A concentric insulation sleeve is disclosed having multi-layered structure. The outer layer exhibits low smoke and fume and non-halogen properties important for use of fiber optic cable assemblies in confined space susceptible to combustion conditions. The inner layer exhibits anti-static properties, and optionally slippery properties, to make the assembly of fiber strands in the insulation less charged with static electricity. The cable can become associated with other cables and serve as mini-ducts and then be surrounded by another insulation sleeve of the same construction to form a cable duct.
