Description
Technical field
The utility model relates to optical cable technology field, particularly relates to a kind of novel high water resistant performance optical cable.
Background technology
Optical cable is that the optical fiber of some forms the cable heart according to certain way, is surrounded by sheath outward, the also coated outer jacket had, in order to realize a kind of communication line of optical signal transmission, that is: and the cable formed through certain technique by optical fiber (optical transmission carrier).Optical cable, in wiring process, often will pass through some moister environment, or even river bed, seabed, this just needs optical cable to have good block-water performance, existing optical cable need in this respect improve.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of novel high water resistant performance optical cable, and have good block-water performance, tensile property is good.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of novel high water resistant performance optical cable, comprise: from the interior middle strengthening core, multiple fiber unit, the packed layer that blocks water, steel band lapping layer, the first water blocking yarn winding layer, aluminium strip lapping layer, the second water blocking yarn winding layer, inner restrictive coating and the external sheath layer that set gradually outward, described fiber unit comprises Loose tube, is arranged on the multifiber in Loose tube and is filled in the fine cream between Loose tube and optical fiber.
In the utility model preferred embodiment, described first water blocking yarn winding layer comprises many first water blocking yarns, and institute's many first water blocking yarn voluble wrappings of telling are outside at described steel band lapping layer.
In the utility model preferred embodiment, described second water blocking yarn winding layer comprises many second water blocking yarns, and institute's many second water blocking yarn voluble wrappings of telling are outside at described aluminium strip lapping layer.
In the utility model preferred embodiment, described in block water packed layer for the cable cream packed layer that blocks water.
In the utility model preferred embodiment, described strengthening core adopts china-hemp fibers to make.
The beneficial effects of the utility model are: the novel high water resistant performance optical cable that the utility model discloses, and have good block-water performance, tensile property is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model novel high water resistant performance optical cable one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, middle strengthening core, and 2, block water packed layer, 3, steel band lapping layer, the 4, first water blocking yarn winding layer, 5, aluminium strip lapping layer, the 6, second water blocking yarn winding layer, 7, inner restrictive coating, 8, external sheath layer, 9, Loose tube, 10, optical fiber, 11, fine cream.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of novel high water resistant performance optical cable, comprise: the middle strengthening core 1, the multiple fiber unit that set gradually outward from interior, the packed layer 2 that blocks water, steel band lapping layer 3, first water blocking yarn winding layer 4, aluminium strip lapping layer 5, second water blocking yarn winding layer 6, inner restrictive coating 7 and external sheath layer 8, the fine cream 11 that described fiber unit comprises Loose tube 9, is arranged on the multifiber 10 in Loose tube 9 and is filled between Loose tube 9 and optical fiber 10.
By the combination of described block water packed layer 2, first water blocking yarn winding layer 4 and the second water blocking yarn winding layer 6, enhance block-water performance of the present utility model.
Described first water blocking yarn winding layer 4 comprises many first water blocking yarns, and institute's many first water blocking yarn voluble wrappings of telling are outside at described steel band lapping layer 3.
Described second water blocking yarn winding layer 6 comprises many second water blocking yarns, and institute's many second water blocking yarn voluble wrappings of telling are outside at described aluminium strip lapping layer 5.
The described packed layer 2 that blocks water is for the cable cream packed layer that blocks water.
Described strengthening core 1 adopts china-hemp fibers to make, and tensile strength is high.
The novel high water resistant performance optical cable that the utility model discloses, have good block-water performance, tensile property is good.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
