Abstract
Embodiments of the present disclosure provide an apparatus and method for manufacturing of optical cable buffer tubes using an emulsion lubricant. In an embodiment, an optical cable includes a plurality of buffer tubes. Each buffer tube includes a bundle of optical fibers comprising an outer surface area, a swellable-thread comprising a hydrophilic base material comprising water, and a layer of silicone contacting at least a part of the outer surface area.

A buffer tube comprising:
- a bundle of optical fibers comprising an outer surface area,
- a swellable-thread comprising a hydrophilic base material comprising water, and
- a layer of silicone applied as an emulsion lubricant to the bundle of optical fibers, the layer of silicone contacting at least a part of the outer surface area, the emulsion lubricant comprising silicone, the water, and an emulsifying agent.
An optical cable comprising:
- a central strength member disposed in a central region of the optical cable;
- and
- a buffer tube disposed in a peripheral region of the optical cable, the buffer tube comprising
- a swellable-thread comprising a hydrophilic base material comprising water,
- a bundle of optical fibers disposed around the swellable-thread, the bundle of optical fibers comprising an outer surface area, and
- a layer of silicone applied as an emulsion lubricant to the bundle of optical fibers, the layer of silicone disposed at an inner surface contacting at least a part of the outer surface area of the bundle of optical fibers, the emulsion lubricant comprising silicone, the water, and an emulsifying agent.
