Abstract

An optical connection identification assembly includes first and second connectors for conveying optical signals within and away from the optical connection identification assembly, first and second optical filters configured for conveying optical signals to and from the respective first and second connectors and between each other, and first and second photodiodes. The first photodiode is configured for receiving optical signals from the first optical filter to confirm the optical connection identification assembly is receiving optical signals. The second photodiode is configured for receiving optical signals from the second optical filter to confirm the optical connection identification assembly is receiving optical signals. The first and the second connectors are on opposite sides of each of the first and the second optical filters and each of the first and the second photodiodes. Multiple optical connection identification assemblies are used in a system to prepare a connectivity map of a fiber optic system.
