Whether 1492-nm and 1511-nm wavelengths on the RM1 and TM1 ports of the ST2 boards are single-fiber unidirectional or single-fiber bidirectional

The ST2 board uses two wavelengths to transmit and receive signals. It works with the SFIU board for single-fiber bidirectional transmission of supervisory signals. The SFIU board converges the two wavelengths of the ST2 board at its LINE1 port for output. This applies to scenarios where IEEE 1588 clock signals need to be transmitted in supervisory signals.
