2.2.2 Quad-port modules, 100Mb fiber
Fig.2.2.2 Fiber Quad-Port Modules, QPM ST, QPM-SC, QPM-MTRJ, QPM-MV45
In a fiber quad-port module, all of the fiber ports are of the same speed, the
same multi- or single-mode, and the same connector type. Multi-mode 100Mbps models
are available with ST, SC, MTRJ, and VF-45 connectors. Single-mode 100Mbps models
are available with SC connectors.
The 100Mb fiber quad-port modules on the Magnum Q-Series normally are set
(factory default) to operate in full-duplex mode for best fiber distance and performance.
On the Magnum Q-Series, the user may select full- or half-duplex mode per-port with an
internal jumper setting (See Section 3.4) for the flexibility to adapt to any type of Fast
Ethernet devices.
On Magnum fiber QPMs, there are three LED’s per fiber port. The Link (LK)
LED indicates “ready for operation” when lit, another LED indicates operation in full-
duplex mode when ON (when it is OFF, operation is half-duplex), and an LED indicates
Receiving Activity (ACT) on the port. A fiber cable must be connected to each 100Mb
port and a proper link (LK lit) must be made with the device at the other end of the cable
in order for the LK LEDs to provide valid indications of operating conditions.
