Each CWDM channel has a +/-7.5nm channel width, while the High-Band is defined as the CWDM channel + 7.5nm while the low-band is defined as CWDM channel – 7.5nm. Within the High- or the Low-Band, there are total 16 DWDM channels, respectively, with a channel spacing of about 0.37nm. The MUX (or DeMUX) is based on optical interleaver and DWDM thin film filters. This configuration has wide operating temperature range (-40C to +85C) and superior performance, such as wide passband width, low insertion loss, high isolation, and excellent thermal stability, etc., over AWG technology.BBN International supplies Optoplex 5G PON MUX/DeMUX 50/100GHz Interleaver & 100GHz DWDMs
Product Description - Co-Packaged Optical Interleaver
Co-packaged interleaver consists of a pair of iterleavers in the same package. There are three input ports and three output ports. The interleaver pair may contain one interleaver (Mux) and one deinterleaver (DeMux), or a pair of (Mux) interleavers, or a pair of (DeMux) interleavers. Customers can specify configurations according to their design and applications.

Product Description - Switchable Optical Interleaver
In a switchable interleaver, there are two operation modes:
Mode A: All pass
Mode B: Interleaver
In Mode A, the system operates at any channel spacing, in which all channels pass through the device and output from one of the two output ports as if there is no extra device inserted. When the system is switched to Mode B, the device operates as a normal optical interleaver, such 50-100GHz interleaver. The working principle is schematically shown below.
In Mode B, the device could be a standard symmetric interleaver, or an asymmetric interleaver. Channel spacings are not limitted to 50-100GHz. They can be any frequency pair: between N-GHz and 2N-GHz.
