Abstract

An optical fiber holding device may comprise a first track and a second track. The first track may be configured to hold and guide a first optical fiber from a first track input location to a first track output location, wherein the first track is configured to allow the first optical fiber to connect to a first optical component and a first optical communication point. The second track may be configured to hold and guide a second optical fiber from a second track input location to a second track output location, wherein the second track is configured to allow the second optical fiber to connect to a second optical component and a second optical communication point.
