PROTECTIVE CASING FOR OPTICAL FIBERS AND A FAN-OUT ASSEMBLY USING SAME

摘要

A robust protective casing is provided that includes an inner tubing having a passageway therethrough, an outer tubing, and a plurality of flexible strength members disposed between the inner and outer tubing. The protective casing has a wall tubing thickness ratio of the inner tubing wall thickness to the outer tubing wall thickness of about .05 or less while still inhibiting the kinking of the protective casing during relatively small bend radii. Additionally, an outer diameter of the protective casing is relatively small while still allowing the routing of a standard sized 900 micron tight-buffered optical fiber through the passageway. Thus, the protective casing is advantageous in applications where limited space is available space. A fan-out assembly using the protective casings is also described.
