Coupler mounting kits are provided in two options:
•
Symmetric coupler mounting kits
: This option splits the power evenly between the
two ODUs. A nominal 3 dB is lost in each arm of the coupler.
•
Asymmetric coupler mounting kits
: This option splits the power in a way which
favours one ODU. A nominal 1 dB is lost in the Main arm of the coupler with a nominal
7 dB being lost in the other arm. This is often a preferred option for 1+1 Hot Standby
links (see
Couplers increase system loss.
The choice of coupler mounting kit depends on the frequency variant and on the coupler
type required (symmetric or asymmetric).
