5.2.1a DFG380XX, 4@10/100Mbps RJ-45 and 2@10Mb multi-mode FX-ST “twist lock” Combo
Module
The DFG380XX is a six port combo module that looks similar to the 100Mb combo module with the
exception of 10Mb speed at the ST fiber module. The ST-connector functions as a fiber optic transceiver to
support 10BASE-FX network segments. When installed in a DFG48000 Managed Switch, the copper port
supports the standard distance 100m on each port and the fiber port supports fiber optic cable distances
up the IEEE-standard 10Mbps distance limits, i.e., typically 2km at full-duplex and 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 FDX/HDX LED to indicate full-duplex mode when lit (or
half-duplex when off). The 10/100 LED indicates the speed, if the LED is ON, 100Mbps if it is OFF, 10Mbps.
5.2.1b DFG380XX, 4@10Mb multi-mode FX-ST “twist lock” Module
The DFG380XX is a 10Mb multi-mode
fiber module with 4 ST-Fiber ports. All four fiber
ports are ST connectors and configured as
10Mb Half-duplex by default. The 10Mb ST-fiber ports
allow the user to connect their legacy 10Mb
network to the DFG48000 switch.
They also provide a convenient way for the half
Duplex hub to connect to the switch
through 10Mb fiber ports. It supports distances
according to the 10Base-FL standard i.e,
2Km distance for multi-mode fiber.
(Single-mode for 10Km distance may be
available as a special order). Each port has
an Activity (ACT) LED indicating packets
being received, a Link (LK) LED indicating
proper connectivity with the remote device
when lit, and FDX/HDX LED indicating
full-duplex mode when lit (or half-duplex if off).
5.2.1c DFG380XX 2@10Mb & 2@100Mb multi-mode FX-ST “twist lock” Module
The DFG380XX is a combo fiber module with two 10Mb + two 100Mb multi-mode fiber module and in
combine 4 ST-Fiber ports. All four fiber ports are ST connectors and configured as 10Mb Half-duplex by
default for10Mb fiber and 100Mb Full duplex for the 100 Mb fibers. The 10Mb ST-fiber ports allow the user
to connect their legacy 10Mb network to the DFG48000 switch. They also provide a convenient way for the
half duplex hub to connect to the switch through 10Mb fiber ports. Whereas the 100Mb ST module allows
to connect the 100Mb demands of Switch devices. It supports distances according to the 10Base-FL
standard i.e, 2Km distance for multi-mode fiber.
