Tight Buffered Cable Applications

• Indoor / Outdoor Applications Where Gel-Filled Cables are not Suitable
• Robust Cables for Indoor Applications where the Cable may be Subject to a Damp / Moist Environment
• Indoor / Outdoor Applications where Termination is Directly onto Conventional Connectors (w/o Pigtail Splicing)
• Suitable for Lashed Aerial, Duct, Underground Conduit and Indoor Riser Applications
