Query board manufacturer information and check the description of the module. "Tunable" indicates that the wavelength of the optical module is tunable.
TI/R0 is connected to the client side, TO1/RI1 is connected to the client side of the working LWF, and TO2/RI2 is connected to the client side of the protection LWF.
For the feature code of a fixed-wavelength OTU board, the first 1 to 5 digits represents the wavelength. For example, 19300 indicates that the wavelength of a board is 193.00 THz.
The :ptp:Hexbid,b3,PP,YY;Hexbid represents the hexadecimal slot number. PP indicates the channel ID, which is 1 except the LWMR number, which ranges from 1 to 2. YY indicates the 320G wavelength number that ranges from 0x15 to 0x64.
