First embodiment
Referring to Fig. 1, present embodiments providing a kind of water-drop-shaped optical cable 10, it is smaller by windage, and icing area is small, it is ensured that
Water-drop-shaped optical cable 10 will not be torn damage in bad weather, and be avoided that the rotation of water-drop-shaped optical cable 10 is resonated, it is ensured that water
Drip the stable transmission of the signal of shape optical cable 10.Wherein, the cross section of water-drop-shaped optical cable 10 is in water-drop-shaped, the water-drop-shaped optical cable of water-drop-shaped
10 cause water-drop-shaped optical cable 10 in atrocious weather, and the windage being subject to is smaller, and icing area is also smaller, reduces water droplet
Shape optical cable 10 is significantly rocked because of what wind was produced, and improves the increase that the icing of the surface large area of water-drop-shaped optical cable 10 is caused
The weight of water-drop-shaped optical cable 10, reduces the situation that water-drop-shaped optical cable 10 is pulled off.
The cross section of water-drop-shaped optical cable 10 has big end and small end, and the middle part held greatly is outwardly and so that big away from small end
The outline at end is shaped form, and away from holding greatly, outwardly and so that the outline of small end is shaped form at the middle part of small end.At this
In embodiment, the outline held greatly is circular arc, and the outline of small end is circular arc, and the diameter of end circular arc greatly is more than small end circular arc
Diameter.In addition, the arrogant end of the width of cross section is tapered into small end, and the smooth big end of connection and small end, to be formed
Water-drop-shaped.It should be appreciated that in other embodiments, the outline of big end and small end can also be fold-line-shaped；Or, big end or small
It is fold-line-shaped to hold the outline of one of them, and another is shaped form.
In addition, water-drop-shaped optical cable 10 includes sheath 100, cable core 200 and Suspension 300, cable core 200 and Suspension 300 are equal
