In network construction and application, since the longest transmission distance of the network cable is generally 100 meters, it is necessary to use relay equipment such as fiber optic transceivers when deploying a long-distance transmission network.
Fiber optic transceivers are generally used in practical network environments where Ethernet cables cannot cover and optical fibers must be used to extend the transmission distance. So, what problems should be paid attention to when using fiber optic transceivers?
Single-mode fiber optic transceivers can work with single-mode fiber and multi-mode fiber, but multimode fiber transceivers cannot work with single-mode fiber.
Single-mode equipment can be used with multimode fiber transceivers when the optical fiber transmission distance is short. However, the technical personnel still suggest that the corresponding fiber optic transceiver should be replaced as far as possible to match the use, so that the equipment can work more stable and reliable, and there will be no packet loss.
The transmit port (TX) of the transceiver at one end of the dual-fiber device is connected to the receive port (RX) at the other end of the transceiver. Compared with dual-fiber equipment, single-fiber equipment can avoid the trouble of wrong insertion of the transmitter port (TX) and the receiver port (RX) during the use.
Because it is a single-fiber transceiver, only one optical port is TX and RX at the same time, so just plug in the optical fiber of the SC interface, which is easier to use. In addition, single-fiber equipment can save fiber usage and effectively reduce the overall cost of the monitoring solution.
The fiber optic transceiver itself will generate high heat when used, and the fiber optic transceiver will not work properly if the temperature is too high. Generally, the allowable operating temperature range of fiber optic transceiver equipment is -20℃~+60℃.
The wider operating temperature range can undoubtedly reduce the possibility of unexpected failures for fiber optic transceiver equipment that needs to operate for a long time, and the product reliability will be higher.
Most of the front-end cameras of monitoring system for the lightning protection are installed in the outdoor open-air environment, so the risk of direct lightning damage to the equipment or cables is relatively high.
In addition, fiber optic transceiver equipment is also very sensitive to electromagnetic interference such as lightning overvoltage, operating overvoltage of the power system, electrostatic discharge, etc., which can easily cause equipment damage, and in severe cases can cause the entire monitoring system to be paralyzed.
Although most fiber optic transceivers on the market are cheap, they do not have lightning protection capabilities.
Some fiber optic transceivers on the market can only use full-duplex environment and cannot support half-duplex. If it is connected to another brand's switch (SWITCH) or hub (HUB), and it uses half-duplex mode, it will definitely cause serious conflicts and packet loss.
