Summary of knowledge of SFP electric port light module

First of all, let's briefly understand what the power port module is.

The electric port module is also known as the optical port to power port module and the optoelectronic conversion optical module. It is a kind of supporting hot plug -in module, the format form is SFP, and the connector type is RJ45. Based on the different rates, it can be divided into 1000m, 10/100/1000m, 10/100m, and 10G SFP+power port modules.

The electric port module complies with the SFP MSA and IEEE STD 802.3-2002 standards, and has the characteristics of low power consumption, high performance, and compact design. Mainly used in short -range data transmission.

Both the power port module and the optical module can be applied to the switch. The function is to achieve photoelectric conversion. So what is the difference between the power port module and the optical module? Let's learn together!

Different interfaces: The interface of the power port module is RJ45, and the interface of the light module is mainly LC, as well as the SC and MTP/MPO interface.

Different matching: The electric port module is usually used with the five, six, super six or seven types of network cables, and the light module is generally connected to the light jumper.

Different parameters: The parameters of the power port module do not have wavelengths, but the light module is available. The commonly used is 850nm, 1310nm, and 1550nm.

Different components: The electric port module does not have the core component of the light module -laser.
