UMI Optical Interleaver



GouMax’s ITL-100 optical interleaver is a 3-port passive fiber-optic device that is used to separate Dense
Wavelength-Division Multiplexing (DWDM) channels into two groups of signal streams (odd and even
channels) in an interleaving way. GouMax’s optical interleaver uses an innovative design that features
wide stopband and higher channel isolation. It provides the best solution to expand wavelength channel
counts in DWDM system.

Traditional optical interleaver in the market has the limitation of 3-dB bandwidth (FWHM) being equal to
half of channel spacing (FSR) at each output port. Some high-performance applications require a wider
stopband to enhance the adjacent cross-talk performance. GouMax’s UMI technology can significantly
move the cross point of odd and even channels down at –5 dB or even –10 dB, achieving the much wider
isolation band. Furthermore, UMI optical interleaver has the sharp transaction filter shape. These distin-
guished features are critical for high data-rate optical communication network.
