A service passes through two wavelength division rings. The two wavelength division rings are tangentially networked. The tangential network elements share the electronic rack. It is required to implement segmented ODURSKCP protection, that is, the protection is interrupted once for each fault in each ring. Which of the following types should be configured?
- A . SNC/N
- B . SNC/S or SNC/N
- C . SNC/S
- D . SNC/1
When using the wavelength division planning tool for wavelength division optical layer planning, a certain Och route passes through more than 12 spans, and the end-to-end optical red distance exceeds 1000km, resulting in OSNR not meeting the standard.
Which of the following optimization methods is correct?
- A . Use high-performance OTN circuit boards
- B . Raman amplifier is used at the receiving end of each span
- C . Select a station in the middle for electrical relay
- D . Each span uses high power optical amplifier
Which of the following statements is correct regarding the online optimization service adjustment of the AOSN network?
- A . Only supports manual optimization
- B . Optimization can change the protection level of the optimized LSP
- C . When optimizing the service path, the service will be interrupted, so it is necessary to apply for service optimization time.
- D . Only Diamond, gold, and silver levels support business optimization functions
The original path of the electrical layer ASON silver service and the two preset paths are as follows. When the optical fiber between site 2 and site 3 is disconnected, the service is switched to preset path 2 instead of preset path 1.
Which of the following is not a possible cause of this phenomenon?
- A . There are no available resources on the TE link from site 1 to site 5.
- B . The CPW_OMS_TEL_DEG alarm occurs on the TE link between site 5 and site 6.
- C . The priority of preset recovery path 2 is higher than the priority of preset recovery path 1.
- D . The TE link from site 1 to site 2 and the TE link from site 2 to site 6 belong to the same SRLG (Shared Risk Link Group).
After the GE service enters the client side of the Ethernet OTu board, it is encapsulated into an OTN signal or an SDH signal by the signal processing module. The processing of alarm signals encapsulated into OTN signals and SDH signals is the same.
- A . True
- B . False
When super 100G/100G and 10G are mixed and transmitted adjacently, the optical power of super 100G6/100G signals is recommended to be higher than the optical power of 10G signals, but cannot be higher than the single-wave nominal value of the optical amplifier board.
- A . True
- B . False
Full-duplex means that data can be sent and received simultaneously without interfering with each other.
- A . True
- B . False
What rigid pipes can MS-OTN equipment provide? (Multiple choice)
- A . LSP
- B . Wavelength
- C . ODUk
- D . PW
Which of the following is wrong about the cause of OA_LOW_GAIN alarm?
- A . The optical power input to the board is too high
- B . The insertion loss between the TDC and RDC optical ports is too large (only for OAU boards)
- C . The board that reported this alarm is faulty
- D . The gain of the optical amplifier board is set too low
After the OTN electrical layer ASON copper service is downgraded to a traditional unprotected service, it can be upgraded to a silver ASON service.
- A . True
- B . False
