Attaching ODUs to coupler
To attach the ODUs to the coupler and mount the assembly on the pole, proceed as
follows:
1
Remove protective film from the coupler ports.
2
Apply silicone grease to the ‘O’ rings of the coupler transitions.
3
Fit the ODUs to the coupler transitions, ensuring that the waveguide interfaces
align correctly for vertical or horizontal polarization. Fit both ODUs such that
handles are at the top and connectors at the bottom. For asymmetric couplers,
check that the ‘MAIN’ and ‘STANDBY’ sides of the coupler can still be identified.
