Description
This multi micro-bundles cable is designed for indoor/outdoor installation in railways infrastructure.
The corrugated steel armour provides a high rodent protection. This cable has an outstanding fire behaviour.
Access to µbundles is made easy with the internal ripcord.
This cable can be operated under a large temperature range.
Design
This MBC LSZH* cable has a central strength member (FRP : Fibre Reinforced Plastic), with 1 single bundle containing 6 fibres around. The design is reinforced by a first layer of watertight glass, a LSZH* inner sheath, a second layer of watertight glass yarns, a corrugated steel armour and a LSZH* outer steath.
Fibre type
The MBC LSZH* cable is available with singlemode and multimode fibres.
Technical performances
The multibundle 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.
The sheathing material is compliant with ISO 4892-2 regarding the UV exposure.
The cable is compliant with the standard NFPA - IEEE1202&UL1685.
