QPM-MTRJ, 100Mb multi-mode FX Quad-Port, MTRJ small-
form-factor

Magnum QPM-MTRJ is a multi-

mode fiber optic quad-port 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 a Quad-Series Fiber Switch, it

supports fiber optic cable distances up the

IEEE-standard 100Mbps distance limits, i.e.,

typically 2km at full-duplex and 412m at half-duplex.

The functionality of this 100BASE-FX multi-mode QPM is essentially the

same as the ST and SC-types. It has the same LEDs per port indicating port activity

(ACT), Link (LK), and FDX or HDX operation. 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.

QPM-MV45, 100Mbps multi-mode FX Quad-Port VF45 small-
form factor

Magnum QPM-MV45 is a quad-port 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 Quad-

Series Fiber Switch, it supports fiber

optic cable distances up the IEEE-

standard 100Mbps distance limits, i.e.,

typically 2km at full-duplex and 412m at

half-duplex.
