Next, the HTFuture company will list the differences between some RJ45 modules and SFP optical modules.

1. Different interfaces: The interface of the electrical module is RJ45, while the interface of the optical module is mainly LC, and there are SC, MPO, etc.

2. Different collocations: Electrical port modules are usually used with Category 5, Category 6, Category 6, or Category 7 network cables, while optical modules are generally used in conjunction with optical jumpers.

3. The parameters are different: the electrical module has no wavelength, while the optical module has (such as 850nm1310nm1550nm).

4. Different devices: The devices of the electrical port module and the optical module are different, especially the electrical port module does not have the core device of the optical module - the laser.

5. Different transmission distances: The transmission distance of the electrical port module is short, and the farthest is only 100m. The transmission distance of the optical module can reach 100m to 160km according to the type of optical fiber used.

The above is the difference between the electrical port module and the optical module. In the actual network scenario application, the electrical port module is more widely used in the copper cabling architecture, while the optical module in the optical fiber cabling architecture is more suitable for different scenarios. Transmission needs, we We can also design wavelength division transmission scheme for everyone
