Large diameter core multimode optical fiber |
| abstract |
The present specification describes a multimode optical fiber produced in an improved manner that reduces manufacturing costs. These methods may be more efficient in terms of power loss. In one embodiment, the improved design has a large diameter core of pure silica produced by a rod-in-tube system. In this embodiment, a down-doped cladding is generated by depositing fluorine-doped silica inside the silica starting tube using isothermal radio frequency plasma deposition. The silica core is inserted and the starting tube is collapsed. The silica starting tube is removed and the optical fiber is drawn from a silica rod coated with fluorine-doped glass.
