  • Container for accommodating optical fiber coil and optical fiber module having the container
    Patent number: 7548679
    Abstract: A container for an optical fiber coil and an optical fiber module including the container is provided, wherein an excess length portion of a pigtail fiber is accommodated in the container and the remaining portion can be drawn out from the container. The container includes a first part for accommodating a coil having a functional optical fiber, and a second part disposed on an outer periphery side of the first part and windingly accommodating a pigtail fiber that is optically connected to the functional optical fiber. The second part has a gap that extends over the entirety of the outer periphery, and communicates with the exterior. The optical fiber module includes the container, the coil having the functional optical fiber accommodated in the first part of the container, and the pigtail fiber that is optically connected to the functional fiber and that has a portion windingly accommodated in the second part.
