Abstract
The utility model discloses a flame-retardant and fireproof communication optical cable that is characterized in that a stainless steel wrinkled optical unit is arranged inside the optical cable. A varied number of optical fibers are arranged inside the stainless steel wrinkled optical unit according to the message capacity; and the stainless steel wrinkled optical unit is formed by combination of optical fibers and waterproof fiber pastes, wherein the space around the fibers are filled with the waterproof fiber pastes. According to the utility model, the provided optical cable with advantages of compact structure, small external diameter and light weight has functions of communication, data and graphic transmission and the like as well as performances of inflaming retarding, fire resistance, cold resistance, ozone resistance, atmospheric aging resistance, chemical corrosion resistance, low-temperature flexibility, and heat resistance and stability and the like. Therefore, signal transmission like communication transmission, data transmission and graphic transmission and the like can be realized. And the provided optical cable is suitable for communication and data communication in environments of inflaming retarding and fire resistance and the like.
Description
Technical field
The utility model relates to a kind of communications optical cable, especially relates to a kind of flame-retardant communications optical cable, belongs to the optical signal transmission technical field.
Background technology
Existing communications optical cable belongs to the optical signal transmission technical field, and former communications optical cable is moulds sleeve pipe ointment filled plastics sheath structure, and its lateral pressure resistant is little, and the product external diameter is big, and is fire-retardant, fire performance is poor, and environmental resistance is poor.
A kind of fire-retardant cable that improves structure is arranged in the prior art; Comprise---optical cable low smoke and zero halogen polyethylene sheath, place stainless steel light unit or plastic casing light unit in the optical cable protective layer to be used to protect optical fiber moistureproof and receive wall pressure; Characteristics are to extrude the combustion of prolonging that one deck low smoke and zero halogen polyethylene sheath can prevent optical cable outside stainless steel light unit or the plastic casing light unit; But this optical cable only has and prevents to prolong the combustion function; Do not have good fire-retardant and fire-resistant function,, need to increase fire-retardant fireproof layer structure if will realize fire-resistant function.
The utility model content
The utility model technical matters to be solved provide a kind of simple in structure, be applicable to optical signal transmission be used for communicating by letter and data transmission system of fire-retardant and fire-resistant environment.
In order to reach above-mentioned technical purpose, the technical scheme that the utility model adopts is: a kind of flame-retardant communications optical cable, comprise cable core, and said cable core is stainless steel wrinkle light unit, said stainless steel wrinkle light unit is to fill the fine cream that blocks water around the optical fiber to be combined into;
Said stainless steel wrinkle light unit outwards is provided with fire-resistant cladding and silicon rubber sheath successively;
Vertically place two phosphatization steel wires in the said silicon rubber sheath;
Said optical fiber is colored optical fiber G.651 or G.652 or G.657.
Described flame-retardant communications optical cable, stainless steel wrinkle light unit takes the wrinkle structure can increase the flexibility of this optical cable.
Said wrapped fire-resistant cladding, can be used for fire-retardant and fire-resistant, along with temperature raises; Flame retardant coating will form tight hard, complete housing rapidly; The ablation time is long more, and temperature is high more, and is hard more; Hard housing after the burning plays well fire-resistant, thermal insulation protection effect to stainless steel wrinkle light unit, can ensure the short time transmitting optical signal of circuit under fire condition.
Said optical cable protective layer adopts silastic material, has cold-resistant, anti-ozone, anti-atmospheric aging, resistance to chemical attack, low-temperature resistant flexile, heat-resisting performance such as stable.
Vertically place two phosphatization steel wires in the said silicon rubber sheath, have good longitudinal load-bearing ability.
The beneficial effect of the utility model: the utility model has been realized the fire-retardant and fire-resistant function of communications optical cable; Be applicable to communication and data transmission with environment such as fire-retardant, fire-resistant; Have compact conformation, external diameter is little, in light weight; Advantage easy, that the life-span is long is installed, laid to fire-retardant, fire-resistant, cold-resistant, anti-ozone, anti-atmospheric aging, resistance to chemical attack, low-temperature resistant flexile, heat-resisting performance such as stable.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Wherein: 1 optical fiber; The 2 fine cream that block water; 3 stainless steel wrinkle light unit; 4 fire-resistant claddings; 5 phosphatization steel wires; 6 silicon rubber sheaths.
Embodiment
Below in conjunction with accompanying drawing and instantiation the utility model is further described.
As shown in the figure; A kind of flame-retardant communications optical cable; Comprise stainless steel wrinkle light unit 3, in said stainless steel wrinkle light unit 3, be provided with and fill the fine cream 2 that blocks water around the optical fiber 1, optical fiber and be combined into stainless steel wrinkle light unit that optical fiber adopts colouring discrimination so that install; Said stainless steel wrinkle light unit 3 outer fire-resistant cladding 4 and the silicon rubber sheaths 6 of being followed successively by are vertically placed two phosphatization steel wires in the silicon rubber sheath 6; Stainless steel wrinkle light unit 3 external diameters are 3.0mm, and flame retardant coating thickness is 1.0 mm, and silicon rubber sheath thickness is 2.0mm, and its two phosphatization steel wire external diameters vertically placing are 1.2mm; Total external diameter of said optical cable is 9mm.
Above-mentioned instance also can increase the built-in fiber number through adjustment stainless steel wrinkle light unit external diameter, satisfies the different communication of user, data, figure transmission requirement.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replacement or the technical scheme that obtained of equivalent transformation mode, all drop within the protection domain of the utility model.
