Abstract
The invention provides a communication optical cable and relates to the field of communication facilities. The communication optical cable comprises a plurality of optical fiber units which are annularly arranged on the periphery of a reinforcing ring, limiting grooves are uniformly formed in the outer circumference of the reinforcing ring, the optical fiber units are arranged in the limiting grooves, the optical fiber units are wrapped in a framework layer, aluminum-clad steel stranded wires are annularly arranged on the periphery of the framework layer, a buffer layer is arranged on the peripheries of the aluminum-clad steel stranded wires, the buffer layer is wrapped in a layer of reinforcing wires, the reinforcing wires are wrapped in a waterproof layer, and the waterproof layer is wrapped in an outer sheath. The buffer layer is an integral plastic layer, and bubbles are formed in the plastic layer. An obliquely-braided supporting framework is arranged in the framework layer. The reinforcing ring is arranged in the communication optical cable so that the communication optical cable can have definite strength; the limiting grooves are formed in the wall of the outer circumference of the reinforcing ring and are used for not only supporting the optical fiber units but also limiting the optical fiber units; the aluminum-clad steel stranded wires are arranged on the periphery of the framework layer, the reinforcing wires are arranged on the peripheries of the aluminum-clad steel stranded wires, and therefore the strength is high, mutual interference is small, the optical fiber units can be stranded tightly, and optical fibers are protected effectively.
Description
Technical field
The present invention relates to communications facility field, particularly relate to a kind of communications optical cable.
Background technology
The cable heart that communications optical cable is made up of some (core) optical fiber (generally from a few core to several thousand cores) and outer jacket formed.Optical fiber is compared with traditional symmetrical copper loop and coaxial copper loop, and its transmission capacity is much bigger; Attenuation is few; Transmission range is long; Volume is little; Lightweight; Without electromagnetic interference (EMI); Cost is low, is the most promising current communications media.It is just being widely used for, on the Signal transmissions of all departments such as telecommunications, electric power, broadcast, progressively becoming the main body of future communications network.Structurally main with the cable difference of optical cable is that optical cable must have stiffener to go to bear extraneous mechanical load, to protect optical fiber from the impact of various outer mechanical force.Optical cable, in laid processes, usually will stretch, is wound around or extrudes, and easily makes light unit impaired, impact transmission.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The object of the present invention is to provide a kind of communications optical cable, to solve the problems of the technologies described above.
Technical matters to be solved by this invention realizes by the following technical solutions:
A kind of communications optical cable, comprise some fiber units, it is characterized in that: described some fiber units are established around ring stiffener peripheral ring, on described ring stiffener excircle, uniform ring is provided with limited impression, described fiber unit is placed in limited impression, one deck casing play is wrapped up outside described fiber unit, casing play has been peripherally installed with aluminum-cladding stranded wire, cushion is arranged with outside described aluminum-cladding stranded wire, one deck line feeder is wrapped up outside cushion, line feeder periphery is coated with water-resisting layer, wraps up oversheath outside water-resisting layer; Described cushion is overall plastic layer, and plastic layer inside is provided with bubble; Described casing play inside is provided with the support frame of braiding, and the skeleton tilting to interweave has certain intensity on the one hand, and also have some elasticity on the other hand, casing play plays the effect making and cushion external impact in the middle layer of communications optical cable.
Described fiber unit comprises multifiber and Loose tube, and many stranded optical fiber are enclosed in together by described Loose tube, are filled with fine cream in described Loose tube.
The invention has the beneficial effects as follows:
The invention provides a kind of communications optical cable; in this communications optical cable, there is ring stiffener, optical cable can be made to have certain intensity, ring stiffener outer circle wall is provided with limited impression; while supporting fiber unit; also position-limiting action is played to fiber unit, outside casing play, be arranged with aluminum-cladding stranded wire, outside aluminum-cladding stranded wire, be arranged with line feeder; intensity is high; mutual interference is little, energy closing lay fiber unit, available protecting optical fiber.
