Fiber Optic Pressure

Fiber optic communication cable connections

When the Fiber Optic Pressure Module is the only optional module, it connects to the
ERT Control/Gating Module using a duplex fiber optic cable. The cable should be
connected to the fiber optic ports labeled "option in" and "option out" and the options I/O
switch should be set to "options in use". When other optional modules are also present,
the modules connect to form a data loop with one of the duplex fibers connecting to the
st
1 optional module and the other of the duplex fibers connecting to the last optional
module. The modules are then connected to each other using short simplex fiber optic
cables.
The fiber optic cables have blue and grey connectors. The driver and receiver ports are
also blue and gray. The order of the modules in the data loop is not important. But, in
all cases the color of the connector must match the color of the port
.
Handling and cleaning fiber optic pressure sensors
The sensors have a SC male connector on one end and a small
pressure transducer on the other end. A white silicone jacket covers
the fiber optic cable except for the last few inches near the
transducer. For the larger sensor (FOP-5-4) the diameter of the
transducer is 0.4 mm and the diameter of the fiber optic cable
without the jacket is 0.2 mm, so the transducer diameter is
considerably larger than the fiber diameter as shown in the
photograph.
