Ring Network Topologies
Single-Fiber Ring
Scope
In the Single-Fiber Ring topology (example shown in
), up to 8 channels can be created
across the network. This means that up to 16 access-equipment units (e.g., LANs, PCs, etc.) can
be interconnected with this network topology – two per channel. Note that a channel can be
created between any two LDx00s.
Hardware
The hardware per LDx00 is as follows:
Basic Contents: 1 OADM Module and up to 4 Transponder Modules.
Options: 1 Management Module.
