Abstract

An optical cable and an optical cable assembly having the same are provided. The optical cable includes a plurality of optical fibers each of which includes a core, a clad arranged on an outside of the core, and a coating layer arranged on an outside of the clad; a substantially transparent sheath in which the plurality of optical fibers are arranged; and a substantially transparent filler configured to fill a space between the sheath and the plurality of optical fibers.

First claim

What is claimed is:

1 . An optical cable comprising:
a plurality of optical fibers each of which includes a core, a clad arranged on an outside of the core, and a coating layer arranged on an outside of the clad; a substantially transparent sheath in which the plurality of optical fibers are arranged; and a substantially transparent filler configured to fill a space between the sheath and the plurality of optical fibers.

2 . The optical cable as claimed in claim 1 , further comprising a tensile line inserted into the filler.

3 . The optical cable as claimed in claim 2 , wherein the tensile line is formed to be penetrated by the light.

4 . An optical cable assembly comprising:
first and second photoelectric converters; and an optical cable configured to connect the first and second photoelectric converters to each other, wherein the optical cable includes: a plurality of optical fibers each of which includes a core, a clad arranged on an outside of the core, and a coating layer arranged on an outside of the clad; a sheath in which the plurality of optical fibers are arranged to be penetrated by light; and a filler configured to fill a space between the sheath and the plurality of optical fibers to be penetrated by the light.

5 . The optical cable assembly as claimed in claim 4 , wherein each of the first and second photoelectric converters comprises:
a circuit board; a shield can configured to surround the circuit board; and a housing in which the shield can is disposed.

6 . The optical cable assembly as claimed in claim 5 , wherein the housing is formed to be penetrated by the light.

7 . The optical cable assembly as claimed in claim 5 , wherein a plug that projects from one end of the housing to outside is formed to extend from the shield can.

8 . The optical cable assembly as claimed in claim 5 , wherein a trumpet-shaped guide, of which the width is gradually narrowed toward an inside of the housing, is formed on the other end of the housing.

9 . The optical cable assembly as claimed in claim 8 , wherein an inner circumferential surface of the trumpet-shaped guide is a curved surface.

10 . The optical cable assembly as claimed in claim 5 , wherein the circuit board is mounted with:
a lens system configured to connect the optical cable and the circuit board to each other; an optical element system configured to emit and/or absorb light; and an optical drive IC configured to operate using an optical signal.

11 . The optical cable assembly as claimed in claim 10 , wherein the plurality of optical fibers are branched from opposite ends of the optical cable inserted into the first and second photoelectric converters.

12 . The optical cable assembly as claimed in claim 11 , wherein the plurality of optical fibers are fixed to lenses of the lens system.

13 . The optical cable assembly as claimed in claim 12 , wherein the lens system is disposed between the optical cable and the optical element system.

14 . The optical cable assembly as claimed in claim 10 , wherein each of the first and second photoelectric converters further comprises:
a first support disposed in the shield can to support the circuit board; and a second support disposed outside the shield can to guide the optical cable into the shield can.

15 . The optical cable assembly as claimed in claim 14 , wherein the first support comprises left and right support pieces, and
surfaces of the left and right support pieces in the shield can, the surfaces facing each other, gradually go away from each other moving in a direction in which the optical cable is to be inserted into the lens system.

16 . The optical cable assembly as claimed in claim 14 , wherein the second support is formed of a transparent material.

17 . The optical cable assembly as claimed in claim 5 , wherein a vent hole is formed on the housing to dissipate heat generated from the optical drive IC.

18 . The optical cable assembly as claimed in claim 8 , wherein anti-skid projections are formed on an outer surface of the housing.
