When fiber cable distances of 2 km or less are needed, the
jumper should be placed across pins 1 and 2.

When fiber cable distances of more than 2 km are
selected, the minimum cable length must also be increased,
as shown in the table above.

RPM-FSC (Fiber SC, Snap-in Connector)
The Magnum RPM-FSC is also a multi-mode fiber optic repeater module, similar to
the RPM-FST. It has the same LEDs indicating port
partitioned (PART), receive activity (RX), and link
operational (LINK). It has the same jumper settings for
extra distance in certain circumstances.
While the functionality of the these two modules
is the same, the RPM-FSC is equipped with an SC-type
"snap-in" connector instead of an ST-type "twist-lock"
connector.

RPM-SMF (Single-mode Fiber)
The Magnum RPM-SMF is a single-mode fiber optic module equipped with a dual ST-
type connector. It functions as a full repeater to support single-mode fiber networks. The RPM-
SMF supports fiber optic transmission
distances of up to 10 Km. The RPM-SMF
includes full transceiver functionality and
does not require an external transceiver
device.
This module is equipped with
PART, RX, and LINK LEDs identical to
those of the RPM-FST.
