Abstract
The utility model discloses a composite anti-interference optical fiber communication control cable, which comprises a wrapping tape layer, wherein the wrapping tape layer is internally provided with an optical fiber composite wire core and three groups of insulating wire cores, and the wrapping tape layer is externally wrapped by a first reinforcing layer, a shielding layer, a second reinforcing layer and an outer sheath layer in sequentially from the inside out; a filling agent is arranged among the optical fiber composite wire core, the three groups of insulating wire cores and the wrapping tape layer; and the three groups of insulating wire cores comprise oxygen-free copper conductors respectively, and the outer sides of the oxygen-free copper conductors are wrapped by first insulating layers; and the outer side of the optical fiber composite wire core is wrapped by a second insulating layer. The composite anti-interference optical fiber communication control cable provided by the utility model is strong in anti-electromagnetic interference.
Description
Technical field
The utility model relates to compound anti-interference optical fiber communication control cables.
Background technology
Optical fiber has following advantage:
1) bandwidth, message capacity is large.The available bandwidth of optical fiber is about 50000GHz, the 1.7Gb/s optical fiber telecommunications system come into operation in 1987, and a pair of optical fiber can transmit No. 24192 phones simultaneously, and the 2.4Gb/s system can be transmitted 30000 multiplex telephonies simultaneously.Bandwidth, be of great significance for the various wideband information tools of transmission, otherwise, can't meet the needs that following broadband integrated services digital network (B-ISDN) develops.
2) loss is low, and repeater span is long.The loss of current practical silica fiber can be lower than 0.2dB/km, and all lower than the loss of other any transmission medium, if adopt non-Silica utmost point low loss fiber in the future, its theory analysis loss can drop to 10-9dB/km.Because the loss of optical fiber is low, so can realize that repeater span is long, the maximum repeater span of the optical fiber telecommunications system be comprised of silica fiber can reach km more than 200, the communication system formed by non-Silica utmost point low loss fiber, its maximum repeater span can reach thousands of even tens thousand of kms, and this has special significance for the cost that reduces submarine communication, raising reliability and stability.
3) anti-electromagnetic interference.Optical fiber is insulating material, it is not subject to the interference of natural thunder and lightning interference, ionospheric variation and Sunspot Activities, be not subject to the interference of the industrial electrical equipments such as electric railway electric wire and high-tension apparatus yet, also available it parallel with high voltage transmission line set up or with the compound formation composite optical cable of control cables.At present the traditional cable message capacity is little, loss is large, a little less than anti-electromagnetic interference.
The utility model content
The purpose of this utility model is to provide a kind of compound anti-interference optical fiber communication control cables, and its anti-electromagnetic interference is strong.
For achieving the above object, the technical solution of the utility model is a kind of compound anti-interference optical fiber communication control cables of design, comprise wrapped belt, be provided with the compound core of optical fiber and three groups of insulated wire cores in wrapped belt, described wrapped belt is enclosed with the first reinforced layer, screen, the second reinforced layer and external sheath layer outward from inside to outside successively; Be provided with filler between the compound core of described optical fiber, three groups of insulated wire cores and wrapped belt; Described three groups of insulated wire cores comprise respectively the oxygen-free copper conductor, at described oxygen-free copper conductor outside parcel the first insulating barrier; At the compound core of described optical fiber outside parcel the second insulating barrier.
Preferably, the aluminium foil that described screen is thickness 0.06mm.
Preferably, the aluminium foil that described screen is thickness 0.07mm.
Advantage of the present utility model and beneficial effect are: a kind of compound anti-interference optical fiber communication control cables is provided, and its anti-electromagnetic interference is strong.
