Description
Technical Field
The utility model relates to an optical cable lays the equipment field, especially relates to a preparation optical cable becomes end and uses traction optical fiber device.
Background
Optical fiber cables are an essential transmission medium for optical communication systems. The common optical cable can be divided into various types such as a layer stranded type, a skeleton type and a central beam tube type according to the structure division of the optical cable, and the internal structures of various optical cables comprise a polyethylene outer protective layer, an aluminum protective layer, a loose tube, optical fibers and the like. The optical fiber has the physical characteristics of large radial tension force, small transverse force, brittleness, easy breaking and the like, and therefore, the optical fiber is placed in the loose tube in the optical cable. The loose tube has a plurality of optical fibers threaded therethrough, the optical fibers being loosely distributed within the loose tube to prevent the optical fibers from being compressed within the cable. The optical fiber consists of a fiber core, a cladding, a coating layer and a plastic coating layer, in order to prevent a plurality of optical fibers from rubbing with each other to damage the optical fibers in the manufacturing process of the optical cable, and simultaneously, in order to prevent the coating layer and the plastic coating layer of the optical fibers from being oxidized or damped in the air to cause the deterioration of the transmission performance of the optical fibers and influence the service life of the optical fibers in the using process of the optical fibers, the surface of the optical fibers in the loose sleeve is coated with factice.
The ointment coated on the surface of the optical fiber (referred to as optical fiber ointment for short) has the function of water resistance, can play a role of a pad for the optical fiber in the loose tube, and can buffer the influence of mechanical forces such as vibration, impact, bending and the like on the optical fiber. The optical fiber ointment is a viscous semisolid substance and consists of materials such as a gelling agent, an antioxidant, base oil and other additives. Wherein the gelling agent accounts for 5-20% of the mass of the optical fiber ointment and is usually composed of fatty acid salt, paraffin, various high molecular polymers and the like; the base oil accounts for 70-90% of the ointment by weight, and mineral oil, synthetic oil or silicon oil and the like are usually adopted. Therefore, the optical fiber ointment has certain viscosity and oiliness, and the ointment on the surface of the optical fiber needs to be cleaned up during construction, so that the phenomenon that the ointment influences the placement of the optical fiber in the optical cable splice box, the cleanliness of the end face of the manufactured optical fiber during optical fiber fusion and the loss value of the optical fiber splice is avoided.
In the construction process of communication engineering, when the end of an optical cable terminal is manufactured, a polyethylene protective layer and an inner aluminum protective layer of the optical cable are firstly stripped, after a loose tube is exposed, the loose tube is carefully removed, the optical fiber is separated from each protective layer outside the optical fiber, and then ointment on the surface of the optical fiber is removed. The cleaning method of the optical fiber ointment is to wipe off a large amount of ointment on the surface of the optical fiber by using toilet paper or tissue paper, and the ointment on the surface of the optical fiber is cleaned as much as possible by wiping for many times. Since the optical fiber is brittle and easily broken, special attention needs to be paid to the safety of the optical fiber during the process of wiping the ointment on the surface of the optical fiber, and the wiping process can be performed only along the radial direction of the optical fiber. In the process of wiping the optical fiber ointment, the surface of the optical fiber is rubbed by the tissue paper and the absorbent cotton, so that static electricity is generated on the optical fiber; in order to prevent the optical fiber from being broken off from various protective layers, a PVC plastic hose with the inner diameter/outer diameter of 5mm/6mm is sleeved on the outer surface of the cleaned optical fiber. When an optical cable terminating end is manufactured on an optical fiber distribution frame (ODF) in a communication machine room, a wiped optical fiber needs to penetrate into a PVC (polyvinyl chloride) hose with the length of more than 1 meter, a bare long-section optical fiber is relatively soft, and the optical fiber is easily adhered to the inner wall of the PVC plastic pipe due to the influence of static electricity on the surface of the optical fiber, so that a constructor can hardly penetrate the bare optical fiber into the PVC plastic pipe; because the inner diameter of the PVC plastic pipe is small, the bare optical fiber cannot pass through the PVC plastic pipe after being bound, the process that the bare optical fiber penetrates into the PVC plastic pipe is a time-consuming and labor-consuming process in the process of manufacturing the finished end of the optical cable, a simple and convenient operation tool is urgently needed to be researched and developed, the operation problem of construction personnel is solved, and the work efficiency is improved.
