Abstract
A cable having improved performance during temperature fluctuations includes an outer sheath with a central cavity that does not have a centrally located anchoring member. A plurality of buffer tubes are provided in the central cavity. At least one optical fiber is provided in each of the buffer tubes. The buffer tubes are coupled together to prevent slippage between the buffer tubes, thereby forming a core unit. An adhesive may be provided to couple together the buffer tubes. Alternatively, the buffer tubes may be fused together.
