Planning 1+0 links Chapter 2: Planning considerations

Planning 1+0 links
When planning 1+0 links, follow the process described in this section.
Concept of a 1+0 link
A 1+0 link is the simplest link to deploy. There is no redundant equipment deployed and so
costs are minimized. The 1+0 link provides no protection in the case of equipment failure.
If a link is very critical to network operation and where a service outage due to equipment
failure cannot be tolerated, consider deploying a 1+1 Hot Standby link.
Antenna, RFU and CMU configurations for 1+0
Select one of the following 1+0 link end configurations:
ODU with direct mount antenna (Figure 49).
ODU with remote mount antenna (Figure 50).
IRFU with remote mount antenna (Figure 51).
Do not install an ODU and an IRFU in the same link, as they cannot interwork.
