RJ45 port supports automatic MDI/MDI-X operation, you can use a
straight line to connect to the PC or server, connect to other switches
or hubs. In the through line (MDI), pins 1, 2, 3, 4, 5, 6, 7, 8 correspond
to the connection; For the MDI-X port of a switch or hub, cross lines
are used: 1-3, 2-6, 3-1, 6-2, 4-7, 5-8, 7-4, 8-5.1000Base-T (X) pins are
defined as follows:
Pin No.

Note: "Tx ±" refers to send data, "Rx ±" refers to received data, and "-"
refers to unused data.
5.2 1000base-FX Ethernet interface
This device provides 1000Base single-mode dual fiber SC module, and
multi-mode like LC, ST as optional.
5.2.1 Patch cord classification
According to the transmission mode of light in the fiber, it can be
divided into multi-mode fiber and single-mode fiber. Multimode fiber
has a thick glass core (50 or 62.5μm), which can transmit light in
various modes. However, the high inter-mode dispersion limits the
frequency at which digital signals can be transmitted, so multimode
fibers can be transmitted over relatively close distances (typically only
a few kilometers).
