JULY 28, 2008 -- Santur Corp. (search for Santur) has announced general availability of its 50-mW (17-dBm) C-band and L-band DFB-based widely tunable lasers.

The products are targeted at architectures where very high power and stable DFB characteristics are required. These applications include hybrid fiber/coax (HFC), cable TV, metro, PON, and backbone 40- and 100-Gbit/sec systems that are being developed with advanced modulation coding techniques or coherent detection. The lasers' very high power allows larger splitting losses in PONs and better signal to noise ratio in high-speed links, Santur says.

The Santur laser includes a wavelength locker for operation at 100 GHz to 25 GHz ITU spacing, and is available either as a butterfly or a fully contained precalibrated module. The lasers are fully qualified and extensively tested for telecom requirements with nearly 200,000 devices operating in the field carrying live traffic, according to Santur.

Vibha Goel, director of marketing at Santur, stated, "Our expertise in advanced DFB manufacturing techniques and our long experience with tunable lasers allows us to tailor the performance of the DFBs for various applications. We are proud to make 50mW widely tunable devices commercially available with no compromises on performance or power consumption."
