Problems solved by technology

The optical cable used in this deployment scheme is generally a central strength member optical cable. The strength member is located in the center of the cable core and is surrounded by loose tubes. Therefore, the number of loose tubes is generally large, and the number of optical fibers in the loose tube is also large. The weight of the cable is generally large, and it is difficult to strip and weld when connecting branches at different user ends, which affects the construction efficiency
In addition, the fiber optic cable has a large diameter and is difficult to route in existing narrow ducts

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] see figure 1 As shown, the present invention provides a non-central strength member optical cable, including a sheath layer 1 , a strength member 2 and a loose tube 3 .

[0026] The sheath layer 1 is sleeved on the strength member 2 and the loose tube 3, there are at least two strength members 2, and at least one loose tube 3, and the overall cross section of the optical cable is circular. Both the loose tube 3 and the reinforcement 2 are located in the sheath layer 1 , wherein each reinforcement 2 is located in a non-central position in the sheath layer 1 . In the present invention, there is one loose tube 3 and two reinforcing members 2. Since the present invention adopts the non-central reinforcing member structure, only one loose tube 3 is arranged in the optical cable, instead of multiple loose tubes surrounding and strengthening the conventional...

Abstract

The invention discloses an optical fiber cable provided with non-central strengthening parts and relates to the field of communication wires and cables. The optical fiber cable comprises a jacket layer, as well as at least two strengthening parts and at least one loose tube which are arranged in the jacket layer, wherein each strengthening part is located in a non-central position in the jacket layer, and the strengthening parts and the loose tube are sleeved with the jacket layer. The optical fiber cable provided with the non-central strengthening parts is stripped and connected easily, high in laying efficiency, compact in structure and small in cross section, and is arranged easily in the conventional narrow pipelines.

Description

technical field [0001] The invention relates to the field of communication cables, in particular to a non-central strength member optical cable. Background technique [0002] With the rapid expansion of FTTx (Fiber-to-the-x, fiber optic access) construction, more and more residential areas and office buildings use fiber optic access to access the Internet. The current FTTx deployment scheme is to connect the large-core optical cable with the LAN optical cable and the drop optical cable, and then import it to the end user. The optical cable used in this deployment scheme is generally a central strength member optical cable. The strength member is located in the center of the cable core and is surrounded by loose tubes. Therefore, the number of loose tubes is generally large, and the number of optical fibers in the loose tube is also large. The weight of the cable is generally large, and it is difficult to strip and weld when branching at different user terminals, which affec...
