Fig. 1 is an overall schematic diagram of a separable composite drop fiber according to one embodiment of the present invention. In fig. 1, the separable composite drop fiber may include a flexible stopper 01, a main strength member 02, and an insulating sheath 03.
The flexible stopper 01 may have a structure as shown in fig. 2, for example. In fig. 2, the flexible limiting member 01 may be a cylinder having at least one groove 011 formed on a side surface thereof for fixing the optical cable main body 04, and the axis of the cylinder may be hollow 012, and the radius of the groove 011 may be larger than that of the optical cable main body 04, so that the optical cable main body 04 may be snapped into the groove 011. (ii) a
The main strength member 02 may be disposed in the hollow 012 of the flexible limiting member 01 for protecting the optical cable main body 04 from being bent excessively. The insulating protective sheath 03 can be disposed on the periphery of the flexible limiting member 01, and includes a buckle 031 for fixing the insulating protective sheath 03.
In one embodiment of the present invention, the cable body 04 may be a variety of types of optical cables known to those skilled in the art. In one example of the present invention, the cable body 04 may be, for example, as shown in fig. 3. In FIG. 3, the cable body 04 may include a secondary strength member 041, a fiber optic ferrule 042, an inner insulating jacket 043, and an optical fiber 044.
The optical fiber sleeve 042 may be disposed on the periphery of the secondary reinforcing member 041, and a core filler may be disposed between the secondary reinforcing member 041 and the optical fiber sleeve 042. The optical fiber 044 may be disposed inside a fiber optic ferrule 042. An inner insulating sleeve 043 may be used to encase the light sleeve 042 and the secondary strength member 041.
In one embodiment of the present invention, a pressure sensitive element 021 may be disposed at a central axis of the main strength member 02, and the pressure sensitive element 021 may be used to determine a degree of bending of the separable composite type drop cable in real time. In addition, considering that the main reinforcement 02 is cylindrical, the pressure sensitive elements 021 may be plural and connected in series, and the arrangement may be, for example, as shown in fig. 4.
Furthermore, the insulating protective sheath 03 may be formed of a fire-resistant material in consideration of the need to ensure fire protection of the separable composite drop cable. Preferably, the insulating protective sheath 03 can be a low smoke halogen-free flame retardant sheath.
In another aspect, the invention further provides a signal interaction system. As shown in fig. 5, the signal interaction system may include a separable composite drop cable T, a first communication port a1, and a second communication port a 2. The second communications port a2 may be used to connect with the first communications port a1 via a separable composite drop cable T. The separable composite drop cable T may then be of the construction illustrated in fig. 1-4, for example. Specifically, the separable composite drop fiber may include a flexible stopper 01, a main strength member 02, and an insulating sheath 03.
The flexible stopper 01 may have a structure as shown in fig. 2, for example. In fig. 2, the flexible limiting member 01 may be a cylinder having at least one groove 011 formed on a side surface thereof for fixing the optical cable main body 04, and the axis of the cylinder may be hollow 012, and the radius of the groove 011 may be larger than that of the optical cable main body 04, so that the optical cable main body 04 may be snapped into the groove 011. (ii) a
The main strength member 02 may be disposed in the hollow 012 of the flexible limiting member 01 for protecting the optical cable main body 04 from being bent excessively. The insulating protective sheath 03 can be disposed on the periphery of the flexible limiting member 01, and includes a buckle 031 for fixing the insulating protective sheath 03.
In one embodiment of the present invention, the cable body 04 may be a variety of types of optical cables known to those skilled in the art. In one example of the present invention, the cable body 04 may be, for example, as shown in fig. 3. In FIG. 3, the cable body 04 may include a secondary strength member 041, a fiber optic ferrule 042, an inner insulating jacket 043, and an optical fiber 044.

The optical fiber 044 may be disposed inside a fiber optic ferrule 042. An inner insulating sleeve 043 may be used to encase the light sleeve 042 and the secondary strength member 041.
During the cable laying process, it is often necessary to test the signal loss rate of the cable. In the case of a large signal loss rate, the optical cable may be bent to an excessive degree or a portion of the optical cable may be damaged. However, to further identify the specific problems existing at this time, the prior art only relies on human judgment, and in case that the human judgment is not available, the line can only be re-laid, which greatly restricts the efficiency of laying the optical cable. Therefore, in one embodiment of the present invention, a pressure sensitive element 021 may be disposed at a central axis of the main strength member 02, and the pressure sensitive element 021 may be used to determine a degree of bending of the separable composite type drop cable in real time. In addition, considering that the main reinforcement 02 is cylindrical, the pressure sensitive elements 021 may be plural and connected in series, and the arrangement may be, for example, as shown in fig. 4. Therefore, under the condition of large signal loss rate, whether the optical cable has the problem of overlarge bending degree or not is determined, and if the optical cable has the problem, the reason why the signal loss rate is large at the moment is that the optical cable has the overlarge bending degree; if the optical cable does not exist, the reason why the signal loss rate is larger at this time is because the optical cable itself may have a problem of partial damage. Further, in the case where the separable composite drop optical fiber includes the pressure sensitive element 021, the first communication terminal a1 and/or the second communication terminal a2 may be electrically connected to the pressure sensitive element 021 for acquiring a degree of bending of the separable composite drop optical cable T through the pressure sensitive element 021 and stopping the communication operation in the case where it is determined that the degree of bending is excessively large. And the specific manner of determining the degree of bending for the first communication terminal a1 and/or the second communication terminal a2 can be various manners known to those skilled in the art. In a preferred example of the present invention, the specific manner of determining the degree of bending may be, for example, the step shown in fig. 6. In fig. 6, the specific manner may include:
in step S01, the standard resistance value of the pressure sensitive element when the separable composite drop cable is at the standard position is determined. Wherein the standard position may be a state where the separable composite drop fiber maintains a minimum signal loss ratio (typically, the fiber is in an unbent state).
In step S02, the current real-time resistance value of the pressure-sensitive element is determined.
In step S03, the difference between the real-time resistance value and the standard resistance value is calculated.
In step S04, it is determined whether the difference is greater than a preset threshold.
In step S05, in the case where the difference is judged to be larger than the threshold value, it is determined that the degree of bending is too large.
In step S06, in the case where it is determined that the difference is less than or equal to the threshold, the current communication operation is continued.
Through the technical scheme, the separable composite leading-in optical cable and the signal interaction system provided by the invention fix the optical cables by arranging the flexible limiting part, the main reinforcing part and the insulating protective sleeve, so that the sandstone can not enter gaps of the optical cables under the condition of laying the optical cables.
