Use of Multi Fibers

The EMS provides the ability to install “multi fibers” between a Host and Remote.

This means that, in addition to the minimum single fiber pair (RX and TX) in the

Host to Remote connection, one or more additional fiber pairs are installed. This

is done to increase the bandwidth or number of timeslots between the Host and

Remote.

Each fiber pair can handle approximately 75 MHz of RF bandwidth and each fiber

is capable of supporting 12 timeslots, as described in

“DART Modules” on page 24.

When a Host DART is linked to a Remote DART in a multi-fibers configuration, the

EMS uses the first fiber (in numerical order) on which the required number of

timeslots is available for the passband being linked. The EMS will not divide up the

timeslots between two fibers. So, for example, if the passband requires eight

timeslots, and only six timeslots are available on the first fiber, the EMS will bypass

the first fiber and assign all eight timeslots to the second fiber, leaving four

timeslots unused on the second fiber.
