Description

DESCRIPTION

FIBER OPTIC CASSETTES

Technical Field

This invention is related to fiber optic cassettes that are used in splice patching of fiber optic cables. These fiber optic communication cassettes form the Fiber Optic Distribution Modules (ODM) by being combined together and these modules form the Fiber Optic Distribution Frames (ODF) by being stacked in various numbers.

Prior Art

Using both side of the cassette and therefore for operational access its removal and music stand opening and its being fixed during the operation are not seen in the current applications.

While the miniflex tubes through which the fiber cables are passed enter the cassette with an appropriate angle, an integrated module that eliminates breaking possibility of the fiber cable by its novel design is not seen in the current applications.

With respect to correct distribution or error free and quick access to subscriber line, an embedded addressing system is not seen in known current applications. The removable design that provides ease of operation on the reel system on which the excess fiber cables that are hidden in cassette is wound and in this stage that allows easy helical storage of the fiber cable which is more prone to breaks when its shield is removed by assembling and disassembling the reel sidewall is not seen in current applications. Brief Description of the Invention

The object of this invention is to implement a fiber optic cassette system wherein the cassette can be completely removed via a slide, that can be opened and fixed like a music stand by its hinged and angled vertical design, that provides ease of use to the telecom operator during fiber optic patching, joining via an adaptor, hiding the excess parts, making changes on the cassette of which the both sides are operational on both ways and that allows combined use of both the splice and patching. Yet another object of this invention is to implement a fiber optic cassette system wherein an integrated module is not seen that eliminates possibility of loosening and breaking through its novel design by being self-fixed while entering to the cassette through miniflex tubes with an appropriate bend angle. Yet another object of the invention is to implement a fiber optic cassette system wherein cassette numbers and connection address range are placed on the cassette- front and connection number address labels are placed on the cassette covers and that contains which of the 1-24 local addresses in the cassette corresponds to which of the 2016 addresses in the frame.

Yet another object of the invention is to implement a fiber optic cassette system that facilitates operation in the reel system in which the excess fiber cables are hidden inside the cassette and that allows easy helical storage of 0.9 mm pigtails which are more prone to breaks by disassembly and assembly of the reel sidewalls.

The fiber optic cassette (3000) of the invention comprises a sliding hinge (3010) that allows the cassette to be completely taken outside and to erect at 105° angle in a music stand position.

The fiber optic cassette (3000) of the invention comprises a Miniflex tube (fiber cable guide, input tunnel) input and fixing module (3020) that enables fiber cable guides (miniflex tubes) to be implemented into the cassette with an appropriate bending angle.

The fiber optic cassette (3000) of the invention comprises a miniplex tube fixing cover (3022) that enables the fiber cable guiding tunnels (miniflex tube) to be fixed without use of a connector.

The fiber optic cassette (3000) of the invention comprises an addressing label (3030) which addresses in-cassette connections as well as the position of each joint in the frame at the first glance.

The fiber optic cassette (3000) of the invention comprises a fixing magnet (3040) that enables the cassette to stay in its first day form without coming loose due to multiple operations and resistance in cable harness.

The fiber optic cassette (3000) of the invention comprises a slide that enables the cassette to be completely taken outside.

The fiber optic cassette (3000) of the invention comprises a stand opening and stopping mechanism (3060) that enables cassette that has been taken outside to be erected at 105° angle and fixed.

The fiber optic cassette (3000) of the invention comprises at least one patch panel adaptor and organizer module (3080).

The fiber optic cassette (3000) of the invention comprises reel sidewall (3090) which provides easy access and operation to store excess fiber optic Pig-Tail cables inside the cassette as windings. The developed fiber optic cassette (3000); can be installed in 3U size 14 ODF Modules located inside the ODF-Optic Distribution Frame wherein each accommodates six cassettes. The fiber optic cassette (3000) comprises the sliding hinge system (3010), the miniflex tube connected fiber optic cable guide input module (3020) and addressing label system (3030) features of the invention.

An appropriate bending reel system on which the excess cables can be stored as a winding is placed inside the cassette and a removable reel sidewall is designed. As a precaution against loosening and fitting problems during multiple operations, a fixing magnet (3040) is placed at the end of the cassette.

An angled stopper is placed on the hinge (3010) design to enable the cassette system to be pulled opened and erected like a music stand.

In the case that the designed cover is mounted on the fiber optic cable guide input module (3020) on which the miniflex tube is fitted in order to direct towards fiber cable entrances and to guide, it fixes the miniflex tubes by compressing and the system eliminates the risk of breaking by always controlling the fiber cable stress and bending angle while the cassette is pulled in and out for operation or while opened and erected. The labeling system (3030) is located both on the cassette cover and on the cassette-front. When looked from front, the subscriber or the distribution place can be directly identified and on left side of the detailed label placed on the cassette that is pulled for operation the in-cassette-numbers 1-24 are defined and on the right side of the label the position inside the ODF is defined.

The miniflex tubes that will drive the fiber optic cable into the cassette are inserted through the input module (3020) and fixed by closing the module cover (3022). The recessed form on the cable input module is similarly applied on the cover and pins that enable it to self-lock itself are designed. The tracks on the input module ensure the fiber cable to be driven inside such that bending angle is preserved. This angle is maintained while passing to the other side of the cassette,

To allow the cassette to be completely taken out and erected (music stand opening) for easy and reliable operation, the hinge (3010) is designed such that it can enter the slide. When the rod housing is erected on the angled stopper - slide part of the hinge (music stand opening), the stopper and its correspondence on the hinge cassette part are designed. The magnet mechanism (3040) is added on the angled stopper part of the hinge which ensures that cassette remains in the rack in its exact position. The installation housing in which the magnet and its housing enters is considered.

The fiber optic cassette (3020) is designed such that the winding reel (3090) is removably designed to wind and store the excess cables after the operation. By pressing the suitable tab on the cassette body with a finger and inserting this reel, the cable windings are protected. A sleeve holder is placed on the other side of the cassette to perform splice operations. The part that serves as the patch panel (3080) of the cassette is designed such that suitable adaptors can be fitted. The cable organizer is present as an extension of this part. The patch panel adaptor part (3080) is mounted to the body via left and right legs.

When looked to the ODF-Fiber optic distribution frame from front, the cassette- fronts installed to the Fiber optic distribution modules can be directly seen and a front label on which the sequence number of the cassette in the frame is defined is placed on the cassette-front (3000). On the right side of each front label, the connection range of the cassette is given with the starting and ending numbers. A cover label is placed to number and address all the connections when the cassette is pulled out. This label is designed such that it has a left region in which the 24 connections are numbered and a right region in which the sequence of all the connections in the ODF-fiber optic connection frame is defined, so it ensures error free and easy operational access.
