Muti Loose Tube Internal/External Cable
36~144 Fibres
|
Description
-
These dielectric Multi-Loose Tube cables are constructed of multiple colour coded loose tubes, each containing 12 colour coded 250µm coated fibres and gel, and the requisite number of filler tubes, stranded around a central strength member. These are bound by water blocking tape and then E-Glass yarn strength members, which also provide rodent resistance. The whole assembly is then enclosed in a black LSZH outer jacket, meeting IEC fire performance requirements.
-
Fibre counts of 36 thru’ 144 are available in all four standard specifications – OM1, OM2, OM3 and OS1 fibres.
