1+1 Fd Configuration; Configuration Requirements - Huawei OptiX RTN 600 Product Description

Note:
The 1+1 HSB switching can also be triggered when the local NE receives the RDI
signal coming from the remote NE.

4.4 1+1 FD Configuration

1+1 frequency diversity (FD) is one of the methods used for channel backup. The
OptiX RTN 600, configured with 1+1 FD, uses two channels that have certain
frequency spacing to transmit and receive the same signal, and one-channel signal is
selected. In this way, the fading in the signal transmission is reduced.
In a 1+1 FD system, the frequency correlation of two channels is required to be small
enough to avoid simultaneous severe fading occurring to the receive signals of the
two diversities, thus ensuring a better quality of frequency diversity.
The 1+1 FD switching does not affect services.
