Tekniksat as an option also
offers a dedicated rack for it.
To complete the system,
we needed a device located
at the other end of the op-

from light to RF electric
current. We used another
Tekniksat product: the TFM
41/10 C Optical Multiswitch.
Conversely to the optical
transmitter, it has only one
input but many outputs. Of
course, the input is an opti-
cal port and the output are

coax cables are hooked up.
There are no less than 10
subscriber outputs to which
you can directly connect
satellite/terrestrial receiv-
ers. Additionally, there are
16 trunk outputs that regen-
erate the signals from the
four LNBs connected at the
other end of the system. You
can connect classical (coax)
multiswitches to these trunk
output and increase the
number of subscriber out-
puts if needed. There is one
additional input for a ter-
restrial signal that may be
used if this kind of signal is
not originally inserted at the
