Problems solved by technology

[0002] Optical cable is one of the essential communication devices in our daily life. Because some optical cables are buried underground for a long time, they are eroded by underground moisture for a long time, and they are prone to poor communication quality; some optical cables Working under the sun for a long time will cause aging and sheath falling off, which will easily lead to short-circuit fire accidents, and there are great potential safety hazards

Embodiment Construction

[0012] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0013] like figure 1 The shown multi-core waterproof optical cable of the present invention has an optical cable sheath 5, and the interior of the optical cable sheath 5 is provided with multiple groups of optical fibers 1 in parallel, and the exterior of each group of optical fibers 1 is sequentially coated with loose tubes 2, resistance Water glass fiber 3 and polyethylene sheath 4; the space between the optical cable sheath 5 and multiple polyethylene sheaths 4 is filled with water blocking glass fiber 3.

[0014] Wherein, the optical cable sheath 5 is made of PE material, which protects the combination of multiple groups of optical fibers 1 as a whole, an...

Abstract

The invention relates to the technical field of optical cables, and relates to a multi-core waterproof optical cable. The multi-core waterproof optical cable comprises an optical cable sheath. Multiple optical fibers are arranged inside the optical cable sheath in parallel and in a penetrating way. Each optical fiber is coated with a loose casing, a water-blocking glass fiber and a polyethylene sheath sequentially from inside to outside. Water-blocking glass fibers fill the space between the optical cable sheath and the multiple polyethylene sheaths. The multi-core waterproof optical cable has an excellent waterproof effect, and has high resistance to high temperature.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to a multi-core waterproof optical cable. Background technique [0002] Optical cable is one of the essential communication devices in our daily life. Because some optical cables are buried underground for a long time, they are eroded by underground moisture for a long time, and they are prone to poor communication quality; some optical cables Working under the sun for a long time will cause aging and the sheath will fall off, which will easily lead to short-circuit fire accidents, and there are great potential safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problems raised in the above-mentioned background technology, the present invention provides a multi-core waterproof optical cable, which not only has excellent waterproof effect, but also has good high temperature resistance.
