Description

Adapter assembly for fiber optic cables

Technical Field

The present application relates to an adapter assembly for fiber optic cables.

Background

Optical performance verification of optical fiber cables can be performed during the manufacturing process of the optical fiber cables, or in the inspection of the product quality of the optical fiber cables, or when the optical fiber cables are used. The optical fiber cable may be provided with an optical fiber connector on at least one end thereof. Flat ribbon connectors for fiber optic cables, hardened multi-fiber connectors (HMFOC), MPO connectors, and the like are known in practice, for example. Various fiber optic cables with various fiber optic connectors may have different losses, such as different insertion losses, which may be used as the performance parameters to be measured for the fiber optic cable being measured. In addition, different types of connectors may not be connectable to each other.

Fig. 1 and 2 describe a detection device for a fiber optic cable and a corresponding detection method known in practice.

As shown in fig. 1, in performing an optical test on the optical fiber cable 5 under test, the optical fiber cable 5 under test is connected between the light source 1 and the optical power meter probe 7. In practice, it is generally necessary to connect a reference optical fibre cable 2 between the light source 1 and the optical fibre cable 5 to be tested, in order to avoid or reduce plugging at the joint of the light source 1, thus minimizing the wear at this joint.

Before the optical test of the optical fiber cable 5 under test, it is usually necessary to perform a reference zeroing and stability test on the reference optical fiber cable 2 to remove test errors caused by optical loss of the reference optical fiber cable 2 and to test its stability. The reference fibre optic cable 2 typically has a fibre optic connector 3 (e.g. an HMFOC connector) at one end for connection to a fibre optic cable 5 to be tested, for connection with a corresponding fibre optic connector 4 on the fibre optic cable 5 to be tested. The fiber optic cable 5 under test is then typically connected to the optical power meter probe 7 by means of a ribbon connector 6 mounted on the optical power meter probe 7. However, this ribbon connector 6 is not compatible with the fiber optic connector 3 on the reference fiber optic cable 2, and thus the reference fiber optic cable 2 cannot be tested and the appropriate reference zeroing and stability tests by directly connecting the fiber optic connector 3 on the reference fiber optic cable 2 with the ribbon connector 6. To this end, typically, in the prior art, the fiber optic connector 3 of the reference fiber optic cable 2 is first disassembled, then the reference fiber optic cable 2 is temporarily configured with the MPO connector 8, and the ribbon connector 6 of the optical power meter probe 7 is temporarily replaced with the corresponding MPO connector 9. After testing the reference fiber optic cable 2 for reference zeroing and stability testing, the temporarily configured MPO connector 8 is removed from the reference fiber optic cable 2, restored to the original fiber optic connector 3, and the temporarily configured corresponding MPO connector 9 of the optical power meter probe 7 is restored to the original ribbon connector 6. Such an operation is cumbersome and time consuming.

SUMMERY OF THE UTILITY MODEL

Exemplary embodiments of the present application are described in detail below with reference to the accompanying drawings.

The present application relates to an adapter assembly 10 for a fiber optic cable, the adapter assembly 10, for example, may be configured for optical testing (e.g., performing a reference zeroing, stability test, etc.) of the fiber optic cable. The optical fiber cable may be, for example, a reference optical fiber cable 2 for an optical fiber cable 5 to be tested. The adapter assembly 10 may be configured for connecting the fiber optic connector 3 of the end of the reference fiber optic cable 2 to be connected to the fiber optic cable 5 to be tested to the optical power meter probe 7. The optical fiber connector may be, for example, a hardened multi-fiber connector (HMFOC). The hardened multi-fiber connector may be of the plug type (male) or the receptacle type (female).

As shown in fig. 5 to 11, the adapter assembly 10 includes a first adapter 100 and a second adapter 200. The first adapter 100 is configured for connection to an optical power meter probe 7. The second adapter 200 is configured for receiving at least a portion of a fiber optic connector 3 (e.g., HMFOC) of a fiber optic cable (e.g., reference fiber optic cable 2). In use, the first adapter 100 receives the second adapter 200. When the first adapter 100 is connected with the optical power meter probe 7, the second adapter 200 receives the optical fiber connector 3, and the second adapter 200 is received in the first adapter 100, a communicative optical path can be formed between the optical fiber connector 3 and the optical power meter probe 7.

As shown in fig. 5 to 7, the first adapter 100 may include a receiving portion 101, a connecting portion 102, and a plate 103. The receiving portion 101 of the first adapter 100 has a first receiving cavity 110, the first receiving cavity 110 being configured for receiving the second adapter 200.

The first adapter 100 and the second adapter 200 may be configured to mate against rotation. For example, the receiving portion 101 may have a first plane 117, the first plane 117 defining a portion of a peripheral wall of the first receiving chamber 110. Accordingly, the second adapter 200 may have a second plane 201 (see fig. 8). The second flat surface 201 and the first flat surface 117 may cooperate when the second adapter 200 is engaged or disengaged with the first adapter 100. In alternative embodiments, the first receiving chamber 110 and the second adapter 200 may be configured to have other non-circular cross-sections. In this case, the second adapter 200 can advantageously be inserted into the first receiving chamber 110 only in a predetermined angular position relative to the first receiving chamber 110, so that a single predetermined angular position of the second adapter 200 with respect to the first adapter 110 is achieved.

As shown in fig. 7, the receiving portion 101 of the first adapter 100 may include a cylindrical body portion 111 and a neck portion 112. The cylindrical body part 111 has the first receiving chamber 110 already mentioned, and the cylindrical body part 111 merges via an annular surface 113 into a neck 112. This annular surface 113 may form an axial stop for the second adapter 200, so that the second adapter 200 has a unique predetermined terminal axial position relative to the first adapter 100.

As shown in fig. 6 and 7, the neck 112 of the receiving portion 101 of the first adapter 100 may have a first bore segment 114 surrounded by an annular face 113. Corresponding to the first bore section 114, as shown in fig. 8, the second adapter 200 can have an axial projection 202 on its end side facing the first adapter 100. When the second adapter 200 is received in the first receiving chamber 110, the axial protrusion 202 may be received in the first bore section 114 (see fig. 12). The neck 112 of the receiving portion 101 of the first adapter 100 may also have a second reduced diameter bore section 115 immediately adjacent the first bore section 114. Alternatively or additionally, the annular surface 116 between the first bore section 114 and the second bore section 115 may abut against the axial projection 202 of the second adapter 200 to form an axial stop for the second adapter 200.

The connection portion 102 of the first adapter 100 may be configured for connecting the first adapter 100 to the optical power meter probe 7. In some embodiments, the connection portion 102 may have an internal thread 120, the internal thread 120 being configured for screwing to the optical power meter probe 7.

As shown in fig. 5 and 7, the plate 103 of the first adapter 100 may be positioned between the receiving portion 101 and the connecting portion 102 in the axial direction and include a through opening 130 therethrough. When the adapter assembly 10 connects the fiber optic connector 3 to the optical power meter probe 7, an optical path can be formed between the fiber optic connector 3 and the optical power meter probe 7 through the through opening 130. In some embodiments, the through opening 130 may be configured to allow only a length of the end portion of the fiber optic connector 3 to pass therethrough.

As shown in fig. 5, the plate 103 may have positioning pins 131 such that the plate 103 may have a predetermined angular position relative to the optical power meter probe 7 when the first adapter 100 is connected with the optical power meter probe 7. For example, the plate 103 may have three locating pins 131 evenly distributed around the through opening 130.

Advantageously, the receiving portion 101, the connecting portion 102 and the plate 103 of the first adapter 100 may each be constructed as separate components. As shown in fig. 5, the separate plate 103 may be detachably fastened to the receiving portion 101 by three screws 132, e.g. fixed on the end side of the neck 112.

The connecting part 102 can be movably fitted on the neck 112 and the plate 103 can have a rim portion 133 projecting radially from the neck 112, which rim portion 133 can cooperate with the inner flange 121 of the connecting part 102 to form an axial stop for the connecting part 102, so that the connecting part 102 can be held captive on the receiving part 101. The connecting portion 102 is movable along the neck 112 in an axial direction between an extended position and a retracted position.

As shown in fig. 8-10, the second adapter 200 may include a second receiving cavity 203, and the second receiving cavity 203 may be configured to receive at least a portion of the fiber optic connector 3. As shown in fig. 12, the second receiving cavity 203 may be configured to receive at least a portion of a hardened multi-fiber connector (HMFOC) wherein a housing of the HMFOC connector has been removed. The HMFOC connector with the housing 301 and the HMFOC connector with the housing 301 removed are shown in fig. 13 and 14, respectively.

The second receiving chamber 203 may be configured to have a cross-sectional shape that fits with the at least a portion of the optical fiber connector 3 such that the at least a portion of the optical fiber connector 3 can only be inserted into the second receiving chamber 203 in a predetermined angular position relative to the second receiving chamber 203. As shown in fig. 8 and 9, the second receiving chamber 203 may have axially extending grooves 204 opposite each other, which are asymmetrical to each other. In other embodiments not shown, the second receiving cavity 203 may also be configured with other shaped features that uniquely form-fit with at least a portion of the fiber optic connector.

As shown in fig. 10, an end side of the second receiving chamber 203 (axial protrusion 202) of the second adapter 200 facing the first adapter may be provided with a stop 205, e.g. an internal flange, extending radially inwards for positioning the at least one portion of the fiber optic connector 3 in the axial direction.

The second adapter 200 may further comprise a pair of grips 206 protruding from a second end side thereof facing away from the first adapter 100, thereby facilitating a user to insert and extract the second adapter 200 into and from the first adapter 100.

In other embodiments not shown, the adapter assembly 10 may further include a first magnet disposed in the first adapter 100 and a second magnet disposed at a corresponding location in the second adapter 200 to maintain the first adapter 100 and the second adapter 200 engaged with a predetermined magnetic attraction when the first adapter 100 and the second adapter 200 are engaged. The first adapter 100 and the second adapter 200 can be separated at least after overcoming this magnetic attraction.

In an exemplary embodiment, as shown in fig. 3 and 4, when performing the reference zeroing and stability test on the reference fiber optic cable 2 having the HMFOC connector, at most the housing of the HMFOC connector needs to be removed without having to disassemble and temporarily modify the HMFOC connector into an MPO connector. The installation of the reference fibre optic cable 2 on the optical power meter probe 7 is completed by connecting the first adapter 100 directly to the optical power meter probe 7 and connecting the first adapter 100 and the second adapter 200 together. After the test is completed, the reference fiber optic cable 2 can be recovered by disconnecting the second adapter 200 from the first adapter 100 and disconnecting the reference fiber optic cable 2 from the second adapter 200, and then fitting the housing of the HMFOC connector back to the HMFOC connector. Subsequently, the reference optical fiber cable 2 may be connected with the optical fiber cable 5 to be tested. In a further particularly advantageous embodiment, the fiber optic cable 5 under test can continue to be connected to the optical power meter probe 7 using the first adapter 100 without having to replace the first adapter 100 already connected to the optical power meter probe 7.

From the above description, it is clear that the adapter assembly 10 according to the present application is capable of directly connecting a fiber optic cable, e.g. an HMFOC connector, of the one end of a reference fiber optic cable to the optical power meter probe 7, thereby enabling a connection operation to the fiber optic cable to be significantly simplified. For example, when reference zeroing and stability testing is performed on the reference fiber optic cable 2, the time required for the test can be significantly saved. The adapter assembly 10 according to the present application is easy to manufacture and simple to operate. Furthermore, it is also possible that in a further advantageous embodiment the first adapter 100 in the adapter assembly 10 can also be used for subsequent testing of the fiber optic cable 5 to be tested without having to replace the splice on the optical power meter probe 7 for this purpose.

Although exemplary embodiments of the present application have been described, it will be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present application without substantially departing from the spirit and scope of the present application. Accordingly, all such changes and modifications are intended to be included within the scope of the present application.
