Abstract
A cassette for optical fibers includes a bottom surrounded by discontinuous rim segments between which access channels for the fibers are delimited. Each of the access channels is delimited over a substantially identical width on the bottom by two facing sidewalls. A block projects from the bottom of the cassette and has two side faces facing end portions of corresponding adjacent rim segments at respective corners, thereby forming similar double access channels at the corners. An element of the first type or second type sized to the double access channels is selectively positioned within the double access channels. The element of the first type is constituted by a flexible slab having spaced parallel slots receiving and retaining bare fibers. A channel element of the second type is constituted by a rigid, U-shaped channel section part having two flanges interconnected by a web, with each flange including a series of teeth. The teeth delimit slots receiving and retaining protected fibers.
