It is installed under environment, improves cable strength.
Water blocking layer 25 is additionally provided between the metal protection layer 23 and tightly packaged fiber 1.The infiltration of moisture can be prevented, the company of raising
Wiring under circumstances being capable of normal communication work.
The tightly packaged fiber 1 includes fibre core 11, primary coating layer 12, rubber insulation 13, rubber insulation from inside to outside
13 by primary coating layer 12 and 11 hard-pressed bale of fibre core inside it.Using tightly packaged fiber 11 so that optical cable is more soft, easily peelable, property
Can be high, bending radius is small, and machinery and environmental performance are more excellent.
21 cross section of the outer jointing jacket is ellipse, and the outer surface of the outer jointing jacket 21 is arranged with V-shaped groove 211.
It can make independent optical cable while can bear pressure using structure of the ellipse with V-shaped groove, pass through ability relatively good, especially
When needed in narrow space across installation, more easily optical cable connecting line passes through.
The optical fiber connector 3 is LC connectors.Lucent Connector is one kind of optical fiber connector, because apparent size is only
The half of SC/ST/FC connectors is accounted for, therefore belongs to miniature connector type（SFF）One kind.Lucent Connector is widely used in comprehensive
Close wiring system engineering.
The optical fiber connector 3 is SC connectors.SC is relatively common optical fiber connector, on router switch and
Transmission device sidelight interface it is most.SC connectors directly plug, very convenient to use, come the disadvantage is that simply falling out.For
For 100Base-FX, connector is in most cases SC types, and the core of SC connectors is inside connector.
The operation principle of the utility model：Two independent optical cables are integrally formed by dowel, dowel is conducive to two
The separation of independent optical cable, two independent optical cables, which are registered one's residence, is more conducive to the installation of user, and a such as independent optical cable damages another
Independent optical cable can also normal use, the resistance to compression waterproof fireproofing protection against rodents structure in independent optical cable can effectively improve connection line of optic fibre
Installation under a variety of different environment and use can prevent worm, mouse from biting.
After adopting the above technical scheme, the utility model has the beneficial effect that：It is simple in structure, in small space installation side
Just, double optical cables are registered one's residence user-friendly, and resistance to compression, waterproof, fire prevention, insect prevention, protection against rodents can extend connecting line under circumstances
Service life.
