Background technique
Optical cable is very widely used in existing communication network.In radio art, many occasions require 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 there is outside optical cable the plastic sheath of effectiveness to be protected, is moulded
Material sheath is installed additional in cable runs construction, 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 will lead to electromagnetic interference, influence the stability of optical cable transmission signal.
Summary of the invention
For the problems of the prior art, the purpose of the present invention is to provide a kind of being electromagnetically shielded around packet mode for optical cable
Film, it is ensured that while effectiveness of the optical cable at connection jaws, facilitate the maintenance at optical cable connection jaws.
