Abstract
An optical fiber directional coupler housing having a primary protective body substantially formed as a rectangular block with a receiving space therein. A slot in the primary protective body provides the receiving space therein. The coupled portion of the coupler to be housed is positioned in the receiving space. A resilient support material having an index of refraction less than that of the coupled portion extends into the receiving space extending between the coupled portion of the coupler which it also at least partially surrounds and the primary protective body. Plugs are typically provided at the ends of the protective body to secure the optical fibers extending from the coupled portion to the body. A heat shrinkable tubing is used as a jacket which encompasses and extends beyond the primary body.
