Chapter 3 Installing Supervisor Engines Attaching the Network Interface Cables A mode-conditioning patch cord is an optical fiber cable assembly that consists of a pair of optical fibers terminated with connector hardware. Specifically, the mode-conditioning patch cord is composed of a single-mode optical fiber permanently coupled off-center (see Offset in Figure 3-7 and Figure 3-8) to a graded-index multimode optical fiber. Figure 3-7 and Figure 3-8 show a diagram of the mode-conditioning patch cord assembly.

Attaching the Network Interface Cables
A mode-conditioning patch cord is an optical fiber cable assembly that consists of a pair of optical fibers
terminated with connector hardware. Specifically, the mode-conditioning patch cord is composed of a
single-mode optical fiber permanently coupled off-center (see Offset in
Figure 3-7
and
Figure 3-8
) to a
graded-index multimode optical fiber.
Figure 3-7
and
Figure 3-8
show a diagram of the
mode-conditioning patch cord assembly.
