1. The transmission distance is much shorter than the transmission distance of the single -mode light module, and the price is cheaper. In addition, considering the attenuation and dispersing of the light signal during the transmission process, it is recommended that you use the light module with the supported transmission distance slightly greater than the actual requirements. For the short -distance connection between the equipment in the rack, it is recommended that you use a high -speed cable product that is cheaper than the light module.
2. Transmission mode: There are three main data transmission methods: single workers, half -dual -workers, and full dual -work. Single -work transmission only supports data transmission in one direction; semi -dual transmission allows data transmission in two directions. However, only one direction is allowed to transmission in one direction at a certain moment; all -time transmission allows data in two directions to transmit simultaneously. It is better to choose the light module that supports full dual -working transmission.
3. Transmission medium: Copper cables and optical cables are two widely used transmission mediums. Therefore, some optical modules are designed by the power port and some optical modules are designed by optical port. Generally speaking, the optical module is commonly used in 10G and 40G Ethernet transmission applications, while the electric port light module is used in the application of 100M and Gigabit Ethernet, and the transmission distance of the optical module of the optical port is generally compared to the electric port light module Far.
4. heat resistance: The working environment temperature of the light module should not be too high. If the temperature that the light module can withstand, it is likely to have a link failure.
