. The deal is valued at $130 million in cash: $50 million when the deal closes, and up to $80 million more depending on performance targets being met. 

Bob Wheeler, The Linley Group

Tilera's products include multi-core processors, intelligent network interface cards (NICs) and one rack-unit (1RU) network - 'whitebox' - appliances used for security applications.

Acquiring Tilera will broaden EZchip's market. Tilera's devices are used for network appliances, enterprise routers, cloud computing, video and voice encoders, security, deep-packet inspection, load-balancing, and emerging applications such as software-defined networking (SDN) and network functions virtualisation (NFV). 

EZchip's first acquisition will also broaden the company's US presence and customers: Tilera has 100 customers including Brocade, Check Point Software Technologies, Cisco, Fujitsu, Harmonic, MikroTik and ZTE.
