1. A system comprising:
a network interface arranged in communication with a network for obtaining data associated with performance of a plurality of inter-node fibers and intra-node fibers and associated fiber connections;
an interactive user interface;
a processing device; and
a memory device configured to store computer logic having instructions that, when executed enable the processing device to
log the data obtained via the network interface over time in the memory device as historical data,
analyze health of the plurality of inter-node fibers and the intra-node fibers and the associated fiber connections, based on at least optical power measurements and Optical Time-Domain Reflectometry (OTDR) measurements from the historical data and immediate data newly obtained by the network interface, wherein analyzing the health of the fiber connections includes detecting one or more issues of the fiber connections and classifying the one or more issues as one of instantaneous issues and long-term issues,
display a report on the interactive user interface, the report configured to show the health of the plurality of inter-node fibers and the intra-node fibers and the associated fiber connections, and
cause one or more of maintenance and routing changes in the network based on the health.
