Operating system controls Raman
amplification
Software helps extend the transmission distances of optical signals between data centres up to 250 kilometres or more without the need for midspan optical amplifiers.
JDSU has integrated control software for Raman amplification within its AON Embedded Operating System (AON Embedded OS) The AON Embedded OS is used in circuit packs by network equipment manufacturers (NEMs) and service providers to manage optical functions as part of their dense wavelength division multiplexing (DWDM) network infrastructures

The new Raman control software helps to extend the transmission distances of optical signals between data centres up to 250 kilometres or more without the need for midspan optical amplifiers.
As companies increasingly use online applications to run operations, extending transmission distances with the JDSU Raman amplification technology may lower the chance of data loss from unexpected events such as power outages.
Extending transmission distances can also simplify ongoing operations and reduce costs for NEMs and service providers by removing the need to manage and house mid-span optical amplifiers.
Raman amplification has been successfully used in long-distance submarine network systems for several years, and has now evolved as a solution for underground network systems in the terrestrial market.
"The use of Raman amplification is growing in popularity because of its superior performance and ability to extend the distance of optical transmissions - this becomes even more important as faster 40G datarates take off", says Dave Nicholson, Senior Director of Research and Development in the Optical Communications business segment at JDSU.
"JDSU has designed its AON Embedded Operating System in a modular way so that we can seamlessly add new functionality like Raman amplification to take network infrastructures to the next level of efficiency".
Using Raman amplification, an optical beam travelling over a fibre interacts with shorter wavelength light in a process called "Raman scattering".
The Raman pump control software within the AON Embedded OS controls the pump lasers that amplify the optical beam.
Because of its special properties, Raman amplification can be generated in the transmission fibre over tens of kilometres, instead of confining the signal boost within specific amplifier sites, improving the optical signal-to-noise ratio (OSNR) within networks.
This allows optical wavelengths to travel over longer distances.
