Manufacturer:
Type of cable:
MT
Application:

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

Design:
Cable can contain 4, 8 or 12 single-mode (МTххх-SM) or multi-mode (МTххх-МM) fibers in thick buffer. Space between fibers is filled with high-strength kevlar (aramid) threads. External coating may be made both from PVC plasticate, and not combustion spreading halogen-free low-smoke material– LSZH (Low Smoke Zero Halogen). If there’s a risk of cable damage by rodents, it is recommended to lay the cable in protective plastic tubes
