Transmission distance

Dispersion coefficient

Emission wavelength

Fatigue of reception

NO.93 Which of the following technologies is the main difference between an open DWDM system and an integrated DWDM system?

Wavelength conversion techniques

Optical release technology

Multiplexing/multiplexing technique

Optical supervision technology

NO.94 The refractive index n1 of the fiber core must be the Q of the cladding refractive Mo n2, which is a necessary condition for transmitting the optical signal in the optical fiber.

is higher than

Below

Equal

NO.95 The rate of SF64 and SL64 boards is STM54. Therefore, the two plates can be interconnected.

True

False

NO.96 Which of the following bytes in the regenerator part overhead are associated with R-OOF and R-LOF? (Multiple Choices)

A2 ()

B1.

NO.97 Some SNCP protection inversion conditions are default, such as AU-AIS and TU-AIS. Other conditions are optional, such as HP-TIM and HP-SLM. Optional conditions can be flexibly set according to the level of the costume.

Error

NO.98 When performing fiber cut-off test on an ordinary MSP ring, which of the following alarms will be reported? (Multiple choice).

YOU-AIS

R-LOS

APSJNDl

NO.99 The 1510nm optical monitoring channel can be effectively amplified after passing through EDF

True

False

NO.100 QinQ technology can be used when multiple users need to share the same VCTRUNK and use the same VLAN ID.

True

Error

NO.101 On the NMS system, the network element performance monitoring time is set to () minutes and () hours.

NO.102 Which of the following statements about overhead bytes is incorrect?

A1 and A2 are framed bytes” These bytes are used to separate STM-1 frames in the signal stream. .

J0 is the regenerator part trace byte. This byte is used to resynch the send segment access point identifier so that the receiving end can verify its continuous connection to the specified sender.

B1 is better than holding interleaved parity 8 (BIP-8). This byte is used to monitor for bit errors in the regenerator section layer.

E1 and E2 are wired bytes. These bytes are used to provide a voice channel for order line connections.

NO.103 Which of the following is not the advantage of WDM?

Large capacity and transparent data transfer

Easy to upgrade and maximize protection for existing investments

gold replacement for SDH equipment

Future compatible with all optical switching networks

NO.104 The clock unit can only access the external clock source as the timing signal source of the system through the external clock interface. In addition; It can also output a processed clock and provide a clock source for other devices that need timing.

True

False

NO.105 Which of the following statements about the EFS4 board are correct? (Multiple choice).

The board has four FE ports. .

The board supports three layers of text exchange. .

The plate must be used with the processing plate.

The board interface is the LC interface.

Double-click the address

Multicast address

Broadcast address

NO.108 When the working PQ1 board is oversized, the device will perform and the TFS protection will be reversed. Which of the following statements about the switching process are correct? (Multiple choice).

cross-connect board checks the PQ1 board fault through the board status bus. .

If the protection PQ1 board is normal, the cross-connection board sends a switching message to the D75S corresponding to the faulty PQ1 board through the switching control bus. .

The D75S board responds to the switch message by transmitting the service to the shared protection bus and stopping sending the service to the tyrant PQ1 board

The protection PQ1 board receives and processes the services transmitted from the D75S board to the protection bus to complete the protection switching
