Chorum Technologies Inc.'s Polar-Wave family of optical products for terabit-scale active optical networks includes integrated optical systems, optical switches and processors, dense wavelength division multiplexing routers and interleave filters. The Optical Slicer 100G interleave filter slices incoming 100-GHz DWDM channels into two complementary sets of output spectra. The passive device can create flexible multinode all-optical rings. The Optical Slicer 100G features high channel isolation, making it suitable for demultiplexing applications.
