MIGE3028-4GF Serial Rack Mounted Industrial Ethernet Switch
The 100M optical interfaces mainly include: SC, ST, and FC, as shown in
Figure 2-2.

Ethernet RJ45 port
Each RJ45 port has an adaptive function that supports automatic
MDI/MDI-X connections. You can connect the switch to a terminal device,
server, hub, or other switch using a straight-through cable/crossover cable.
Each port supports IEEE802.3x auto-sensing, so the most appropriate
transmission mode (half-duplex or full-duplex) and data rate (10Mbps or
100Mbps) can be automatically selected (the connected device must also
support this feature). If the devices connected to these ports do not support
auto-sensing, the port will force itself to work at the same rate as the other
party, avoiding full/half duplex mismatch, the transfer mode will default to
half-duplex, and flow control will be automatically disabled. Gigabit Tx ports
can support up to 1000Mbps.
SFP Gigabit Fx/Tx interface port
This product has four redundant 1000Base-LX full-duplex
single-mode/multi-mode Fx interfaces or 1000Base Tx interface port;
optical/electrical devices use SFP hot-swap devices; fiber interfaces use LC
interfaces, Gigabit Tx port uses the RJ45 interface. The fiber interface needs to
be used in pairs (TX and RX are as a pair).
the TX port is the optical transmitter, and the optical transceiver RX of the
optical interface of another remote switch is connected; the RX port is the
optical transceiver, and the same optical interface is connected to the same
remote switch. The light ends TX.
The SFP device is shown in Figure 2-3.
