5.2.1 FPM-MST, 100Mbps multi-mode FX-ST-type, “twist-lock”
connector
The Magnum FPM-MST is a
multi-mode 100Mbps fiber optic
module equipped with a dual ST-type
connector. It functions as a fiber optics
transceiver to support 100BASE-FX
network segments. When installed in a
Magnum 4K8 Full-duplex Switch, it
supports fiber optic cable distances up
to the IEEE-specified 100Mbps at full-
duplex non-collision-domain distance limits, i.e., typically 2000 meters.
The module is equipped with an Activity (A), and a Link (L) LED which indicates
proper connectivity with the remote device when lit. Lettering on the front of the module
identifies it as “100 FX” to avoid confusion with other similar-looking FPMs.
5.2.1a FPM10-MST, 10 Mbps multi-mode FL-ST-type, “twist-lock”
connector
The Magnum FPM10-MST is a multi-mode 10 Mbps fiber optic module
equipped with a dual ST-type connector. It looks similar to the 100Mb FPM-MST, but
has the lettering “10 Mb” on the front to distinguish it.
5.2.2 FPM-MSC 100Mbps multi-mode FX-SC-type, “snap-in”
connector
The Magnum FPM-MSC is also a
multi-mode 100Mbps fiber optic transceiver
module, similar to the FPM-MST. It has the
same LEDs indicating port activity (A), and
Link (L) operational, and the same face-plate
lettering.
While the functionality of the these
two modules is the same, the FPM-MSC is
equipped with an SC-type "snap-in"
connector instead of an ST-type.
