Manufacturer:
Type of cable:
MB
Application:


Use:
For laying inside buildings, in risers, attics, basements and pipelines.

Design: So called «Breakout» cable contains from 4 to 24 single-mode (МВххх-SM) or multi-mode (МВххх-МM) fibers with additional individual protection for each fiber with a layer of kevlar (aramid) threads and protective coating with external diameter 2 mm. Central strength element is made from dielectric material. External coating may be made from both PVC, and not combustion spreading halogen-free low-smoke material– LSZH (Low Smoke Zero Halogen).
