Question # 20

When configuring LMSP, there are two switching modes: single turbulent cutting and inserting and double full switching. Single-ended switching does not require self-use protection

True

False

Question # 21

During the normal operation of the network, the service channel protected by ODUK SNCP generates a condition for triggering protection switching, and the service has been automatically switched to the protection channel. When the fault

of the working channel is eliminated, the service cannot be automatically restored to the working channel.

The SNCP service type is inconsistent with the service scenario requirements

Protection group 'Recovery Mode' is 'Non-Recovery'

A small number of bit errors occur in the working channel

Manual switching, locking switching or forced switching commands are implemented artificially

When the working channel is normal, the business needs to delay the "waiting for recovery time" and then switch from the protection channel to the working

channel.

Question # 23

Regarding the comparison of Raman amplifiers with EDFAs, which of the following statements is false?

The Raman amplifier selects different pump sources to amplify signals in different bands, so the Raman amplifier has no gain bandwidth limit in theory, while the EDFA has a range of gain bandwidth

The gain calculation/testing method of Raman amplifier and EDFA is consistent, both are "gain = output power - input power

The gain medium of Raman amplifier is transmission fiber; the gain medium of EDFA is EDF (Erbium Doped Fiber)

The equivalent noise figure of a Raman amplifier is smaller than that of an

EDFA
