In general, the NG WDM signal flow is as follows: line board -> multiplexer board -> OA board -> FIU board -> peer FIU board -> peer OA board -> peer demultiplexer board -> peer line board.

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.

OSN 8800 boards that support physical-layer clock signals
All boards of the OSN 8800 support the following operations on physical-layer clock signals: external frequency source access and internal frequency source transmission.

Whether there are wavelength conversion boards that support GE signals on the OSN 8800
Yes, the OSN 8800 provides wavelength conversion boards that support GE signals, such as LOG boards.

OSN 8800 boards that can transmit STM-64 signals
TDX or TQX.
