Fiber Optic Cables
The 1756-M03SE, 1756-M08SE, and the 1756-M16SE modules are
connected to the drive(s) via a fiber optic cable. These cables can be made of
either plastic or glass. For more information about the care, handling, and
installation of fiber optic cables see the
Fiber Optic Cable Installation and
Handling Instructions
, publication number 2090-IN010x-EN-P.
Plastic Fiber Optic Cables
The modules are connected to the drive(s) via a 1000
µ
m plastic simplex fiber
optical cable. Plastic fiber optic cables have a transmission range of 1 meter to
32 meters. Both the transmitter and receiver connections are made using a
F-SMA standard plug that conforms to the F-SMA screw type connector.
Premade plastic fiber optic cable assemblies are available from Rockwell
Automation. Plastic fiber optic cables come in a variety of jackets depending
on application environments. The cable is available without a jacket
(Chlorinated Polyethylene) for use inside an electrical cabinet, a standard
jacket (Polyvinyl Chloride) for use outside of electrical cabinets, and a nylon
jacket for use in harsh environments.
The following table shows the catalog numbers and available lengths for
plastic fiber optic cables that are not jacketed (Chlorinated Polyethylene) and
should be used only within an electrical cabinet.
