Specifications
At each end of a fiber optic cable is a Fiber Interface
Module (FIM). At the transmitting end, the FIM converts
electrical signals into pulses of light to be transmitted
over the cable. At the receiving end, the FIM converts the
pulses of light back into electrical signals usable by the
node.
The FIM connects the 3300 Controller to a peripheral
unit, NSU or DSU. These FIMs cannot be installed in the
Applications Gateway. Each FIM variant may be
identified by its optical wavelength and fiber type
(indicated on the FIM faceplate). The same FIM variant
must be used at each end of a fiber optic cable. However,
a node may be equipped with different FIM variants to
suit the length of each cable run.
