O- and E- Band Interleavers
Optoplex’s Optical Interleaver products are based on our patented Step-Phase Interferometer design. Used as a Demux (or Mux) device, an optical interleaver separates (or combines) the Even and Odd channel signals (see the schematic diagram below). Each optical interleaver device is optimised to cover either C-, L-, O-, or E-band wavelengths, with the option of covering C+L band. The current optical interleaver product family supports 100-200, 50-100, 25-50 GHz channel spacing, as well as other custom channel spacings. The Demux and Mux interleavers can be effectively co-packaged into a single box for easy handling and cost-saving. Dual-stage optical interleavers (such as 25-100 GHz) and asymmetric interleavers (Even and Odd channels have different passband widths) are also available.Features
