  • Frozen-fluid fiber guide
    Publication number: 20040146262
    Abstract: A filament guide comprises a support tube having an internal wall defining an axial channel to receive a length of a filament. The axial channel provides containment for a filament closure, surrounding at least a portion of the filament and in contact with at least a portion of the internal wall. The filament closure includes a portion of frozen fluid, such as water that provides an ice bearing including an orifice to allow movement of the length of the filament through the filament closure. Suitable filaments include non-conducting filaments especially optical fibers.
