Abstract
The utility model discloses an optical cable consisting of a optical cable protecting shell and a flexible metal sleeve optical fiber patch cord consisting of a plug connector. The utility model is characterized in that a fiber-core optical cable, which goes through an optical fiber core insert (4) from a tail seat (5) of the optical fiber core insert is wrapped with a flexible metal tube wrapping layer, which extends to the tail seat of the fiber core insert, and is connected with an axial spring (6) arranged at the end; moreover, the optical cable is connected with the plug connector at the end to form a fully closed integrated structure without any clearance. As the utility model uses the flexible metal tube, which wholly wraps the optical fiber, the defect that a bare optical fiber clearance is left between the flexible metal tube and the tail seat of the optical fiber core insert with the prior art is avoided, the problem that the optical fiber is liable to bend and cause increased loss during the course of the patch cord procession, installation and use is settled, and the optical fiber is always protected by the flexible metal tube either in the course of a connecting device or in other application environments of construction and installation.
Description
Technical field
The utility model relates to a kind of being widely used in various optical fibre devices and the various optical fiber telecommunications system, the coupling arrangement of signal transmission such as transmission data, voice, image.The optical patchcord that particularly is widely used in field environment, family, working environment, fiber temperature sensing system engineering etc.
Background technology
The joints of optical fibre (claiming wire jumper again) are meant that the light two ends all load onto connector plug, are used for realizing that light path flexibly connects.One end is equipped with plug and then is called tail optical fiber.The loss characteristic of optical fiber is one of greatest factor of decision optical-fiber network transmission range, transmission stability and reliability.The generation reason of fiber transmission attenuation is many-sided, in the construction and maintenance of Networks of Fiber Communications, it is worth noting that optical fiber causes the reason of loss and how to reduce these losses in using most.The loss that optical fiber causes in using mainly contains connecting loss (inherent loss of optical fiber, splice loss, splice attenuation and active joint loss) and non-connecting loss (loss that bending loss and other construction factor and applied environment are caused) two classes.The non-connecting loss that optical fiber causes in using mainly contains the loss that bending loss and other construction factor and applied environment cause.The radiation loss that bending causes is to be subjected to very big bending when optical fiber, and when bending radius and its core diameter had comparability, its transport property can change.A large amount of guided modeses are converted to radiation mode, no longer continue transmission, and foot enter the coated layer of covering or covering absorbs, thereby cause the added losses of optical fiber.The bending loss of optical fiber has two types of macrobend loss and microbend losss.1. the added losses that cause of the bending of manying (macrobend) that the radius-of-curvature of macrobending loss optical fiber is bigger than fibre diameter, main cause has: route turn and lay in bending; The bending that the various reservations of optical fiber cable cause (reserving circle, various) by curved, natural torsion; In the connector box dish of optical fiber stay, the coiling etc. of tail optical fiber in machine room and the equipment.2. the microbending loss fiber axis produces the added losses that the bending (little curved) of μ m level causes, main cause has: during optical fiber cabling, small irregular of area supported causes that the each several part unbalanced stress is even and randomness that form is little curved; The little of the rough formation of interphase of fibre core and covering bends; During fiber cable laying, everywhere tension force inhomogeneous and form little curved; The wall pressure that optical fiber is subjected to is inhomogeneous.
In recent years, information handling system development requires high to quick, convenient, the security and the reliability of information transmission rapidly.Under relative rugged environment, because traditional optical patchcord can not solve tension, resistance to compression, protection against rodents, antitorque, indeformable problem, characteristics such as high compressive strength, tensile strength height, mouse bite preventing, diameter are little, soft pliable song have appearred, can be used in various rugged surroundings, the metal armouring optical patchcord that combines by the connector of metal armouring optical cable and various models.The metal armouring optical patchcord is to add a small stainless-steel tube and a flame-proof PVC bag shoe stainless steel braided wires at fibre core to protect.Because the flexible metal flexible pipe of prior art and fiber stub tailstock leave one section gap of carrying out of bag, the optical fiber that exposes in the gap leads or involves in the position of use at dish and causes the optical fiber added losses often.The existence of this backlash freedom degree has strengthened optical fiber extruding flexural deformation, fold distortion, and the little curved probability of randomness can cause the instability of signal transmission, thereby can not thoroughly protect the normal transmission of fiber-optic signal.Can not solve fully in the wire jumper process, easily produce optical fiber micro-bending in the installation process, in the use and the problem that causes loss to increase.Not only cause the waste of production, and influence the stability and the transmission speed of system signal transmission.
Summary of the invention
Can not avoid the little curved added losses that cause optical fiber of randomness in order to overcome existing metal armouring wire jumper; not exclusively protect the deficiency of optical fiber cable; the utility model purpose provides and a kind ofly can make signal transmission more reliable, more the flexible metal casing fiber optic patch cord of stable transfer signal.
The technical scheme that its technical matters that solves the utility model adopts is: the flexible metal casing fiber optic patch cord body that a kind of optical cable of being made up of the optical fiber cable protecting sheathing and pin connector are formed; it is characterized in that; the doped core optical fiber line bag shoe that penetrates fiber stub from fiber stub tailstock end has one deck to be connected to the flexible metal flexible pipe covering of fiber stub tailstock always; and join with the axle spring that is equipped with the termination, connect into gapless totally-enclosed integrative-structure with the pin connector of termination.
The utility model has following beneficial effect than prior art.
Because adopting, the utility model is communicated with the flexible metal flexible pipe that bag is carried out optical fiber cable completely, thoroughly avoided prior art flexible metal flexible pipe and fiber stub tailstock to leave the deficiency in one section nuditing fiber gap, solved in the wire jumper process, easily produced the problem that optical fiber micro-bending causes loss to increase in the installation process, in the use.Make optical fiber no matter in the coupling arrangement process of manufacture, still in other construction connection applied environment, be in the protection of flexible metal flexible pipe all the time, can not cause optical fiber to be subjected to very big bending.The extruding bending of nuditing fiber backlash freedom space, fold distortion have fundamentally been eliminated, the little curved probability of randomness.Can avoid optical fiber to lead at dish, tractive easily causes the defective and because the inhomogeneous loss increase that causes optical fiber micro-bending to produce of deformation of optical fiber added losses.Thoroughly protect the normal transmission of fiber-optic signal.Make it have extremely low insertion loss and stable reflection loss, guarantee that under various environment, service condition signal is normal, transmission signals is more stable, transmission speed is more reliable.
