The protective groove device of the line and optical fiber active connector 201.

[0049] Wherein the butterfly-shaped lead-in optical cable 101 includes an optical fiber 1013, an outer sheath 1014, a strength member 1011 and a microcable unit 1012, the microcable unit 1012 is arranged on the outer layer of the optical fiber 1013, and the outer sheath 1014 wraps On the outer ring surface of the microcable unit 1012, the strengthening member 1011 is disposed parallel to both sides of the microcable unit 1012, and the strengthening member 1011 ensures the overall strength of the entire optical fiber cable.

[0050] The optical fiber active conne...

Embodiment 2

[0058] A preparation method based on the prefabricated end butterfly drop cable described in embodiment 1, comprising the steps of:

[0059] S1: Stripping the outer sheath 1014 of the prefabricated-end butterfly-shaped lead-in optical cable with a fiber stripping or cable stripping tool;

[0060] S2: thread the tail sleeve 2011, the stopper 2012, and the spring 2013 of the optical fiber active connector 201 into the microcable unit 1012 in sequence;

[0061] S3: Fixing the length of the microcable unit 1012 according to the length used;

[0062] S4: Clean and pre-treat the end face of the optical fiber with a clean alcohol cloth and an optical fiber cutter;

[0063] S5: inserting the ceramic ferrule 2014 with glue, and placing it in a curing furnace for curing, wherein the ceramic ferrule 2014 has a tailstock;

[0064] S6: Assemble white inner core 2015 and SC outer shell 2016;

[0065] S7: After the assembly is completed, the end face of the optical fiber is polished;

[...

Embodiment 3

[0071] A wiring method based on the prefabricated end butterfly lead-in optical cable described in embodiment 1, comprising the following steps:

[0072] E01: Install the optical fiber active connector 201 into the protective groove device to avoid bending and damage to the micro cable unit 1012 during wiring;

[0073] E02: After delivering the optical fiber active connector 201 to the designated area, take the optical fiber active connector 201 out of the protective slot, and strip the outer sheath 1014 of the butterfly-shaped lead-in optical cable 101 to the required length, and remove the stripped outer sheath. The sheath 1014 is cut;

[0074] E03: The stripped 900um micro-cable unit 1012 is coated with a hot-melt glue gun along the wiring route (as far as possible along the corner of the wall), and embedded in the fine groove of the ceiling or wall;

[0075] E04: Insert the optical fiber active connector 201 into the device, fix the butterfly-shaped lead-in optical cable ...

Abstract

The present invention discloses a prefabricated formed butterfly introduction optical cable, a manufacture method thereof and a wiring method thereof. According to the invention, the characteristics of inner optical fiber cords and self-supporting butterfly optical cables are combined, and the prefabricated formed butterfly introduction optical cables are employed at the outdoor introduction, wherein the butterfly introduction optical cables are convenient to cross and connect wires under construction because of the structure characteristic of the butterfly introduction optical cables so that the optical fibers in the cables are protected very well. After introducing into the indoor space, wiring units are converted to micro-cable units of 900 [mu]m so as to greatly reduce the wiring areas, and the places where the wiring can be not performed before may be wired. Compared with the conventional butterfly introduction optical cables, the rate of finished products and the production efficiency of the prefabricated formed butterfly introduction optical cables with the structure are greatly improved, and the micro-cable units of 900 [mu]m after decorticating may be manufactured as the conventional optical fiber connector, therefore avoiding a series of unbridgeable problems in the production process of the conventional prefabricated formed butterfly introduction optical cables.

Description

technical field [0001] The invention relates to the technical field of optical fiber access, in particular to a prefabricated end butterfly lead-in optical cable which can be laid invisible and a preparation and wiring method thereof. Background technique [0002] With the large-scale construction of FTTH urban optical networks, butterfly drop cables are widely used. The butterfly cable is used as the transmission medium between the central office and the user, and the optical fiber connector is used as the connecting device to realize the fast connection of the optical link between the home and the corridor. Among them, there are mainly two ways to realize the connection between the butterfly-shaped lead-in optical cable and the optical fiber connector, one is the cold splicing technology of the optical fiber quick connector and the butterfly-shaped lead-in cable, and the other is the prefabricated end technology (i.e. The fiber optic connector is fixed on the butterfly dr...
