Application
The fiber optic (FO) cable is used for transmitting signals with
the help of waves in the optical frequency range. The light beam
is guided by total reflection at the transition from core to cladding
which has a lower refractive index than the core.
The fiber optic cable is provided with a protective coating.
The term “fiber” is often also used for fiber-optic cables (FOC).

Design
Fiber-optic cables with glass fibers , PCF fibers (

ladded
F
iber) and POF fibers (

offered for Industrial Ethernet:
•
Glass fiber-optic cable;
duplex cable for fiber-optic networks indoors and outdoors
•
POF fiber-optic cable;
Duplex cable for POF networks in the indoor area
•
PCF fiber-optic cable;
duplex cable for PCF networks indoors and outdoors
Approvals
UL listing (safety standard) for network cables is especially
necessary for the American and Canadian markets. The require-
ments for the appropriate approvals depend on where the cable
is routed within the building. This applies to all cables which
have to be routed from a machine to a remote control cabinet
and are positioned on cable racks secured in the building.
These cables are identified by the suffix "GP" (general purpose)
in the product name and have the corresponding UL approvals.
