摘要： A bend limiter/strain reliever is provided for maintaining optical fiber bend limits at exit portals of a optic fiber closure for the closure's entire range of motion, from being fully closed to being fully open. Bend limits are maintained as optical fiber is directed on paths through a closure exit portal between the closure interior and wire brackets on the closure exterior. Fibers are retained, organized and strain relieved by the bend limiter/strain reliever such that directed fiber is maintain at a minimum bend radius on such fiber paths. The curved surface of the bend limiter/strain reliever allows the closure to be accessed without excessive bending of so routed optical fibers. In this manner, optical signal degradation and/or total loss is avoided by limiting the bending of routed optical fiber to radii in excess of a predetermined minimum bend radius. Horizontal members separate the bend limiter/strain reliever into compartments and make it easy to isolate fibers so that they may be efficiently traced and removed during system maintenance.
