What is the difference between indoor and outside cables

The difference between indoor cables and outside cables. Generally, outside cables are designed to resist water penetration by using a gell fill or dry water-blocking compounds and a polyethylene jacket.


The new dry cables are getting very popular, since they can be made as distribution types which are easier to terminate.


Many also have a PE jacket over a UL-rated PVC jacket so you can bring the cable into the building, strip off the outside jacket and run it anywhere in the building (not the 50 feet limit of PE.)


Indoor or premises cable must be rated for flame retardance for safety and to meet code.

Tight Buffered Fibre

Tight buffered fibre is manufactured by extruding a layer of buffer material (PVC, LSZH, ETFE, etc) on the  sruface of the fiber. Through the selection of high-quality material, dedicated equipments and precision moulds for production, the tight buffered fibre delivers excellent performance.

Simplex Cable(GJFJV)
The Simplex cable uses single 900μm or 600μm tight buffered fibre as optical transmission medium, covered with aramid yarn as Strength member, then extruded with a PVC sheath. Other sheath materials, like LSZH and TPU, are available on request.
