Technical field
The present invention relates to cable jacket technical fields, and in particular to it is a kind of for optical cable around packet mode electromagnetic shielding film.
Background technology
Optical cable being widely used in existing communication network is general.In radio art, many occasions are required for using
Optical cable transmits signal, and still, optical cable can have an impact the signal transmitted, when by outside electromagnetic interference so must
Electromagnetic shielding processing must be carried out to optical cable.
In the prior art, typically outside optical cable there is the plastic sheath of effectiveness to be protected, is moulded
Material sheath installs additional when cable runs are constructed, i.e., plastic protecting casing is first embedded in underground, then again inside protecting pipe
Cable of giving out light is worn, and at connection jaws, due to wiring and the needs of associated maintenance, electromagnetic shielding sheath at this time often needs to be opened
Come to maintain easily, therefore the plastic sheath that pre-production is completed necessarily is not suitable for, in addition, the outside cladding imprecision of optical cable is then
It can lead to electromagnetic interference, influence the stability of optical cable transmission signal.
Invention content
For the problems of the prior art, it is electromagnetically shielded around packet mode for optical cable the purpose of the present invention is to provide a kind of
Film, it is ensured that while effectiveness of the optical cable at connection jaws, facilitate the maintenance at optical cable connection jaws.
