Description

Technical Field

[0001] The present application relates to the technical field of data center communication optical cables, and in particular to a fire-resistant communication optical cable for data center transmission. Background Art

[0002] With the rapid development of information technology, optical cables, as an important medium for data transmission, play a vital role in various communication systems. However, in actual use, optical cables may cause fires due to external environmental factors, which may lead to communication interruption and data loss, and may even cause serious safety accidents. Therefore, it is particularly important to improve the fire resistance of optical cables.

[0003] With the advancement of technology, there are now some optical cables with fire-proof functions. These optical cables usually achieve fire-proof purposes by setting up fire-proof protective layers or equipping sensors. Fire-proof protective layers such as alumina fiber belts or ceramic silicone rubber sheaths can delay the spread of flames to a certain extent. Sensors can quickly alarm when a fire occurs, allowing operators to take emergency measures in time to reduce losses.

[0004] However, the fire prevention effects of the above two fire prevention settings are not ideal. They can only passively prolong the speed of optical cable damage, but cannot eliminate the fire point, and cannot meet the growing demand for optical cable functions. The existing communication optical cables often ignore the initiative of fire extinguishing in their design and lack an effective and autonomous fire extinguishing mechanism, which still poses a great safety hazard when facing high temperature and flames.

[0005] Therefore, it is necessary to provide a fire-resistant communication optical cable for data center transmission to solve at least one of the above technical problems. Summary of the invention

[0006] In order to solve the above problems, the optical cable has a certain fire extinguishing ability in addition to passively extending the burning time. The present application provides a fire-resistant communication optical cable for data center transmission.

[0007] The fire-resistant communication optical cable for data center transmission provided in this application adopts the following technical solution: A fire-resistant communication optical cable for data center transmission, comprising: A number of cable cores; A cross bearing plate, bearing the cable core, wherein a plurality of the cable cores are arranged on the cross bearing plate at equal intervals, and the cross bearing plate separates the plurality of the cable cores; The fire-resistant component is arranged on the cross-bearing plate, and the fire-resistant component provides fire-resistant protection for several cable cores; wherein, The fire-resistant assembly includes a plurality of fire extinguishing frames, wherein a fire extinguishing agent is arranged inside the fire extinguishing frames, both ends of the fire extinguishing frames are opened, and a fuse surface is arranged at the opening, and the fuse surface can be burned and melted to release the fire extinguishing agent, and the upper and lower end surfaces of the cross bearing plate are both provided with a plurality of placement recesses, and the fire extinguishing frames are arranged in the placement recesses; A plurality of groups of protective sleeves are provided at the cross bearing plate to wrap and protect the cable core, and the plurality of groups of protective sleeves can be spliced ​​together.

In case of fire, the cable cores are fire-resistantly protected by several groups of protective sleeves to maintain the protection of the cable cores under a certain temperature or fire intensity. When the fire burns from the optical cable to the cable core, the fire burns to the cross-bearing plate and burns the fusible sections at the openings at both ends of the fire extinguishing frame. After the fusible sections are melted by the fire, the fire extinguishing agent in the fire extinguishing frame is depressurized and sprayed out to act near the surface of the cable core, thereby extinguishing the fire of the cable core at the fire site, avoiding the spread of fire caused by the cable core catching fire in some areas, and extending the fire area of ​​the optical cable.
