When distances of less than 2 km 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.                                                                 Magnum  RPM-FSC

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.
