Description
Technical field
This utility model is related to a kind of armored soft optical cable, belongs to technical field of optical fiber communication.
Background technology
, due to having the excellent performance that circumnutates, outer application is also more and more extensive indoors for armored soft optical cable.Existing armour
The structure of dress flexible optical cable is mainly made up of the optical fiber positioned at optical cable center and protection shell, and protection shell mainly includes the virtue of tension
Synthetic fibre layer and measuring body steel pipe, its effect be optical cable is pressurized or extended state under internal optical fiber is carried out being protected from optical fiber
Impaired.Although it can carry out effective protection, armored soft optical cable warp when optical cable is in pressurized or stretching to internal optical fiber
Often need winding or bend, external protection can extrude to optical fiber surface unavoidably in winding BENDING PROCESS, causes optical fiber table
Face scratches or weares and teares, and makes signal relaxation phenomenon, reduces signal transmission through fiber ability.
Utility model content
For the problems referred to above, this utility model provides a kind of armored soft optical cable, its object is to：In optical fiber surface setting
