TBU LSZH 24x50/125 OM4 SP1724 BK
Country ref. 1084274
StandardsInternational : EN 50399 D; IEC 60332-1; IEC 60332-3; IEC 60754-1; IEC 60794; IEC 61034
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 24 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.
Black or colored stripes are used for the fibre identification from position 13 to 24.
