DETAILED DESCRIPTION

[0015] FIG. 1 shows an expanded view of one embodiment of an in-line sealed adapter tube 100. The adapter tube 100 includes an adapter body 102, a first end 104 and a second end 106 opposite the first end. The first end 104 is configured to couple to a first adapter endcap 108. The second end 106 is configured to couple to a second adapter endcap 110. Each of the first end 104 and the second end 106 is configured to snap fit a respective adapter endcap. For example, as shown by the dotted circle 112, the second end 106 includes a tab configured to engage an opening on the second adapter endcap 110. In some embodiments, the adapter body 102 may be symmetrical so that the adapter endcaps may go on either end. In various embodiments, the adapter body 102 may comprise a single housing.

[0016] The in-line sealed adapter tube 100 further includes a first seal 114 disposed at the first end 104, and includes a second seal 116 disposed at the second end 106. For example, each of the first seal 114 and the second seal 116 may be an O-ring. Each of the first end 104 and the second end 106 may further include slots 118 configured to receive cable ties for secondary retention. In various embodiments, the adapter body and the adapter endcaps may be custom molded parts.

[0017] FIG. 2 further shows the adapter tube 100 being configured to receive connectors. The first adapter endcap 108 is configured to receive a hardened connector 200. For example, the hardened connector 200 may be an OptiTap connector, or any other harsh environment or outdoor connector. The hardened connector 200 is coupled to an adapter 202. The adapter tube 100 may further be configured to receive a hardened connector nut 204, such as an OptiTap nut. Further, the second adapter endcap 110 may be configured to receive a fitting, such as an NPT fitting. In one example, the adapter endcap 110 may be sized for 0.5 inch NPT fitting. The second adapter endcap 110 may be configured to receive a fitting, such as a Sealcon fitting 206, and a nut 208, such as a Sealcon nut. Thus, one end of the adapter tube may be configured to couple to a hardened connector, whereas the other end may be configured to receive a non-hardened connector, such as an industry standard connector or Clearfield's Fieldshield pushable connector. The non-hardened connector is thus protected within the adapter body 102 and sealed off from the environment.

[0018] FIG. 3 shows a partially assembled view of the in-line adapter tube 100. As shown, the second end 106 is configured to receive an optical fiber cable 300 coupled to a non-hardened connector 302. The non-hardened connector may be an industry standard connector or Clearfield's Fieldshield pushable connector. As the non-hardened connector 302 is coupled to the adapter 202, it is pushed through the adapter tube 100, and disposed within the adapter body 102, thereby being protected and sealed off from the environment.

[0019] In various embodiments, in-line adapter tubes are configured to receive optical fiber cables of various sizes. Various embodiments disclosed herein may include “off the shelf” components such as O-rings, Sealcon fittings, and Sealcon nuts.

[0020] This disclosure is not limited to the particular systems, devices and methods described, as these may vary. The terminology used in the description is for the purpose of describing the particular versions or embodiments only, and is not intended to limit the scope.

[0021] In the above detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be used, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.

[0022] The present disclosure is not to be limited in terms of the particular embodiments described in this application, which are intended as illustrations of various aspects. Many modifications and variations can be made without departing from its spirit and scope, as will be apparent to those skilled in the art. Functionally equivalent methods and apparatuses within the scope of the disclosure, in addition to those enumerated herein, will be apparent to those skilled in the art from the foregoing descriptions. Such modifications and variations are intended to fall within the scope of the appended claims. The present disclosure is to be limited only by the terms of the appended claims, along with the full scope of equivalents to which such claims are entitled. It is to be understood that this disclosure is not limited to particular methods, reagents, compounds, compositions or biological systems, which can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.

[0023] As used in this document, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art. Nothing in this disclosure is to be construed as an admission that the embodiments described in this disclosure are not entitled to antedate such disclosure by virtue of prior invention. As used in this document, the term “comprising” means “including, but not limited to.”

[0024] While various compositions, methods, and devices are described in terms of “comprising” various components or steps (interpreted as meaning “including, but not limited to”), the compositions, methods, and devices can also “consist essentially of” or “consist of” the various components and steps, and such terminology should be interpreted as defining essentially closed-member groups.

[0025] With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

[0026] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

[0027] In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

[0028] As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art all language such as “up to,” “at least,” and the like include the number recited and refer to ranges which can be subsequently broken down into subranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 cells refers to groups having 1, 2, or 3 cells. Similarly, a group having 1-5 cells refers to groups having 1, 2, 3, 4, or 5 cells, and so forth.

[0029] Various of the above-disclosed and other features and functions, or alternatives thereof, may be combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art, each of which is also intended to be encompassed by the disclosed embodiments.
