5.2.1
QPM-MST, 100Mb multi-mode FX-ST Quad-port Module, “twist
lock”
The Magnum QPM-MST is a multi-mode 100Mbps fiber optic quad-port
module equipped with dual ST-type
connectors. It functions as a fiber optic
transceiver to support 100BASE-FX
network segments. 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.
Each port has an Activity (ACT) LED indicating packets being received, a
Link (LK) LED that indicates proper connectivity with the remote device when lit, and a
FDX/HDX LED to indicate full-duplex mode when lit (or half-duplex when off).
Lettering on the front of the module identifies it as “100 FX” to avoid confusion with
other similar-looking 10 Mb fiber QPMs.
5.2.1a
QPM10-MST, 10 Mbps multi-mode FL-ST-Quad-port type, “twist-lock”
The Magnum QPM10-MST is a multi-mode 10 Mbps fiber optic module equipped with
dual ST-type connectors. It looks similar to the 100Mb QPM-MST, but has the lettering
“10 Mb” on the front to distinguish it. It supports fiber optic cable distances up the
IEEE-standard 10 Mbps distance limits, i.e., typically 2km at full-duplex and at half-
duplex.
Each port has an Activity (ACT) LED indicating packets being received, a
Link (LK) LED that indicates proper connectivity with the remote device when lit, and a
FDX/HDX LED to indicate full-duplex mode when lit (or half-duplex when off).
Lettering on the front of the module identifies it as “10 FL” to avoid confusion with other
similar-looking 100Mb fiber QPMs.
