GouMax 4-in-1 tunable bandpass filter array consists of 4 individual 2-port tunable filter units. There are 4 input ports and 4 output ports. Each individual unit is 2-port voltage-controlled fiber-optic device. The product is designed using its proprietary micro-optics and tunable technology.

The filter passband shape is Gaussian. As schematically shown in Figure below for one 2-port tunable filter unit, when multiple DWDM channels are injected to the input port, the tunable filter selects one target channel to the output port and blocks all other channels. If the input is a wide-band spectrum, the tunable filter will select a target band for output and reject the rest band of spectrum.
