The present disclosure relates to optical organizers and particularly removable optical organizers, which are used in closures for telecommunications industry.
Telecommunication cables are used for distributing data across vast networks. Modern communication and data networks rely on fiber optic transmission lines or cables due to their high speed and low attenuation characteristics. As these fiber optic cables are routed across networks, it is necessary to periodically open the cable and splice or tap into the cable so that data may be distributed to “branches” of the network. The branches may be further distributed until the network reaches individual homes, businesses, offices, and so on. The distributed lines are often referred to as drop lines.
At each fiber access point where the cable is opened, it is necessary to provide some type of closure to protect the cable (and potentially unjacketed fiber) and allow easy and repeated access to the cable. These closures need to provide features to store the fiber optic lines as well as allow for the interconnection between the incoming and outgoing fiber optic lines.
The purpose and configuration of the closure will vary depending on where the closure is located in a network. When a closure is used to interconnect distribution lines, the number of splices that can be made in the closure is a factor in determining which closure and which accessories within the closure are used. Frequently, telecommunication carriers want to use the smallest closure that can accommodate the needed number of splices due to factors like the cost of the enclosure, cost of installation, as well as aesthetics for above grade installations. At another point in the network a closure can be used to distribute signals from a few optical fibers to many optical fibers through the use of optical splitters. While in another application, a closure may also contain a termination field for interconnecting optical fiber connectors.
As networks expand, telecommunication carriers may want to add a cable to an existing fiber access point to increase capacity of a portion of the network or bring service to an area which did not have high speed, gigabit service previously. In order to do this the optical fiber interconnection capacity of closures at these fiber access points needs to increase.
Organizers are a primary component used within closures to house optical fiber interconnection components such as optical fiber splices, optical splitters, cassettes, splicing trays, splitter trays, WDM trays, etc. Moreover, due to the expected and continued growth in the volume of data transmitted over fiber optic networks, the need for improved optical organizers has grown considerably. Fiber optic cables having higher fiber counts are now more common, and often more time and effort is required to route, store, and splice optical fibers. Thus, there are various needs for improved organizers, and particularly optical organizers that are removable and which can support the breadth of optical fiber interconnection and capacity expansion.
The present disclosure relates to optical organizers and particularly to optical organizers are removable from a closure without disassembly of the closure. The organizer is configured to receive several cassettes, splicing trays, splitter trays, WDM trays, for the connection of the optical fibers.
According to one aspect, an optical organizer includes a base with a support opening; at least one support positioned under the optical organizer, the at least one support comprising a support positioning element positionable within the support opening such that the support opening complements the support positioning element, and a passage between the at least one optical organizer and the at least one support for positioning of an adhesive element.
According to another aspect, an closure-optical organizer assembly include a closure body and an optical organizer assembly, including at least one optical organizer having a base with a support opening; at least one support positioned under the optical organizer, the at least one support comprising a support positioning element positionable within the support opening such that the support opening complements the support positioning element, and a passage between the at least one optical organizer and the at least one support for positioning of an adhesive element.
Additional aspects, features and advantages will be set forth in the detailed description which follows, and in part will be readily apparent to those skilled in the art from that description or recognized by practicing the embodiments as described herein, including the detailed description which follows, the claims, as well as the appended drawings.
It is to be understood that both the foregoing general description and the following detailed description are merely exemplary, and are intended to provide an overview or framework to understanding the nature and character of the claims. The accompanying drawings are included to provide a further understanding, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments, and together with the description serve to explain principles and operation of the various embodiments.
The present disclosure will be further described with reference to the accompanying drawings:
The figures are not necessarily to scale. Like numbers used in the figures may be used to refer to like components. However, it will be understood that the use of a number to refer to a component in a given figure is not intended to limit the component in another figure labeled with the same number.
Various exemplary embodiments of the disclosure will now be described with particular reference to the Drawings. Exemplary embodiments of the present disclosure may take on various modifications and alterations without departing from the spirit and scope of the disclosure. Accordingly, it is to be understood that the embodiments of the present disclosure are not limited to the following described exemplary embodiments, but are to be controlled by the limitations set forth in the claims.
In the following description, reference is made to the accompanying drawings that form a part hereof and in which are shown by way of illustration. It is to be understood that other embodiments are contemplated and may be made without departing from the scope or spirit of the present disclosure. The following detailed description, therefore, is not to be taken in a limiting sense.
Spatially related terms, including but not limited to, “lower,” “upper,” “beneath,” “below,” “above,” and “on top,” if used herein, are utilized for ease of description to describe spatial relationships of an element(s) to another. Such spatially related terms encompass different orientations of the device in use or operation in addition to the particular orientations depicted in the figures and described herein. For example, if an object depicted in the figures is turned over or flipped over, portions previously described as below or beneath other elements would then be above those other elements.
As used herein, when an element, component or layer for example is described as forming a “coincident interface” with, or being “on” “coupled with” or “in contact with” another element, component or layer, it can be directly on, directly coupled with, in direct contact with, or intervening elements, components or layers may be on, connected, coupled or in contact with the particular element, component or layer, for example. When an element, component or layer for example is referred to as being “directly on,” “directly coupled with,” or “directly in contact with” another element, there are no intervening elements, components or layers for example.
The organizer described herein is a configurable tray that can be used to interconnect optical fibers, as used in various types of fiber optic cables. The optical fibers, however, could be in the form of individual 250 μm coated optical fibers, 900 μm buffer coated optical fibers, small diameter jacketed cables, optical fibers contained in buffer tubes, or optical ribbon fibers.
The organizer is configured to subdivide fiber, allowing for better organization and increased density of both stored and fiber optic splicing. Better organization, in turn, contributes to improved efficiencies, particularly during installation.
