1. Field of the Disclosure
The technology of the disclosure relates to fiber optic panels having fiber optic components for establishing fiber optic connections.
2. Technical Background
Benefits of optical fiber use include extremely wide bandwidth and low noise operation. Because of these advantages, optical fiber is increasingly being used for a variety of applications, including but not limited to broadband voice, video, and data transmission. Fiber optic networks employing optical fibers are being developed and used to deliver voice, video, and data transmissions to subscribers over both private and public networks. These fiber optic networks often include separated connection points at which it is necessary to link optical fibers in order to provide “live fiber” from one connection point to another connection point. In this regard, fiber optic equipment is located in data distribution centers or central offices to support interconnections.
The fiber optic equipment is customized based on the application need, and is typically included in housings that are mounted in equipment racks to maximize space. One example of such fiber optic equipment is a fiber optic panel. A fiber optic panel is designed to provide cable-to-cable fiber optic connections. The fiber optic panel is typically mounted to a chassis mounted inside an equipment rack or housing. Fiber optic adapters are disposed through openings on a front of the panel and accessible to receive fiber optic connectors from connectorized fiber optic cables to establish fiber optic connections. Due to increasing bandwidth needs and the need to provide higher connectivity density in data centers, it may be desired to provide panels having a high adapter count. However, one factor that influences the number of adapters included is the amount of surface area on the front of the panel. Further, another factor is the number of adapters included in a fiber optic panel providing sufficient finger access to connect connectors to the adapters. In this regard, the openings in the fiber optic panel are spaced to provide sufficient finger access between adapters thus limiting the density of adapters that can be included in the panel. The density of adapters and panels is also influenced by the fiber's minimum bend radius.
Embodiments disclosed in the detailed description include fiber optic panels and related apparatuses configured to retain fiber optic components for establishing fiber optic connections. The fiber optic panels are configured such that the fiber optic components and any fiber optic connections made to the fiber optic components can be retained along a depth axis in a depth space of a chassis when the fiber optic panel is inserted into the chassis. The fiber optic components are oriented in the fiber optic panel such that the longitudinal axes of the fiber optic components are not parallel to the depth axis of the chassis. In this manner, the area of the depth space of the chassis is utilized to retain fiber optic components so that a greater density of fiber optic components can be supported by fiber optic panels for a given length of the chassis. The fiber optic panel may be any type of fiber optic patch panel or fiber optic module. The fiber optic components retained by the fiber optic panels may be any type of fiber optic component, including but not limited to fiber optic adapters and connectors.
In one embodiment, a chassis is provided having a first end and a second end aligned along a depth axis of the chassis and having a depth space therebetween. The depth axis is provided along a Z-axis of the chassis. A fiber optic panel in the form of a fiber optic patch panel is provided. The fiber optic patch panel is configured to be inserted into the chassis between the first end and the second end along the depth axis of the chassis. The fiber optic patch panel is configured to retain a plurality of fiber optic components in the depth space between the first end and the second of the chassis. The plurality of fiber optic components are oriented in the fiber optic patch panel such that the longitudinal axes of the fiber optic components are not parallel to the depth axis. When it is desired to access the fiber optic components retained by the fiber optic patch panel, the fiber optic patch panel can be moved out or extended from the chassis to gain access to the fiber optic components. The fiber optic patch panel can be moved back or retracted into the chassis for storage when access is completed such that the fiber optic components and fiber optic connections made to the fiber optic components are retained in the depth space of the chassis.
Embodiments disclosed herein also include a fiber optic panel used to support and retain fiber optic components in a depth space of a chassis comprised of a planar member. The planar member is disposed in a plane between a first end and a second end of the planar member such that fiber optic components retained in the fiber optic panel are retained in a depth axis in a depth space of a chassis when the fiber optic panel is installed in the chassis. The plurality of fiber optic components are retained in a plurality of openings disposed in a planar surface of the planar member. The plurality of openings may be oriented orthogonally or substantially orthogonally to the plane of the planar member.
Embodiments disclosed herein also include a fiber optic panel chassis comprising an enclosure and having an opening disposed therein along a depth axis of the chassis between a first end and a second end of the chassis. At least one first channel is disposed in an inner surface of a first side of the enclosure along the depth axis of the chassis. At least one second channel is disposed in an inner surface of a second side of the enclosure along the depth axis opposite the first side such that the channels are aligned. The enclosure of the chassis is configured to receive a fiber optic panel in the depth axis inserted in the at least one first channel and the at least one second channel of the enclosure. Additional channels can be arranged on inner surfaces of the enclosure adjacent to the inner surfaces of the first and second sides of the enclosure.
Additional features and advantages of the embodiments 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 that 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 present embodiments, and are intended to provide an overview or framework for understanding the nature and character of the embodiments. The accompanying drawings are included to provide a further understanding of the embodiments, and are incorporated into and constitute a part of this specification. The drawings illustrate various embodiments, and together with the description serve to explain the principles and operation of the embodiments.
Reference will now be made in detail to the embodiments, examples of which are illustrated in the accompanying drawings, in which some, but not all embodiments are shown. Indeed, the embodiments may be embodied in many different forms and should not be construed as limiting herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Whenever possible, like reference numbers will be used to refer to like components or parts.
Embodiments disclosed in the detailed description include fiber optic panels and related apparatuses configured to retain fiber optic components for establishing fiber optic connections. The fiber optic panels are configured such that the fiber optic components and any fiber optic connections made to the fiber optic components can be retained along a depth axis in a depth space of a chassis when the fiber optic panel is inserted into the chassis. The fiber optic components are oriented in the fiber optic panel such that the longitudinal axes of the fiber optic components are not parallel to the depth axis of the chassis. In this manner, the area of the depth space of the chassis is utilized to retain fiber optic components so that a greater density of fiber optic components can be supported by fiber optic panels for a given length of the chassis. The fiber optic panel may be any type of fiber optic patch panel or fiber optic module. The fiber optic components retained by the fiber optic panels may be any type of fiber optic component, including but not limited to fiber optic adapters and connectors.
In this regard,
By example without limitation, the fiber optic components 14 may be disposed in the fiber optic patch panel 10 such that a density of up to or at least two hundred sixteen (216) fiber optic connections can be supported per “U” unit size of the chassis 12 (e.g., 1 U may be equal or approximately equal to seventeen (17) inches in width (i.e., X-axis) by 1.75 inches in height (i.e., Y-axis)). The density is dependent on the number of fiber optic components 14 disposed in the fiber optic patch panel 10 and the number of fiber optic connections supported by each fiber optic component 14. For example, a multi-fiber fiber optic component 14 may support two, four, eight or twelve fiber optic connections. Regardless of the particular size of the chassis 12, a greater density of fiber optic connections is possible due to the fiber optic patch panel 10 supporting fiber optic components 14 in the depth space DS of the chassis 12, and as a result, a greater density of fiber optic connections per unit size of width of the chassis 12.
As illustrated in
As illustrated in
Because the fiber optic patch panel 10 is moveable, it may also be desired to provide for the fiber optic cables 44 to contain slack to allow for extending the fiber optic patch panel 10 out from the chassis 12. Otherwise, movement of the fiber optic patch panel 10 out from the chassis 12 may risk disconnecting the fiber optic cable 44 from the fiber optic components 14. In this regard, a slack management device may be employed to store any slack in the fiber optic cable 44 after fiber optic connections have been established with fiber optic components 14. Thus, when the fiber optic patch panel 10 is extended from the chassis 12, the slack in the fiber optic cable 44 allows the fiber optic connection established with the fiber optic cable 44 to be retained without interruption. In this regard, a fiber optic guide panel 50 can be provided as illustrated schematically in
The retention members 52 may be disposed on both sides of the fiber optic guide panel 50 so that retention members 52 are located adjacent fiber optic components 14 from two adjacent fiber optic patch panels 10 installed in the chassis 12 as illustrated in
In this embodiment, the retention member 52 is provided in a loop configuration, but any other design or geometry is possible. The retention member 52 could include a spool or other type of retracting mechanism to allow for retraction of slack in a fiber optic cable 44 connected to a fiber optic patch panel 10 when the fiber optic patch panel 10 is retracted into the chassis 12. Also like the fiber optic patch panel 10, the fiber optic guide panel 50 can be designed to be moved about the chassis 12 so that the fiber optic cables 44 retained by the retention member 52 can be moved along with the fiber optic patch panel 10 when establishing and/or modifying fiber optic connections if desired. The fiber optic guide panels 50 include rails 54A, 54B (
Further, in order to prevent or assist in the prevention of bending or kinking of the fiber optic cable 44 beyond a minimum desired bend radius, the retention member 52 can also be designed to provide a bend radius R. The retention member 52 can be designed to include one or more bend radii R as illustrated in
To further illustrate how the fiber optic patch panels 10 and fiber optic guide panels 50 of
