QUESTION: 116

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

QUESTION: 117

What are the possible reasons for the failure of route calculation by the optical layer path (OCh level)?

The optical fiber is connected incorrectly. The wavelength of the WDM side port of the OTU board is inconsistent with the wavelength of the optical crossover.
Network layer OTS path is missing
The fiber attenuation between the TDC and RDC ports of the OAU board is too large
