Description
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 24 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 multimode and singlemode 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.
Black or colored stripes are used for the fibre identification from position 13 to 24.
