QPM-MSC 100Mbps multi-mode FX-SC Quad-port, “snap-in”
connector
The Magnum QPM-MSC is a multi-
mode 100Mbps fiber optic transceiver module,
similar to the QPM-MST. It has the same LEDs
indicating port activity (ACT), Link (LK), and
FDX or HDX operation, and the same face-plate
lettering.
While the functionality of these two
modules is essentially the same, the QPM-MSC is equipped with an SC-type "snap-in"
connector instead of an ST-type.
5.2.3
QPM-SSC 100Mbps single-mode FX-SC-type, “snap-in” connector
The Magnum QPM-SSC is a
single-mode 100Mbps fiber optic
module equipped with a dual SC-type
connector. It functions as a fiber optic
transceiver to the Quad-Switches,
supporting four single-mode fiber
network segments.
The QPM-SSC, when installed
in a Magnum Quad-Series Fiber Switch
operating at 100Mbps full-duplex,
supports single-mode fiber cable lengths of as much as 25+ Km (see Power Budget,
Section 4.5)
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). To
distinguish the single-mode QPM-SSC from the multi-mode QPM-MSC, the label “Sgl.
M.” is at the top of the faceplate of the QPM-SSC.
