Question#1

The maximum dispersion tolerance of an OTU board is 800 ps/nm, then on the G.652 optical fiber, the dispersion-limited distance can be roughly considered as?

A. 40KM

B. 60KM

C. 80KM

D. 10KM

Question#2

Which of the following are the background reasons for introducing coherent communication? (Multiple choice)

A. Conventional 40G DQPSK PMD is only 6~8ps. After the rate is upgraded to 100G, the PMD tolerance is reduced by more than half, and it cannot support long-distance non-relay transmission.

B. For non-coherent signals with a data rate of 40G, it is necessary to add a TDC module at the receiving end, which has a slow response speed and does not support 1+1 protection scenarios, etc.

C. The biggest technical difficulty of coherence lies in high-performance FEC coding, and high-performance FEC coding will be available in 2011

D. When the baud rate is increased to 100Gbaud/s, the spectral width of the BPSK/DPSK pattern has exceeded 50GHz, and 50GHz interval transmission cannot be realized

If the OSN6800 device wants to achieve 1588V2 time synchronization, it must be equipped with an electrical cross-connect board

A. TRUE

B. FALSE

Question#4

A. Insertion loss

B. Bandwidth

C. Power Consumption

D. Crosstalk
