Wavelength regeneration in a network

A system for optimizing a telecommunications network, the system comprising:

• at least one processor;
• and
• memory, operatively connected to the at least one processor and containing instructions that, when executed by the at least one processor, cause the system to:
• access information describing fiber segments in the telecommunications network;
• identify, based on the information, a plurality of spans of the fiber segments in the telecommunications network that can be traversed by a wave without intermediate regeneration;
• generate an optimal placement for at least one regeneration device in the telecommunications network based on at least:
• a constraint requiring that, for at least a particular span of the identified spans, the particular span does not exceed a maximum number of intermediate nodes that are interconnected without intermediate regeneration;
• and
• cause display of the optimal placement for the at least one regeneration device in a graphical user interface.

A method for determining an optimal placement for a regeneration device in a telecommunications network, comprising:

• identifying a set of possible spans of the telecommunications network, wherein each possible span of the set of possible spans:
• can be traversed by a wave without intermediate regeneration;
• and
• comprises a plurality of nodes that are interconnected by one or more fiber segments of the telecommunications network;
• determining, based on the set of possible spans, an optimal placement for a regeneration device in the telecommunications network according to a constraint requiring that, for at least a particular span of the set of possible spans, the particular span does not exceed a maximum number of intermediate nodes that are interconnected without intermediate regeneration;
• and
• generating a user interface comprising a display of the optimal placement for the regeneration device in a graphical user interface.
