5.2.3b FPM10-SST, 10Mbps single-mode FL-ST-type, “twist-lock” connector
The Magnum FPM10-SST is a single-mode 10 Mbps fiber optic module equipped with
a dual ST-type connector. To distinguish the single-mode FPM10-SST from the multi-
mode FPM10-MST, the label “Sgl. M.” is at the top of the faceplate of the FPM10-SST.
5.2.4 FPM-MTRJ, 100Mb multi-mode FX, MTRJ small-form-factor
connector
Magnum FPM-MTRJ is a multi-mode fiber optic module equipped with a
small-form-factor MTRJ-type connector. It looks almost like an RJ-45 port, but it is
black in color. The MT-RJ’s small size and
ease of connection make it a good choice for
100Mbps “fiber-to-the-desktop” Ethernet
connectivity. When installed in an 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 functionality of this 100BASE-
FX multi-mode FPM is same as the ST and
SC-types, and it is equipped with the same
ACTIVITY (A) and LINK (L) LEDs to indicate proper connectivity with the remote
device. It has the same “100Mb FX” lettering on the faceplate. Note that the other end
of the fiber cable may have a different connector, not necessarily an MT-RJ type.
5.2.5 FPM-MV45, 100Mbps multi-mode FX, VF-45 small-form-factor
connector
Magnum FPM-MV45 is a multi-mode fiber
FX “small-form-factor” VF-45 connector used primarily
in 100Mbps fiber-to-the-desktop links. Its size is
similar to the MT-RJ port, but the VF-45 shell is
slightly larger. When not in use, its appearance is
distinctive because it has a tiny hinged door over the
port hole to act as a dust cover.
