Abstract

Method and apparatus for feeding on optical waveguide through a partition device, such as a wellhead outlet are disclosed. For some embodiments, the wellhead outlet includes a first chamber having a first port, a second chamber having a second port connected by a path to the first port for feeding an optical waveguide through to the first chamber, and a strain relief member coupled with the first chamber to limit motion of the optical waveguide at or near the first port. The strain relief member can be a rigid curved tube coupled to the first port and/or a fiber management member providing one or more fiber retention pathways.
