RPM-FST (Fiber ST, Twist-lock Connector)

The Magnum RPM-FST is a multi-mode fiber optic module equipped with a dual ST-type connector. It functions as an IEEE 802.3 full repeater to support 10BASE- FL and FOIRL network segments. When used for 10BASE-FL segments, this module supports fiber optic transmission

distances up to 2000m. For FOIRL

10BASE-FL, FOIRL

ST Connectors

applications, it supports fiber segments

 

of up to 1000m in length. The RPM-

 

FST includes full transceiver

1

functionality and does not require an

2

external transceiver device. In

3

 

addition to Partition (which is

1 LINK 2 Partition 3 Receive

inoperative on Model 1000 Hubs) and

 

Receive (RX) LEDs, a LINK LED indicates proper

Magnum RPM-FSTconnectivity with the remote device.

NOTE: The RPM-FST circuit board contains a six pin jumper which controls the intensity of the transmitted signal. By default, the jumper is placed across pins 1 and 2. The jumper may be set as follows to

accommodate distances of up to 4 km:

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.
