Embodiment 1

[0033] Please refer to figure 1 , the present embodiment provides a fully dry optical cable 100, including a cable core 110 and an outer sheath 120 disposed on the outer layer of the cable core 110, and the outer sheath 120 protects the cable core 110 from external damage.

[0034] The cable core 110 includes a modified PBT loose tube 111, a reinforcing member 112 and a water-blocking tape 113. The reinforcing member 112 is arranged at the center of the cable core 110 to play a role of stable support, so that the fully dry optical cable 100 can withstand a certain external force. enhance its mechanical properties. In this embodiment, the reinforcing member 112 is made of fiber-reinforced composite material into a cylindrical shape. In other embodiments of the present invention, the material and shape of the reinforcing member 112 may be in other forms, which are not limited in the present invention.

[0035] The modified PBT loose tube 111 is disposed on the outer periphery o...

Embodiment 2

[0044] Please refer to figure 2 , this embodiment provides a fully dry optical cable 200 .

[0045] The main differences between the fully dry optical cable 200 and the fully dry optical cable 100 are:

[0046] An aramid fiber 210 and a tearing rope 220 are also provided between the cable core 110 and the outer sheath 120 of the fully dry optical cable 200 . Specifically, the aramid fiber 210 is disposed between the water blocking tape 113 and the outer sheath 120 . Aramid 210 is a new type of synthetic fiber with excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight, insulation, anti-aging, and long life cycle. It enhances the performance of dry optical cable 200. The tearing rope 220 enhances the pulling resistance of the fully dry optical cable 200, reduces the damage rate, and can also absorb the heat emitted by the fully dry optical cable 200 during use, so that the outer sheath 120 is remo...

Embodiment 3

[0049] Please refer to image 3 , this embodiment provides a fully dry optical cable 300 .

[0050] The main differences between the fully dry optical cable 300 and the fully dry optical cable 200 are:

[0051] Since the price of aramid fiber 210 is slightly higher, the use of aramid fiber 210 can be eliminated for small-span optical cables, the tearing rope 220 is arranged on the water blocking belt 113, and TFRP310 is placed symmetrically on both sides of the cable core 110. Specifically, two TFRP310s are symmetrically placed outside the cable core 110 and inside the outer sheath 120, and the force value can also be calculated according to the span of the optical cable, and then the number of TFRP310 placed is selected. In other embodiments of the present invention, the number of TFRP310 It can be 4 or 6, which is not limited in the present invention. Compared with conventional FRP components, TFRP310 is mainly supported by polyethylene fibers, which has high strength, hig...

Abstract

The invention provides a fully dry optical cable and a system thereof, and relates to the technical field of optical cable communication. A fully dry optical cable, including a cable core and an outer sheath arranged on the outer layer of the cable core, the cable core includes a modified polybutylene terephthalate loose tube, a reinforcement and a water blocking tape, and the reinforcement is provided In the center of the cable core, a modified polybutylene terephthalate loose tube is arranged on the outer periphery of the reinforcement, and the water blocking tape covers the modified polybutylene terephthalate loose tube. The optical cable is light in weight, easy to construct, has no damage to the human body and the environment, and has remarkable economy and practicability. An all-dry optical cable system includes the above-mentioned all-dry optical cable. The system is light in weight, easy to construct, has no damage to human body and environment, and has remarkable economy and practicability.

Description

technical field [0001] The invention relates to the technical field of optical cable communication, in particular to a fully dry optical cable and a system thereof. Background technique [0002] In recent years, with the deepening implementation of the "Broadband China" strategy and the active promotion of the information strategy, the network has become a very important information transmission channel in my country. Subsequently, the development of optical cables has also taken a big step forward, and the optical cables are developing towards special, lightweight, and large-capacity structures. [0003] With the rapid development of the communication industry, people's demand for optical cables pays more and more attention to the convenience of construction and environmental friendliness. Because the optical cable contains grease, it is necessary to remove the grease and clean the optical cable before the cable is connected, which makes the operation cumbersome and causes...
