Abstract: A fiber optic cassette includes a body defining a front and an opposite rear. A cable entry location, such as a multi-fiber connector, is defined on the body for a cable to enter the cassette, wherein a plurality of optical fibers from the cable extend into the cassette and form terminations at one or more single or multi-fiber connectors adjacent the front of the body. A flexible substrate is positioned between the cable entry location and the connectors adjacent the front of the body, the flexible substrate rigidly supporting the plurality of optical fibers. Each of the connectors adjacent the front of the body includes a ferrule. Dark fibers can be provided if not all fiber locations are used in the multi-fiber connectors. Multiple flexible substrates can be used with one or more multi-fiber connectors.

Abstract: A fiber optic cassette includes a body defining a front and an opposite rear. A cable entry location is defined on the body for a cable to enter the cassette, wherein a plurality of optical fibers from the cable extend into the cassette and form terminations at non-conventional connectors adjacent the front of the body. A flexible substrate is positioned between the cable entry location and the non-conventional connectors adjacent the front of the body, the flexible substrate rigidly supporting the plurality of optical fibers. Each of the non-conventional connectors adjacent the front of the body includes a ferrule, a ferrule hub supporting the ferrule, and a split sleeve surrounding the ferrule.

Abstract: The present disclosure relates generally to methods for processing ferrules of fiber optic connectors such that the amount of polishing that is required is eliminated or at least reduced. In one example, an energy source is used to remove excess adhesive from the end face of the fiber and likely from an end face of the ferrule.

Abstract: An apparatus and a method for maintaining a file system is described. A method may include receiving a request for allocating a first block of a file system to a file, the first block comprising a first data from the file. The method also includes computing a first hash value by hashing the first data with a first hashing procedure and computing a second hash value by hashing the first data with a second hashing procedure. The method also includes using the first and the second hash values to determine whether a tree structure among a plurality of tree structures has a matching hash value among a plurality of hash values. Each of the plurality of hash values in the tree structure correspond to a block among a plurality of blocks stored in the file system. The method further includes in response to determining that the tree structure has the matching hash value, allocating the corresponding block to the file and updating a reference count of the corresponding block in the tree structure.
