Wavelength tuning range of 5G OTU boards
LQG boards support wavelength tuning but OSN 8800 does not support 5G boards such as LQG boards. Therefore, no wavelength tuning for 5G boards is described in the OSN 8800 Product Description, but wavelength tuning for 5G boards is described in the OSN 6800 and 3800 Product Descriptions. For details, see the specifications of 5G boards in the OSN 6800 and 3800 Product Descriptions.

Whether the DCC channels of an SDH device can be disabled through OTU boards on an OTN device
GCC channels on OTU boards in OptiX OSN 6800 are electrical supervisory channels. The enable status of GCC channels does not adversely affect DCC byte transmission on an SDH NE.

Adjustment range of the 5 Gbit/s OTU boards
LQG support wavelength adjustment, but OSN 8800 does not support 5 Gbit/s boards such as LQG. Therefore wavelength adjustment in the OSN 8800 product description does not include 5 Gbit/s boards. For details, see the specifications of 5 Gbit/s boards in OSN 6800 and OSN 3800 manuals.

Port use of DCP boards on OTN devices
One DCP board is equivalent to two OLP boards, and two protection groups can be configured for the DCP board.

Optical ports of the OTU board
The OTU board provides two groups of optical ports: IN/OUT and Rx/Tx. The IN and OUT ports correspond to WDM-side input and output, and the Rx and Tx ports correspond to SDH-side input and output. The WDM side is also called the line side; the SDH side is also called the client side. In the alarm parameters, 1 indicates the WDM-side transceiver optical port, and 2 indicates the SDH-side transceiver optical port. In some documents, the optical ports of the OTU board are classified into system-side and line-side ports. In the early period, the system side is also called the client side.
