FiberĆOptic
Cable
The DCSĆNET network requires a 62.5 micron duplex fiberĆoptic
cable. The recommended cable is Belden cable #225362 or
equivalent. This cable has a PVC outer jacket and an internal
Kevlar strength member. This cable is a breakout type of cable
that contains two individuallyĆinsulated, tightlyĆbuffered
fiberĆoptic wires (fibers). This cable may be used in areas where
the ambient temperature will not exceed 80_C (176_F).
Additional cable specifications are provided in Appendix C.
The fiberĆoptic connectors must be STrĆCompatible Multimode
Connectors with ceramic ferrules. Refer to Appendix C for more
information.

Planning for Installation
Use the following procedure to design a fiberĆoptic network that will
achieve maximum signal isolation and cable protection in a specific
environment with minimal fiberĆoptic cable usage.
You will need to select the tools and personnel that are required for
fiberĆoptic cable assembly and installation. Unless you have inĆhouse
expertise with fiberĆoptic cable assemblies and installation, we
recommend that you contact an experienced contractor for making
up and installing fiberĆoptic cables.
Step 1.
Identify the actual location of the AutoMax racks,
StandĆAlone Transceivers, and the Transceiver Rack(s)
using an equipment floor plan.
Step 2.
Identify the tentative fiberĆoptic cable routes. Route the
cables to allow easy access in the future.
Step 3.
Identify the environmental conditions (temperature,
humidity, hazardous chemicals) along the route that may
damage the cable jacket.
Step 4.
Determine how to bypass physical obstructions
(walkways, heat sources, furnaces, caustic chemicals)
along the route that may damage the cable jacket.
Step 5.
Determine the best type of fiberĆoptic cable installation for
each pointĆtoĆpoint link (conduit, raceway, wiring tray).
Step 6.
Calculate the total length of the fiberĆoptic cable for each
link.
Note that the maximum link length is 2000 meters without
splicing.
Step 7.
Document the fiberĆoptic cable system layout. This
document should be maintained for the life of the
installation.
Step 8.
Determine the number of fiberĆoptic cable components
that are needed. Refer to Appendix C for more information
on recommended components.
