The application be on 07 15th, 2016, application No. is 201610567368.5, entitled " butterfly the applying date
The divisional application of optical cable ".
Technical field
The present invention relates to optical fiber cable production field, in particular to a kind of butterfly optical cable.
Background technique
Butterfly optical cable is a kind of novel user access optical cable, according to application environment and laid condition difference, rationally designs light
Cable structure and every technical parameter, the characteristics of having gathered indoor flexible optical cable and self-support cable.Butterfly optical cable is FTTX network solution
Certainly best alternate product plays its unique effect in setting up the networks such as intelligent Building, digital cells, campus network, local area network.
Existing butterfly optical cable: 1) using fillet square, racetrack, the design of 8 fonts, during wiring frequent occurrence
Twisted phenomena, and because butterfly optical cable is locking structure, stress is generated to optical fiber, fiber attenuation coefficient is caused to increase, reducing optical fiber makes
Use the service life.2) there was only one layer of very thin plastics between butterfly optical cable bottom portion of groove and optical fiber, be easy to happen infiltration, optical fiber is caused to send out
Raw hydrogen loss, causes fiber attenuation coefficient to increase, and reduces optical fiber service life.3) in building wiring, construction personnel is to butterfly
When shape optical cable is removed, because optical cable is locking structure, optical fiber mechanical damage frequent occurrence.Optical cable is easily distorted, and leads to optical fiber
It is impaired, or even in corner, cable structure separation.4) protect the ability of optical fiber weak.5) mushroom mildew is easy to happen in optical cable groove,
Corrode sheath and optical cable, and not easy-clear.

A possibility that generating mould and seeping water is effectively reduced with groove, improves the ability of protection optical fiber.So that existing
Butterfly optical cable the service life it is poor, be easy that infiltration, bending property is poor, the weak defect of optical fibre capacity is protected to be addressed.
The cavity 6 is ellipse, and elliptical length direction is parallel to the extending direction for directly stretching block 112.Cavity 6 is set
For ellipse, elliptical length direction is parallel to the extending direction for directly stretching block 112, and 6 thickness as outside of cavity is smaller, convenient for tearing
It opens, and is more conducive to tear exoperidium using pointed object insertion extension end.Specific production process can be above cavity
Insulating layer epidermis be equipped with color marking, it is indicated that its position torn.
The soft material is ointment.The ointment includes silicone oil.Using in ointment and ointment include silicone oil, damping property
Can, waterproof effect more preferably, and it is smaller in the curved resistance of fiber containment chamber 5 to optical fiber 2.Two are equipped in the fiber containment chamber 5
The optical fiber 2 of root or two or more.The insulating layer 3 in 6 outside of cavity protrudes outward forms bulge area 7.The bulge area 7
With a thickness of 0.5mm.
Embodiment two: the invention also discloses a kind of butterfly optical cable, the insulating layer 3 in 6 outside of cavity protrudes outward
Form bulge area 7.The bulge area 7 with a thickness of 1.5mm.The insulating layer 3 that 6 outside of cavity is arranged protrudes outward forms bulge
Area 7, and bulge area 7 with a thickness of 0.5mm-1.5mm;The bulge area 7 of protrusion will not gather water droplet, and be conducive to waving for moisture
Hair, it is difficult to generate mould or gather dirt, reduce the influence of moisture deeply generated to optical fiber, the bulge area 7 of protrusion is convenient for
Personnel using when find out fiber containment chamber 5, tear insulating layer 3 using sharp instrument, take out optical fiber.
When the embodiment of the present invention is implemented, bulge area is found out by implementation personnel, tears ellipse using sharp weapon (including nail)
Insulating layer on the outside of cavity finds out extension end at the both ends of elliptical cavity, uses above and below sharp weapon insertion extension end two
Insulating layer exoperidium is firmly torn simultaneously in side outward, extracts optical fiber therein out, carries out the installation etc. of optical fiber.
