The EDFA erbium-doped fiber amplifier is a key component of the new generation of optical fiber systems. Which of the following options are correct for the description of its advantages?
Standard Ethernet frame length should not be less than 64 bytes. Which of the following factors would cause this limitation?
Which of the following items can be included in the upgradeable boards of the PTN3900 NE upgrade operation?
Which of the following statements about the slave subrack SCC function is correct?
The characteristic of the open DWDM system is that there are no special requirements for the optical interface of the multiplexing terminal, and only these interfaces are required to comply with the optical interface standard
recommended by ITU-T. The DWDM system adopts wavelength conversion technology to convert the optical signal of the multiplexed terminal into a specific wavelength, and the optical signal of different terminal equipment is converted into
different wavelengths that comply with ITU-T recommendations, and then multiplexed.
