Description
OMC’s 1F Toneable Flat Drop cable is a kind of Mini Flat Drop Cable. To construct the cable,A 0.9mm Tight buffer is positioned in middle of the cable,two fiberglass rods are placed diametrically opposite on either side of the fiber core,providing excellent crush resistance and tensile strength during installation and over the lifetime of the cable. A 24 AWG copper wire is aligned along the outside edge of one of the fiberglass rods to provide locatability.The locating wire, strength member rods, and fiber core are then encapsulated in a durable polyethylene (PE) jacket to create a flat cable cross section and lend added protection to the cable core.
This Mini toneable flat drop cable offers a compact, durable, and easy-to-locate optical fiber solution in a readily accessible construction. The fiber optic cable’s webbed design allows the locating wire to be easily separated from the main cable sheath by hand,providing simple, rapid routing and grounding of the locating wire.
Dual Purpose Design:
- The complete cable is used as an outdoor drop
- The inner sub-unit is a stand-alone 900 micron tight buffer fiber
All-Dielectric or Toneable
- All-dielectric version eliminates the need for bonding or grounding
- Optional 24 AWG tone wire is easily separated from the cable
Dry Water-Blocking Technology
- Permits rapid cable preparation and termination
- Water-blocking materials are easily removed
Versatile Design
- Robust outer cable stands up to tough conditions in the outside plant
- Outer cable is easily removed for segments that go indoors
- Simplex sub-unit is compact and UL listed for indoor use, 900-micron tight buffer for easy connection
- Can be used aerially or in duct
Dual Strength Member Design
- Fits into a standard wedge clamp (P-clamp)
- Fully self-supporting
- A great alternative where steel strength members are not permissible
Medium Density Polyethylene Outer jacket
- Low friction installation
- Excellent protection from environmental hazards
Sheath Markings
- Provides positive identification and length verification
- Custom print available
