Precautions for new users to use Fiber Optic Transceiver

Optical fiber transceiver has a variety of different types, but in actual use, most of the attention is divided by the optical fiber connector different categories: SC connector Optical Fiber transceiver and FC/ST connector Optical Fiber transceiver.
When connecting to different devices using optical fiber transceiver, you must note that the ports used are different.
1. optical transceiver to 100BASE-TX device switch, Hub) connection:
It is confirmed that the length of the twisted pair cannot exceed 100;
Connecting one end of the twisted pair to the RJ-45 port Uplink port of the optical fiber transceiver), the other end to 100BASE-TX with a switch, Hub) RJ-45 port common port ).
2. optical transceiver to 100BASE-TX device Nic) connection:
It is confirmed that the length of the twisted pair cannot exceed 100;
Connect one end of the twisted pair to the RJ-45 port 100BASE-TX port of the optical transceiver, and the other end to the RJ-45 port of the NIC.
3. optical transceiver to 100BASE-FX connection:
Confirm that the optical fiber length does not exceed the distance range provided by the device;
One end of the optical fiber is connected to the SC/FC/ST connector of the optical fiber transceiver, and the other end is connected to the SC/ST connector of the 100BASE-FX device.
In addition, many users consider that the fiber optic transceiver can be used normally as long as the length of the fiber is within the maximum distance supported by the single-mode fiber or multi-mode fiber. In fact, this is a wrong understanding. This recognition is correct only when the connected devices are full-duplex devices. When there is a half-duplex device, the optical fiber transmission distance is limited.
