Chapter 5 Networking
5.1 Point-to-Point
In this networking mode, the services between two nodes are transported over
microwave.
In this case, the OptiX RTN 600 usually adopts 1+0 configuration. For key services,
1+1 configuration is also used.

5.2 Chain Networking
In this networking mode, all the microwave transmission nodes are connected in
series, but the head and tail nodes are not directly connected.
Figure 5-2 shows a chain network without protection for its microwave links. In this
example, the terminal nodes adopt 1+0 configuration, and the intermediate one
adopts 2+0 configuration.

Chain networking (without protection)
Figure 5-3 shows a chain network that offers protection to its microwave links. In this
example, the terminal nodes adopt 1+1 configuration, and the intermediate nodes
consist of two OptiX RTN 600 systems configured with 1+1 protection. The two
systems are connected through an E1 cable, STM-1o fiber, or STM-1e cable. This
mode can also be considered as the interconnecting of two point-to-point networks.
