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.
When installed in a Magnum 4K8 Full-duplex Switch, it supports fiber optic
cable distances up to the 100Mbps Full-duplex non-collision-domain distance limits, i.e.,
typically 2000 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.
5.2.6 FPM-Blank
The FPM-Blank is a blank face
plate that must be installed in any empty
FPM slot. When the Magnum 4K8
chassis contains less than twelve front-
mounted FPMs, the empty front slots
must be covered with the
FPM-Blank
FPM-Blank face plate in order to maintain proper cooling air flow, and for safety, etc.
