Fiber-Optic Cable Assembly
Components
Fiber-optic cable assemblies are composed of two main components: the connectors
and the cable itself.
2.1 Cable
The UDC module and the PMI require a 62.5 micron duplex fiber-optic cable.
The recommended 62.5 micron fiber-optic cable is Belden cable #225362, Mohawk
cable #M92021, or equivalent. This cable has a PVC outer jacket and an internal
Kevlar strength member. This cable is a breakout type of cable which contains two
individually insulated fiber-optic wires (fibers). This cable may be used in areas where
the ambient temperature will not exceed 80×C (176×F).
Note that 50 micron fiber-optic cable is an acceptable substitute for 62.5 micron cable.
Refer to Appendices A, B, and C for more information.
2.2 Connectors
The fiber-optic connectors must be ST ® -Compatible Multimode Connectors with
ceramic ferrules. Refer to Appendix D for more information.
A coupler is required when connecting two fiber-optic cables together. An
ST-Compatible Multimode Coupler or equivalent is recommended. Refer to
Appendix D for more information.

ATTENTION: Turn off, lock out, and tag the power to both the rack
containing the UDC module and to its corresponding PMI hardware
before viewing the fiber-optic cable or transmitter under magnification.
Viewing a powered fiber-optic transmitter or connected cable under
magnification may result in damage to the eye. For additional information
refer to ANSI publication Z136.1-1981. Failure to observe this precaution
could result in bodily injury.
