Fujitsu Labs adds processing to boost optical reach

Fujitsu Labs has developed a compensation technique that tackles non-linear effects in a coherent receiver-based optical transmission system. The technique promises to boost the reach of 100 Gigabit-per-second (Gbps) and future higher speed systems.

“That is one of the virtues of the technology; it is not dependent on the modulation format or the bit rate”

Takeshi Hoshida, Fujitsu Labs

Packet optical transport: Hollowing the network core

Intune Networks has developed an optical packet switching and transport (OPST) system that effectively turns fibre into a distributed switch.

The platform enables a fully-meshed metropolitan networkIntune Networks' CEO, Tim Fritzley (right) and John Dunne, co-founder and CTO with software support for web-based services, claims the Irish start-up. 

“What we have designed allows for the sharing of the same fibre switching assets across multiple services in the metro,” says Tim Fritzley, Intune’s CEO.

The company is in talks with several operators about its OPST system, which is being used for a nationwide network in Ireland. The system is also part of an EC seventh framework project that includes Spanish operator Telefónica.

Is Broadcom’s chip powering Juniper’s Stratus?

Briefing:  Data centre switching

Part 1: Single-layer switch architectures

Juniper Networks’ Stratus switch architecture, designed for next-generation data centres, is several months away from trials. First detailed in 2009, Stratus is being engineered as a single-layer switch with an architecture that will scale to support tens of thousands of 10 Gigabit-per-second (Gbps) ports.

Stratus will be in customer trials in early 2011.
