connecting blocks, by moving the patch cord from one point on the Main Distribution Frame (MDF) to
another.
Optical interconnects consist of Lightguide Interconnect Units (LIUs) without a trough between them.
Figure 301, Typical Optical Interconnect Field,
on page 765 shows a typical Interconnect field. Incoming
and outgoing multi-mode and single-mode cables are connected directly to each other. This arrangement
makes circuit changes more difficult, but reduces optical losses.
