Abstract
An optical fiber closure includes a housing having opposing walls, each of the opposing walls having an aperture defined therein. Each aperture is adapted to receive an optical fiber therethrough. A bend limiter is proximate each aperture. Each bend limiter includes a proximate edge, a distal edge, and an arcuate surface. The arcuate surface extends between the proximate and distal edges and has a radius of curvature greater than a predetermined minimum bend radius. The distal edge of each bend limiter is substantially aligned with an outer edge of a respective one of the opposing walls of the optical fiber closure.
Claims10
An optical fiber closure, comprising:
- a housing having opposing walls, each of the opposing walls having an aperture defined therein and adapted to receive an optical fiber therethrough;
- and
- a bend limiter proximate each aperture, each bend limiter including a proximate edge, a distal edge, and an arcuate surface, the arcuate surface extending between the proximate and distal edges and having a radius of curvature greater than a predetermined minimum bend radius;
- wherein the distal edge of each bend limiter is substantially aligned with an outer edge of a respective one of the opposing walls.
An optical fiber closure, comprising:
- a housing having opposing walls, each of the opposing walls having respective aligned apertures defined therein and adapted to receive an optical fiber therethrough, and each of the opposing walls having opposing channels extending along a portion of the length thereof,
- at least one optical fiber trough supported within opposing channels in a respective one of the opposing walls;
- and
- a bend limiter proximate each aperture, each bend limiter including a proximate edge, a distal edge, and arcuate surface, the arcuate surface extending between the proximate and distal edges and having a radius of curvature greater than a predetermined minimum bend radius;
- wherein the distal edge of each bend limiter is substantially aligned with an inner portion of an optical fiber trough when such optical fiber trough is supported in the opposing channels of a respective one of the opposing walls.
An optical fiber trough, comprising:
- a base member having an inner edge and an outer edge;
- an inner member extending from outward from the inner edge, the inner member having opposing edges and a groove formed in each of the opposing edges;
- an outer member extending outward from the outer edge, the outer member having a flat surface opposing an arcuate surface;
- and
- a central member extending outward from the base member and disposed between the first and second side members, the central member having opposing flat surfaces and opposing arcuate surfaces;
- wherein the arcuate surface of the outer member and the opposing arcuate surfaces of the central member each have a radius of curvature greater than a predetermined minimum bend radius.
