LANmark-OF MBCU Universal B2ca (Up to 36F)

Description and Application
 
This multi micro-bundle construction has an outstanding fire behavior (B2ca S1a a1 d0) and can be installed in tough environment such as railways infrastructure for indoor and outdoor applications.

Design

 This cable structure contains a central strength element surrounded by up to 6 micro-bundles, each containing 6 fibres. A first layer of watertight glass yarns insures the watertighness. An inner LSZH* sheath surrounds this central part. A second layer of watertight glass yarns is covered by a corrugated steel tape armouring providing full rodent protection. The final outersheath is made of LSZH* material.
This cable structure is available with singlemode or multimode fiber The diameter of the fibres is 250 µm. Termination of these fibres can be done with splicing of pigtails.
The cable structure is fully watertight and is provided as a standard, with black colour sheath.

LSZH*: Low Smoke, Zero Halogen material
