Many people are not very clear about electrical port modules, or they are often confused with optical modules, and cannot choose electrical port modules correctly to meet the mutual benefit of transmission distance requirements and cost optimization. This article will introduce you to the comparison of the electrical port module, so that you can understand the electrical port module more thoroughly.
Both electrical port modules and optical modules can be applied to switches and other equipment to realize photoelectric conversion. Before talking about the difference between electrical port modules and optical modules, let's take a look at electrical ports and optical ports. The electrical port is what we often call the network port (RJ45), which is used to connect the network cable and the coaxial transmission cable to transmit electrical signals; the optical port is the optical fiber socket, which is used to connect the optical cable. The optical port on the switch generally uses an optical module to transmit light. Signal.
The difference between the electrical module and the optical module is mainly in the interface, collocation, parameters, components and transmission distance.
The interface is different: the interface of the electrical module is RJ45, and the interface of the optical module is LC, SC, MTP/MPO, etc.
The matching is different: the electrical module is used with the network cable, and the optical module is connected with the optical fiber jumper.
The parameters are different: the parameters of the electrical module have no wavelength, while the wavelengths of the optical module are 850nm, 1310nm and 1550nm.
Different components: The electrical module does not have the core component of the optical module - the laser.
The transmission distance is different: the maximum distance of the electrical module is 100 meters, and the maximum transmission distance of the optical module is 160 kilometers.
Compared with traditional optical modules, DACs and AOC interconnects, what are the advantages and disadvantages of electrical modules? Take 10G Ethernet interconnection as an example: electrical port module VS high-speed cable VS optical module VS active optical cable
