31.5Maximum cable length

The maximum length of all optical fibers together (both POF and GOF) in the system depends on the number of nodes in the system. Each piece of equipment has been assigned a number of nodes.

The graph (see figure 31.5) shows the relation between the number of nodes in the system and maximum optical fiber length in the system.

Note

A system may not contain more than 63 nodes.

Note

The PRS-FINNA counts as 0 nodes for the system limit of 63 nodes, but as 1 node for the maximum optical fiber length. Therefore, the dashed part of the line is only applicable to systems with PRS-FINNA Fiber Interfaces.
