This tight buffer cable is designed for indoor/outdoor installation.
This cable has an outstanding fire behaviour.
Direct connectorization is made easy with 900µm buffered structure.
This cable can be operated under a large temperature range.
Design
The TBU LSZH* SP1724 cable has a central strength member (FRP: Fibre Reinforced Plastic), with 900µm buffered structure around. The design is reinforced by a layer of glass yarns and a LSZH* sheath.
Fibre type
The TBU LSZH* SP1724 cable is available with singlemode and multimode fibres.
Technical performances
The tight buffer cable performances are specified in the following tables.
Additional details
This cable is provided as a standard with a black sheath, other sheath colours are also available. Long exposure to UV with these other colours could generate colour fading.
Euroclass
