4.2.5 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. Please
refer to Section 3.2.4. for details.

4.2.6 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. To distinguish
the single-mode RPM-SMF from the multi-mode Magnum RPM-SMF
RPM-FST, the label “Sgl. M.” is at the top of the faceplate of the RPM-SMF. As an
additional indicator, a multi-mode TX port emits light (red in color) that is in the visible
spectrum and which can be seen by looking into the port with the power on and with no
cable connected. The single-mode TX port emits light outside of the visible spectrum
and will always look dark to the human eye.
Note: Be sure to use single-mode fiber optic cable with this module. Single-mode fiber
cable has a smaller diameter than multi-mode fiber cable (2/15 - 8/60 microns for single-
mode, 50/125 or 62.5/125 microns for multi-mode, where xx/xx are the diameters of the
core and the core plus the cladding respectively).
