Santur delivers narrow line width, low noise widely tunable lasers suitable for coherent detection at 40G/100G — The world’s largest supplier of tunable solutions drives the transition to next generation networks by delivering high performance, low cost narrow linewidth lasers and modules

FREMONT, CA – September 2, 2008 – Santur Corporation, the leading manufacturer of high performance tunable solutions for the global telecommunications industry, today announced the availability of narrow linewidth, low phase noise, and high power DFB array-based widely tunable lasers. Such characteristics enable the efficient transition of networks to 40Gbps and 100Gbps rates by enabling advanced modulation techniques with coherent detection. In these applications, a DFB solution offers a number of benefits over other approaches due to the stability, ease of use, and lack of low frequency jitter associated with mechanical resonances.

The new tunable lasers complement Santur’s existing portfolio of tunable transmitters and modules. Similar to the approach at 10Gb/s, Santur is developing a portfolio of 40Gbps and 100Gbps products with tunability and flexibility to support diverse modulation schemes.

“This is a particularly significant step for our industry, because these types of specifications previously were only the domain of more complex external cavity devices. Now there is a more robust DFB-based solution that is intrinsically easier to use.” stated Bardia Pezeshki, CTO of Santur, “In addition to providing the standard precalibrated modules with electronics, the simplicity of our technology allows our customers to buy at the lower cost butterfly level and adapt it for their application without fear of mode-hops or cavity instabilities.

Santur is providing customers with devices rated at 30mW and 40mW optical power, typical linewidth of 250 kHz and instantaneous linewidth of about 100kHz. The lasers are widely tunable over C or L band and are available in butterfly or module form factors. These solutions offer unprecedented cost advantage and carrier proven DFB robustness to enable system integrators to upgrade to higher line rates by adding a new linecard to currently installed equipment while maintaining network stability and architecture.

Santur will be showcasing its focused portfolio of solutions at ECOC 2008 in Brussels, Belgium. Santur representatives will be at booth #18M from September 22-24.
