OLP can only be configured on the FIU line side of each site

Single-ended switching optical line protection requires APS protocol

Segmentation protects the combined optical signal, and separate routing is used between sites

The OLP board is used to protect the line fiber

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
