As a further improvement on the present invention, described thin micro tube at least two and mutually stranded.
The invention has the beneficial effects as follows: by such scheme, wrapped up by thermoplastics flame retarding low-smoke halogen-free polyolefin sheath
Many colored optical fibers, are effectively increased the core number of optical fiber.
Accompanying drawing explanation
Fig. 1 is that a kind of dry type of the present invention blocks water the schematic diagram of easy stripping multicore microbeam pipe series optical cable.
Detailed description of the invention
The present invention is further described for explanation and detailed description of the invention below in conjunction with the accompanying drawings.
The easy stripping multicore microbeam pipe series optical cable as it is shown in figure 1, a kind of dry type blocks water, including thin micro tube 1, described thin-walled
Being provided with at least two colored optical fibers 2 and a water blocking yarn 3 in micro-pipe 1, described thin micro tube 1 gathers for thermoplastics flame retarding low smoke and zero halogen
Alkene sheath.
As it is shown in figure 1, described colored optical fiber 2 is the coloured optical fiber of outer surface.
As it is shown in figure 1, the dry type water blocking yarn that described water blocking yarn 3 is low line density.
As it is shown in figure 1, described colored optical fiber 2 has 12 or 32.
As it is shown in figure 1, the thickness of described thin micro tube 1 is 0.15 millimeter.
As it is shown in figure 1, described thin micro tube 1 at least two and mutually stranded.
A kind of dry type that the present invention provides blocks water easy stripping multicore microbeam pipe series optical cable, has that size is little, core number is big
Advantage, is mainly used in the devices interconnect of data center module it can also be used to indoor, indoor and outdoor leading in cable elementary cell.It is special to use
Micro-tube material and water blocking yarn material, coordinate advanced micro-pipe production technology to develop so that this optical cable has body simultaneously
Long-pending little, block water, the advantage of easy stripping.Illustrate as a example by 12 core microbeam pipes below, the easy stripping as it is shown in figure 1, dry type blocks water
Multicore microbeam pipe series optical cable is using 12 colored optical fibers 2 as optical transmission medium, adds the water blocking yarn 3 of a low line density,
The thin micro tube 1 extruding outward one layer of wall thickness about 0.15mm forms.Conventional indoor single core optical cable external diameter is generally 1.6～3.0mm,
The block water external diameter of easy stripping multicore microbeam pipe series optical cable of the dry type of 12 cores can accomplish 1.5mm, and this is on size microminiaturization
Achieve on the most progressive.In thin micro tube 1, place that single line density is little, higher the blocking water of smooth surface, relative intensity
Yarn 3, functions simultaneously as tear rope, makes micro-pipe have water-blocking moistureproof, the feature of easy stripping.Single thin micro tube 1 can place 1-32
The colored optical fiber 2 of core, it is also possible to as elementary cell, made the microbeam pipe of large core number by the many stranded sheaths of thin micro tube 1,
Thus can derive a serial micro-pipe optical cable.
A kind of dry type that the present invention provides blocks water easy stripping multicore microbeam pipe series optical cable, and thin micro tube 1 uses can be thin
The thermoplastics flame retarding low-smoke halogen-free polyolefin protective cover material of wall extrusion (minimum wall thickness (MINI W.) 0.05mm), this material has the physical machine of excellence
Under tool performance, shrinkage factor and good fire resistance.1 to 32 core colored optical fiber 2 can be put in thin micro tube 1, cable outer diameter 3mm with
Under, put a thinner water blocking yarn 3 in thin micro tube 1, dry type blocks water.This water blocking yarn 3 is to have high water absorbency polymer material
Making, line density is less, has the surface of unusual light, directly contact with colored optical fiber 2 in thin micro tube 1 can reduce micro-
The attenuation problem that curved or macrobend causes, relative intensity is higher, owing to thin micro tube 1 wall thickness is the thinnest, typically at 0.05-
Between 0.15mm, this water blocking yarn 3 can serve as tear rope use, is thus provided with the characteristic of easy stripping, it is possible to pinched by two handss
Take tear.Thin micro tube 1 can realize large core number as elementary cell by many thin micro tube 1 stranded sheath strandings
The integrated optical cable of microbeam pipe, relative to traditional indoor multicore wiring optical cable, overall dimensions and the weight of optical cable reduce further.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, it is also possible to make some simple deduction or replace, all should be considered as belonging to the present invention's
Protection domain.
