Two PD1 boards and one DMS board work together to provide TPS protection.

• True
• False

In the colorless scenario, two same wavelengths can be multiplexed on the same multiplexer board without affecting each other.

• True
• False

Which of the following statements about the EX40 board is false?

• The board is an enhanced 40-channel multiplexer/demultiplexer board.
• The board supports online optical power monitoring.
• The board can be used in a single-fiber bidirectional transmission system.

• The board can be used in a two-fiber bidirectional transmission system.

The optical spectrum analysis board is a key board for routine maintenance of WDM devices. Which of the following indicators of optical signals can be detected online by connecting the MON port of the optical-layer board?

• Insertion loss

• Optical power

• Center wavelength

• OSNR

Which of the following are optical-layer boards?
