Abstract
The utility model relates to an air duct / outdoor full-dry optical cable, which comprises a loose tube fiber, aromatic polyamide yarn which is covered outside and expands when encounters water, and an outer sheath made of low smoke halogen-free flame retardant materials. When installed in a local area network, the utility model can enter rooms from the outside directly or enter an air duct environment without switching points. The utility model has the advantages of the integrity of optical cables, few fault points and low installation cost.
Description
Technical field
The utility model relates to a kind of communication network optical cable, especially outdoor, indoor optical cable that can be general.
Background technology
Existing LAN (Local Area Network) generally adopts different optical cables with its outdoor section of optical cable and indoor section, and outdoor optical cable will be transferred to it on the inside cable after drawing in buildings, has caused many optical cable transit points, just may increase the trouble spot, also improves installation cost simultaneously.
Summary of the invention
For overcome existing LAN (Local Area Network) with optical cable in the deficiency that exists aspect the connection, the utility model provides a kind of ventiduct/outdoor dry type optical cable, can be directly during installation from outdoor to indoor or enter the ventiduct environment, do not have transit point, keep the globality of optical cable.
Ventiduct provided by the utility model/outdoor dry type optical cable comprises cable core (6) and oversheath (5), cable core (6) is made of optical fiber (1) and loose sleeve pipe (3) thereof, fill water-swellable powder (2) in the pine sleeve pipe (3), coat water-swellable aramid yarn (4) between cable core (6) and the oversheath (5).
The another kind of technical scheme of ventiduct provided by the utility model/outdoor dry type optical cable comprises cable core (6) and oversheath (5), cable core (6) by central reinforce member (7) and the include water-swellable powder (8) and the outer water-swellable that coats of loose sleeve pipe (3) of filling in the space between optical fiber (1) and the loose sleeve pipe (3) of water-swellable powder (2), the loose sleeve pipe (3) that are provided with on every side prick yarn (9) formation, coating water-swellable aramid yarn (4) between cable core (6) and the oversheath (5).
The beneficial effects of the utility model be can be directly when installing from outdoor to indoor or enter the ventiduct environment, do not have transit point, keep the globality of optical cable, reduce the fault point, reduce installation cost.
