When installed in a Magnum 8000X half-duplex hub, it supports fiber optic
cable distances only up the 100Mbps shared-collision-domain distance limits, i.e.,
typically 200 meters.
The small size, about the same as an RJ-45, reduces the size of wiring panels
in wiring closets while providing the advantage of “future-proof” fiber optic
technology.
The cable port is a “plug-in” connector, with both fiber strands terminated in
one housing that cannot be improperly inserted. The module is equipped with a LINK
(L) LED to indicate proper connectivity with the remote device, and an ACTIVITY (A)
LED that flashes to show when Fast Ethernet packets are being received.

FPM-SXMST and SXMSC (100BASE-SX) when available !!
The FPM-SXMST port module,
better known as “short wavelength Fast
Ethernet,” looks essentially identical to other
ST and SC connectors. The FPM-SXMST
based on 870 nm wavelength comes in multi-
mode only, and may eventually become a
cheaper solution for Fast Ethernet fiber-to-
the-desktop segments.
FPM-SXMST supports fiber
transmission connectivity up to 300m distance is suitable for the users requiring higher
bandwidth in their LANs.
However, the connection of fiber
cable to the FPM-SXMST is the same as other
ST-type “Twist-lock” connectors. The module
is equipped with Activity(A) and Link(L)
LEDs to indicate proper connectivity with the
remote device.
As an additional indicator, a multi-
mode SX 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
