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 optical fiber transceivers when deploying a long-distance transmission network.
Optical fiber 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 transceivers can work with single-mode fiber and multi-mode fiber, but multi-mode fiber transceivers cannot work with single-mode fiber.
Single-mode equipment can be used with multi-mode fiber optic transceivers when the optical fiber transmission distance is short. However, technicians still recommend that they be replaced with corresponding fiber optic transceivers as much as possible, so that the equipment can work more stably and reliably without packet loss.
The transmit port (TX) of the transceiver at one end of the dual-fiber device is connected to the receive port (RX) of the transceiver at the other end. Compared with dual-fiber devices, single-fiber devices can avoid the trouble of wrong insertion of the transmitter port (TX) and the receiver port (RX) during use.
Because it is a single-fiber transceiver, only one optical port is TX and RX at the same time, and the optical fiber of the SC interface can be plugged in, 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 when the temperature is too high. Generally, the allowable operating temperature range of optical fiber transceiver equipment is -20℃~+60℃.
The wider operating temperature range can undoubtedly reduce the possibility of unexpected failures for optical fiber transceiver equipment that needs to operate for a long time, and the product reliability is higher.
Most of the front-end cameras of the lightning protection performance monitoring system are installed in the outdoor open-air environment, and the risk of direct lightning damage to the equipment or cables is relatively high.
In addition, optical fiber transceiver equipment is also very sensitive to electromagnetic interference such as lightning overvoltage, power system operating overvoltage, electrostatic discharge, etc., which can easily cause equipment damage, and in severe cases can cause the entire monitoring system to be paralyzed.
Although most optical fiber transceivers on the market are cheap, they do not have lightning protection capabilities.
Some fiber transceiver types on the market such as fiber optic transceiver can only use full-duplex environment and cannot support half-duplex. If it is connected to another brand of switch (SWITCH) or hub (HUB), and it uses half-duplex mode, it will definitely cause serious conflicts and packet loss.
