Simplex/duplex cable I-V(ZN)H

Indoor cables for producing assembled connection cables for any network topology.

Depending on the transmission rate required and the distance to be covered, either multimode fibers with various specifications or singlemode fibers are used for these cables.

To comply with the strict fire safety requirements for indoor applications, cables with halogen-free and flame-retardant cladding are required, since these ensure that a fire is not propagated further along cables, and that cables do not produce corrosive or toxic gases.
