A. The client-side interface at the local end receives normal light, and the client-side interface at the opposite end receives normal light

B. Abnormal light reception on the client side interface of the local end, abnormal light reception on the client side interface of the opposite end

C. The client-side interface of the local end receives normal light, but the client-side interface of the opposite end receives abnormal light.

D. The light reception of the client-side interface of the local end is abnormal, and the light reception of the client-side interface of the opposite end is normal.

A. The transmit optical power of the OTU board corresponding to this wave has decreased

B. Increased attenuation on the light path

C. The attenuation of the pigtail from the OTU board corresponding to this wave to the multiplexer increases

D. The gain slope of the amplifier changes

A. There is a local optical amplifier but no filter, the full-wave noise of the local optical amplifier affects the OSNR of the wavelength in the pass-through direction

B. The source and sink optical amplifiers of the optical crossover at this site must be in the same network element

C. If the local RMU is used to add waves and has an optical amplifier, the OSNR value of the wavelength in the pass-through direction detected by SOM will deviate from the actual value

A. FALSE

B. TRUE

A. After the session connection is established, the U2000 CORBA interface will periodically call back the ping method of the upper-layer network management registration object NMSSession_I (the ping here is the ping command usually referred to)

B. U2000 CORBA agent will actively send a heartbeat notification to OSS every 30s, its main purpose is to detect the service status of the notification service

C. The CORBA agent will continue to ping the Oss, and the connection will be disconnected if there is no response for 4 times

D. There is also a response timeout time between the OSS system and the notification service, which can be set by the customer according to the network situation
