Embodiment

Embodiment 1:

Fig. 1 is asked for an interview in ; The USB optical cable for connection that provides comprises the oversheath 2 that cable core 1 is outer with being positioned at cable core 1, and cable core 1 comprises that six roots of sensation material is the conductor 11 and an optical fiber 12 and an intensive aspect 13 of copper, and six roots of sensation conductor 11 is around 12 arrangements of an optical fiber; Just this optical fiber 12 is positioned at the middle position of six roots of sensation conductor 11; Respectively be coated with insulating barrier 111 outside the conductor 11, in the present embodiment, the diameter of conductor 1 is 0.25 ㎜; Insulating barrier 111 adopts the low smoke and zero halogen polyethylene, and thickness is 0.25 ㎜.Optical fiber 12 is positioned at the protective sleeve 121 of being filled the post of (taking on) by nylon, makes optical fiber 12 constitute tight tube fibers, so that connect, and optical fiber 12 is monomode fiber, and monomode fiber such as G652, G653, G655, G656 or G657, present embodiment are G653.Intensive aspect 13 uses aramid yarn, and the intensive aspect of being filled the post of by this aramid yarn 13 surrounds conductor 11 and optical fiber 12.The mode of covering is crowded covers oversheath 2 to squeeze outside intensive aspect 13, and the material of oversheath 2 is the low smoke and zero halogen polyethylene.Preferably, the colour planning of the insulating barrier 111 that six roots of sensation conductor 11 is outer be different, so that differentiation.The external diameter of the USB optical cable for connection that present embodiment obtains is 2.8 ㎜.
