For reaching this purpose, this utility model employs the following technical solutions：
A kind of dual-core optical fiber jumper, including wire jumper body, the two ends of described wire jumper body are provided with union joint, and union joint is used
In connecting adapter, to realize the connection of light path, described wire jumper body includes two heart yearns and is coated on two described heart yearns
Outside protective case；Every described heart yearn includes cable core, and the outside of described cable core is coated with big envelope, the outside bag of described big envelope
It is covered with insulating barrier, the outside of described insulating barrier is coated with spongy layer；It is wear-resisting that described protective case includes that ecto-entad sets gradually
Layer, waterproof layer, elastic layer.
Wherein, described wire jumper body and the junction of described union joint are arranged with adapter sleeve.
Wherein, the outside of every described heart yearn is all arranged with ring spring, and described ring spring is arranged at described spongy layer
And described wearing layer between, the two ends of described ring spring are individually fixed in two described union joints.
Wherein, described insulating barrier is chlorinated polyethylene layer.
Wherein, it is additionally provided with flame-retardant layer between described wearing layer and described waterproof layer.
Wherein, the thickness of described protective case is 1～10 μm.
Compared with prior art, the beneficial effects of the utility model are：A kind of dual-core optical fiber jumper of the present utility model, bag
Include wire jumper body, the two ends of described wire jumper body are provided with union joint, and described wire jumper body includes two heart yearns and is coated on
The protective case in the outside of two described heart yearns；Every described heart yearn includes cable core, and the outside of described cable core is coated with big envelope, described
The outside of big envelope is coated with insulating barrier, and the outside of described insulating barrier is coated with spongy layer；Described protective case include ecto-entad according to
The wearing layer of secondary setting, waterproof layer, elastic layer；Two heart yearns are capable of double fine transmission, the outside cladding of every cable core exhausted
Edge layer makes transmission between two heart yearns will not interfere；The design of wearing layer, waterproof layer, elastic layer in protective case, makes double
Core fibre wire jumper is more wear-resisting when migrating in use, be wound around, bending, good water-proof effect, long service life.
Brief description
