Abstract
The invention relates to the technical field of indoor/outdoor communication optical cable manufacture, and especially relates to a micro-beam-tube easily-branched optical cable. The optical cable comprises a plurality of fibers. Each fiber is externally coated with a 0.6-1.5 mm oil- scraping micro sleeve tube. The oil- scraping micro sleeve tube is internally filled with fiber paste. The oil- scraping micro sleeve tubes are stranded around a nonmetal center reinforcement member. The oil- scraping micro sleeve tubes are externally wrapped with aramid, a water-blocking belt, a composite aluminium-plastics tape and an outer sheath in sequence. The surface of the outer sheath is provided with arc-shaped grooves, wherein the arc-shaped grooves are located right above tearing ropes. The optical cable utilizes the one-core-one-tube oil- scraping micro sleeve tubes which are stranded around the FRP center reinforcement member, so that the optical cable is low in production cost, easy to separate, and helps to solve the problem of vertical dripping of the conventional oil-filling loose tube, and can be wired indoor vertically. The surface of the outer sheath of the cable is provided with the arc-shaped grooves, thereby facilitating the airflow to pass, not depositing dirt such as dusts and seeds and the like, and even eggs cannot live on the cable; when the cable is branched, the outer sheath is directly torn open and thus the demand for multi-line branches is met.
Description
Technical field
The present invention relates to communication indoor and outdoor fiber optic cable manufacture technical field, be specifically related to the easily branched type optical cable of a kind of microbeam pipe.
Background technology
Traditional easily branched optical cable is generally directly to make tight tube fiber coated with the tight cover material of high bond strength outside single mode or multimode optical fiber; then adopt high-intensity aramid fiber as reinforcing element; and extrude one deck PVC inner sheath (or LSZH inner sheath) in outside and make the sub-cable in unit; the sub-cable of many root units is after central reinforce member is stranded; add aramid yarn armouring; then wrapped band, then adopt PVC or LSZH to make as oversheath.
Growing along with the communication technology, communication network topology structure presents diversified trend, especially " integration of three networks " is formally since national key cities bring into operation, many matchmakers such as Internet data communication, video request program, videophone, video conference suspend business, and business is rapid to be expanded, broadband, high speed to physical network are had higher requirement, make to be widely used in Fiber to the home and the transmission network of fiber to the desk become optimal transmission mode, this just requires Access Network optical cable to have advantages of flexible route, branch etc.
Current easily branched optical cable on the market, owing to having used in a large number high strength aramid fiber as reinforcement, increases the cost of unit length optical cable greatly.Tightly overlap in addition subelement manufacture craft more complicated, and finished product cable footpath is larger, takies certain installing space.
