User Guide

Connect the Two-Channel Two-Wire Intercom System (1) and CommLink TR6442i Fiber
Optic Intercom Link Unit "A" (2). In this example it is assumed that the CommLink TR6442i
Fiber Optic Intercom Link is powered from the intercom. Run a Single Strand Fiber Cable
(3) between CommLink TR6442i Fiber Optic Intercom Link Unit "B" (4) and power the
CommLink TR6442i Fiber Optic Intercom Link using the appropriate power supply (5).

Connect your intercom Belt Packs in normal daisy chain fashion to the CommLink TR6442i
Fiber Optic Intercom Link. The number of Belt Packs will depend on whether they are self-
powered or are powered by the CommLink TR6442i Fiber Optic Intercom Link. When
powered by the CommLink TR6442i Fiber Optic Intercom Link you can expect 5 units to
work per channel.

Remember that CommLink TR6442i Fiber Optic Intercom Link "A" must have a WDM factor
different from CommLink TR6442i Fiber Optic Intercom Link "B." You must use a WDM
@1550nm unit at one end of the fiber cable and a WDM@1310 at the other end of the fiber
cable.

In this example two Mussel Shell versions of the CommLink TR6442i Fiber Optic Intercom
Link are used. It makes no difference which of the three physical versions is used so long as
the WDM factors are different as described above.
