TBU LSZH 6xSM G652D SP1724 BK
StandardsInternational : EN 50399 D; IEC 60332-1; IEC 60332-3; IEC 60754-1; IEC 60794; IEC 61034
National : NF C 32-070/C1
Declaration of Performance : Reaction to fire: Dca-s1,d0,a1
according to EN50575:2014+A1:2016
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.
The TBU LSZH* SP1724 cable has a central strength member (FRP: Fibre Reinforced Plastic), with 6 900µm buffered structure around. The design is reinforced by a layer of glass yarns and a LSZH* sheath.
The TBU LSZH* SP1724 cable is available with multimode and singlemode fibres.
The tight buffer cable performances are specified in the following tables.
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.
