The Loose Tube Cable with Turning Points (LTC TP) is a metallic, longitudinally water-protected, stranded loose tube outdoor duct cable. Due to detectable turning points (TP), this cable is particularly suitable for the flexible use of branch-off closures in FTTX networks. For splicing, extra cable overlength is not necessary. Installation: by blowing or pulling, into conduits or on cable trays.
