The present invention relates to fiber bundles and methods for making fiber bundles. According to one embodiment of the invention, a fused fiber bundle has a terminal section ending with an endface, and includes a plurality of optical fibers, each of the optical fibers having a terminal segment ending with a proximal end, and a distal end; and a cellular holding structure, the cellular holding structure including a cellular web portion having a plurality of longitudinal cells arranged substantially in parallel and surrounded by a web material; and a tube portion surrounding the cellular web portion. The terminal segments of the optical fibers are arranged substantially in parallel, and the terminal segment of each optical fiber is disposed in a longitudinal cell of the cellular holding structure and substantially fused to the web material, thereby forming the terminal section of the fused fiber bundle.
