Connection of the fiber on the MA5616

3

One end of the fiber is connected to the optical port of a board on the MA5616, and the other end is connected to an optical distribution frame (ODF) or the optical port of an upstream device or other devices.

Fiber connections of TN12OAU boards
One multiplexed optical signal received at the IN port is sent to the EDFA optical module. The EDFA optical module amplifies the optical power of the signal and locks the gain of the signal. The signal is then transmitted to the DCM board through the TDC port for dispersion compensation. Then, the signal is sent back through the RDC port. The amplified multiplexed signals are output through the OUT port. The multiplexed signal can also be input through the VI port and output through the VO port after the optical power is adjusted. Then, the IN port receives the multiplexed signal sent from the VO port.

Whether ODUk SNCP protection switching will fail if logical fiber connections and physical fiber connections are reverse
Yes, ODUk SNCP switching will fail.

Fibers connected using SFIU boards
Each port on the SFIU board supports bidirectional transmission. It can receive or transmit a signal depending on the position of the SFIU board. The optical ports LINE1, LINE2, SYS1, and SYS2 can be used to transmit or receive signals on the main optical path.
