Ports of ITL boards
Ports of ITL boards include the following: TE (C_EVEN multiplexed signal) RE (C_EVEN multiplexed signal) TO (C_ODD multiplexed signal) RO (C_ODD multiplexed signal)

Functions of the ITL board
The ITL board is an interleaver to multiplex and demultiplex odd and even wavelength signals.

Signal flow on the ITL boards of OSN 8800 devices
The ITL board is used to multiplex and demultiplex odd and even wavelengths. The wavelengths from the RO and RE ports are multiplexed into one wavelength and then sent out through the OUT port. The wavelength from the IN port is demultiplexed as two wavelengths and sent out through the TO and TE ports separately.

Signal flows of the ITL boards on OSN 8800
An ITL board is used to multiplex and demultiplex the odd and even wavelengths. The wavelengths from the RO and RE ports are multiplexed into one wavelength and then sent out from the OUT port. The wavelength from the IN port is demultiplexed to two wavelengths and sent out from the TO and TE ports.

Functions of each port on the FIU board
An FIU board multiplexes and demultiplexes signals the main optical path and OSC signals. The RC port of the FIU board receives signals from the main optical path and the RM port receives signals from the OSC. The two types of signals are then multiplexed into one signal using the multiplexer module and are output from the OUT port. The IN port receives signals from the line and then sends the signals to the demultiplexer module. The demultiplexing module splits the signals into main optical path signals and OSC signals, which are then output through the TC and TM ports respectively.
