The present invention relates generally to optical fiber cable management. More particularly, the present invention relates to a system for fixing and storing optical fiber cables in an optical fiber cable management system (for example, a management system that includes cable splicing).
Conventional systems often provide little or no splice tray identification, difficult access to optical fibers, and difficult or non-existent expansion of capacity.
It may be desirable to provide systems that organize and store optical fibers before and after the splicing of the optical fibers.
The present disclosure provides a modular splicing and optical fiber management system that can be used in a wide range of products such as, for example, splice closures, multiple dwelling unit (MDU) enclosures, cabinets, optical distribution frame (ODF) panels, and other applications that require splicing of optical fibers.

Various aspects of the system, as well as other embodiments, objects, features and advantages of this disclosure, will be apparent from the following detailed description of illustrative embodiments thereof, which is to be read in conjunction with the accompanying drawings.
Embodiments of the disclosure provide a modular and scalable platform for managing, storaging and splicing optical fibers. Embodiments provide a number of features which separately and together provide significantly better experience during optical fiber routing, optical fiber splicing, and subsequent management and maintenance of the system. Embodiments provide solutions to problems like splice tray identification, access to optical fibers, expanding the capacity of the system on demand, and other problems.
Embodiments include a cable fixation device in which a base portion and a side portion are structurally configured to be removably connected to another device to provide a modular and scalable cable management system that permits expandabilty on demand.
Embodiments include a fiber entry and storage device in which a base portion and a side portion are structurally configured to be removably connected to another device to provide a modular and scalable cable management system that permits expandabilty on demand.
Embodiments include a fiber management portion connecting device in which a first engaging portion, a second engaging portion, and a connection portion are structurally configured to connect a first fiber management portion to a second fiber management portion such that the first and second fiber management portions are movable as a unit so as to deter a user from contacting optical fibers located between the first and second fiber management portions.
Embodiments include a cable fixation plate the provides multiple points to which cables can be fixed, jackets of the cables can be removed, and fibers of the cables can be broken out so that the fibers can be directed to a fiber entry and storage plate.
Embodiments include a fiber entry and storage plate that provides features for initial fiber entry and guides the fibers from multiple cables to a splice tray mounting plate.
Embodiments include a connection system on the splice trays that provides fixing of the trays one to another, either, for example, two trays to each other, or in blocks, and that provides protection from accidental opening and mistakenly accessing an incorrect splice tray. Embodiments of the connection system provide additional tray identification using, for example, standard cable identification rings or clips.
In some installment locations, multiple systems 100 are mounted beside each other and/or on top of one another (with or without an intervening mounting plate) to increase density within a cabinet or other panel. For example, a side wall 530 of a first system 100 can be located adjacent to a side wall 520 of another system 100, and/or a base plate 510 of one system 100 can be mounted to an intervening mounting plate that is, in turn attached to a base plate 510 of another system 100.
As shown in
In this example, fiber entry and storage plate 400 has a plurality of fiber entry and retention portions such as, for example, fiber entry and retention areas 450 (shown in more detail in
One or more fiber storage portions such as, for example, fiber spools 420 are structurally configured to provide a place to wrap and store fibers that have entered fiber entry and storage plate 400 through fiber entry and retention areas 450 (and/or other areas). Side pathway portions such as, for example, side openings 465 provide a path for fibers and/or cables to pass from one fiber entry and storage plate 400 to an adjacent fiber entry and storage plate 400 located at its side. Fibers pass out of fiber entry and storage plate 400 at locations 467 and into one or more splice tray mounting plates 300 located above fiber entry and storage plate 400. A rear passage portion such as, for example, rear passage 468 is provided to allow fibers and/or cables to pass from front side 410 to rear side 430 of fiber entry and storage plate 400. A lower passage portion such as, for example, lower passage 469 is provided to allow fibers and/or cables to pass from front side 410 to rear side 430 of fiber entry and storage plate 400. Rear passage 468 and lower passage 469 provide paths for fibers and/or cables to pass between one fiber entry and storage plate 400 and another fiber entry and storage plate 400 mounted either in front of, or behind, it.
In this example, splice trays 200 have one or more gripping portions such as, for example, handles 230 that are structurally configured to extend from a front edge of splice tray 200. Tray lock 600 has an engaging portion such as, for example, a snap connector 610 that snaps onto, or otherwise engages or connects to, handle 230 of one splice tray 200, and an engaging portion such as, for example, a snap connector 611 that snaps onto, or otherwise engages or connects to, handle 230 of another splice tray 200. Snap connector 610 has a connection portion receiving portion such as, for example, a strap receiving member 620 that is structurally configured to receive an end portion such as, for example, an end 630 of a connection portion such as, for example, a strap 640 such that strap 640 is attached to snap connector 610. Snap connector 611 has a connection portion receiving portion such as, for example, a strap receiving member 621 that is configured to receive an end portion such as, for example, an end 635 of strap 640 such that strap 640 is attached to snap connector 611. In embodiments, one or both ends 630, 635 of strap 640 are structurally configured with hook and loop fasteners so that the length of strap 640 is adjustable. The adjustability of the length of strap 640 allows tray lock 600 to be adjusted to lock together different numbers of splice trays 200. For example, tray lock 600 is structurally configured to be shortened or lengthened from the length shown in
In embodiments, tray locks 600 and tray locks 700 have indicia that provide information as to the group of splice trays locked together. For example, in embodiments, tray lock 600 or 700 is a certain color to indicate a particular signal source and/or terminal location of the optical fiber. In embodiments, strap 640 includes a number of stripes or other markings of one or more colors and/or an alpha-numeric indicator. In embodiments, one or both of snap connectors 610, 611 includes a number of stripes or other markings of one or more colors and/or an alpha-numeric indicator. In embodiments, main body 720 and/or one or both of snap clips 710, 711 includes a number of stripes or other markings of one or more colors and/or an alpha-numeric indicator. Embodiments include other combinations of markings and/or colors and/or textures to differentiate one group of coupled splice trays from another group of coupled splice trays.
