TMCORPORATION

Optical Interleaver
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 odd and evenchannel signals (see the schematic diagram below). Each optical interleaver device is optimized to cover
either C- or L-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 spacingsin that range. Dual-stage optical interleavers and asymmetric optical interleavers are also available.
