1. Including connectors' loss. The IL increase from low frequency channel to high frequency channel for Demux; it reverse for Mux.

2. For 8 Ch: It skips 2 channels from the edge channel of Mux/Demux for the wavelength range of upgrade port.

For 16 Ch: It skips 2 channels from the edge channel of Mux/Demux for the wavelength range of upgrade port.
