1+0, 1+1, 2+0 Deployments,,,,,

#Microwave_ODUs can be deployed in various configurations.

1.Microwave ODU in 1+0 Configuration with Antenna As picture#1.
The most common is 1+0 which has a single ODU, generally connected directly to the microwave antenna.
1+0 means “unprotected” in that there is no resilience or backup equipment or path.

2. Two Microwave ODUs in 1+1 HSB or 2+0 configuration with Coupler and Antenna as picture#2

For resilient networks there are several different configurations.  1+1 in “Hot Standby” is common and typically has a pair of ODUs (one active, one standby) connected via a Microwave Coupler to the antenna.
There is typically a 3dB or 6dB loss in the coupler which splits the power either equally or unequally between the main and standby path.

Other resilient configurations are 1+1 SD (Space Diversity, using separate antennas, one ODU on each) and 1+1 FD (Frequency Diversity)

3.The other non-resilient configuration is 2+0 which has two ODUs connected to a single antenna via a #coupler as in pictures #3.
The hardware configuration is identical to 1+1 FD, but the ODUs carry separate signals to increase the overall capacity.
